For example, a washing machine is controlled by a microcontroller; most likely our watch is too; there is also one in a microwave. Of course, all these microcontrollers already have their application programs. This Raspberry Pi Pico 2W is a microcontroller board that can perform physical computing and can be easily reprogrammed over a USB connection. Gary from the Gary Explains channel helps to highlight the boost of Pico 2 or RP2350:  Pin-to-Pin Compatible with 1st Generation of Pico WThe Raspberry Pi Pico 2W maintains complete pin-to-pin compatibility with its predecessor, the Raspberry Pi Pico W. This ensures a seamless transition for existing projects and carrier boards, allowing users to leverage their existing investments and expertise. Developers can effortlessly migrate their code and hardware designs to the new Pico 2W, benefiting from enhanced performance and expanded capabilities without the need for extensive modifications. We have tested the Raspberry Pi Pico 2W on the following boards and it works effortlessly:Maker Pi Pico BaseRobo PicoMaker Pi Pico Mini Base  Work Seamlessly with Raspberry Pi Computer You can always connect the Raspberry Pi Pico 2W to any preferred computer with Windows, macOS, and Linux that supports Python 3.0, yet connecting it with the Raspberry Pi Single Board Computer will be perfect as the same team designs it. The official Operating System, Raspberry Pi OS comes pre-installed with Thonny Python IDE which is ready for you to get started writing MicroPython code for Pico. If you are using another OS (Windows, macOS, or other Linux distribution), please visit https://thonny.org/ to download the IDE and install it. A More Powerful MCU Dev Board (Dual-Core ARM Cortex-M33)Raspberry Pi Pico W comes with dual ARM Cortex-M0+, while the new Pico 2W comes with a Dual-Core ARM Cortex-M33 and a Dual-Core RISC-V Hazard3. Flexible clocking system, with configurable up to a maximum speed of 150MHz! This tiny MCU comes with a whopping 520 Kbyte of SRAM, an external QSPI Flash with a capacity of 4 MByte, and enhanced eXecute In Place (XIP v2). Larger RAM and Flash size enable you to write high-level programming languages like MicroPython and CircuitPython for Raspberry Pi Pico 2W.  New Pico 2 Series with Wireless by Raspberry Pi  Compact and Ready to be Mounted into the Product Raspberry Pi Pico 2W preserves the good of its presuccesor, it is ready to be embedded in any product out of the box. If you choose the version without pre-soldered headers, it is ready for SMT (Surface Mount Technology). Raspberry Pi Pico 2W is extended out to a 40-pin 21x51 DIP (Dual Inline Package) style, 1mm thick PCB with 0.1" (100mil) through-hole pins. The pins are further extended to the PCB edge with a castellated circuit board. This enables it to be soldered to another PCB board without the need for extra header pins, making it a smaller and more compact finished product. Awesome! A good example is Cytron’s Maker Pi Pico (1st generation of Pico): Meanwhile, the version with pre-soldered headers is breadboard-friendly, so students, makers, and engineers can use the Raspberry Pi Pico 2W on a breadboard or any standard PCB board for development or prototyping. If the Raspberry Pi Pico 2W is inserted onto a breadboard, there are two rows of jumper holes on both sides of the PCB for prototyping. Note:  The Raspberry Pi Pico 2W GPIO runs at 3.3VDC. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.Enhanced version of Raspberry Pi Pico W, officially from Raspberry PiRP2350A MCU designed from the ground up by engineers of the Raspberry Pi TeamCPU: (either)Dual ARM Cortex-M33 Cores Dual RISC-V Hazard3 CoresWireless Capability, CYW43439:2.4GHz 802.11n WiFiBluetooth 5.2PCB AntennaSystem clock up to 150MHzSRAM: 520KByte4MByte QSPI Flash MemoryComprehensive Security:ARM TrustZoneOptional boot signing, enforced by on-chip mask ROM, with key fingerprint in OTPProtected OTP storage for optional boot decryption keyGlobal bus filtering based on ARM or RISC-V security/privilege levelsPeripherals, GPIOs, and DMA channels individually assignable to security domainsHardware mitigations for fault injection attacksHardware SHA-256 acceleratorXIP v2 for better flash memory interfaceReady with USB Micro B receptor for Power and DataSupport USB 1.1 Host and DeviceConnected to the USB port and it will appear as USB Mass Storage by default, no driver is neededSupports CircuitPython, MicroPython, C and C++, Arduino IDE Programming LanguageDrag and Drop Program loading method, just like moving files in Windows ExplorerComes in 40-pin 21x51 'DIP' style 1mm thick PCB with 0.1" through-hole pins, breadboard-friendlyWith the edge castellations PCB, it is ready to be mounted on another PCB without an additional header pin, SMD-friendlyTwo options:Comes with PRE-SOLDERED header pins (by Cytron Technologies), breadboard-friendlyComes without header, SMD-friendlyPeripheral rich:Extended out 26 multifunction 3.3V General Purpose I/O (GPIO)23 GPIO are digital-only3 x 12-bit ADC capable of 500Ksps, Analog to Digital Converter2 x UART (Universal Asynchronous Receiver/Transmitter)2 x SPI (Serial Peripheral Interface)2 x I2C (Inter IC)16 x PWM (Pulse Width Modulation)3 x Programmable IO (PIO) blocks, 12 PIO pins that can emulate high-speed interfaces such as SD card or VGABuilt-in 12-bit ADC temperature sensor3-pin ARM Serial Wire Debug (SWD) portOnboard Programmable LED, GP25Simple yet highly flexible power supply architectureSupport USB power, external supply (2 - 5VDC), or battery power.Comprehensive SDK, software examples, and documentationOfficially from Raspberry PiOperating Temperature:  -20ºC to +85ºCCompatible with any computer with a USB port, Windows, macOS, LinuxWork seamlessly with Raspberry Pi 5, Raspberry Pi 4 Model B, or Raspberry Pi 400 and Raspberry Pi OSDimensions: 51mm x 21mm x 1mmGPIO, ADC, UART, SPI, I2C of Raspberry Pi PicoNote: The photo shown is Raspberry Pi Pico W, and Pico 2W is similar.

Raspberry Pi Zero W  We have been carrying Raspberry Pi Zero W (Wireless) since 2017 and it is very useful for makers and students. It is a super low-cost single-board computer. It is cheaper than any official Arduino controller board with a 32-bit processor, and it comes with WiFi and Bluetooth. The new Raspberry Pi Zero W offers all the benefits of the Pi Zero v1.3 but with one big difference – built-in Wireless (WiFi and Bluetooth)! More specifically, this giant upgrade is the addition of a BCM43143 WiFi chip built-in to your Raspberry Pi Zero – just like the Raspberry Pi 3 Model B! Let's see the introduction from the Raspberry Pi Magazine team:  With BCM 2835 (32-bit ARM-based processor) SoC running at 1GHz, the Raspberry Pi Zero is faster than Raspberry Pi 1. With mini-HDMI, micro-B OTG USB, and the same 40-pin GPIO it still has great connectivity although you'll probably need some accessories to help you hook it up to your existing devices. The best part about all this is that the Pi Zero W keeps the same shape, connectors, and mounting holes as the Pi Zero v1.3. 99% of cases and accessories will still be fully compatible with both the Pi Zero W and v1.3 - though if you have a case with a metal top there might be some WiFi connectivity difficulties.  Soldering the 40-pin headers onto Pi Zero W is not everyone's favorite task, especially beginners. Some might not have the right tools to do it. And here you are the Raspberry Pi Zero WH, pre-soldered with 2x20 header pins at the factory directly from Raspberry Pi, UK. This will help in hardware prototyping and digital making, stacking with HAT and electronic parts. Raspberry Pi Zero 2 W  Raspberry Pi Zero 2 W, the most significant upgrade is the CPU. The new Raspberry Pi Zero 2 W comes with a Quad-core, 64-bit, Cortex-A53 CPU, clocked at 1 GHz. At its heart is a Raspberry Pi RP3A0 system-in-package (SiP), integrating a Broadcom BCM2710A1 die with 512MB of LPDDR2 SDRAM.   The new CPU+RAM package on Raspberry Pi Zero 2 W is from the Raspberry Pi engineering team, to understand more about the integration and why they choose wire-bonding instead of Package on Package (PoP) on the original Raspberry Pi Zero/W/WH, check out the post by Eben Upton (CEO of Raspberry Pi Trading). RP3A0 System-in-Package (SiP), by Raspberry Pi Blog Post There is a slight improvement in the wireless specification, the Bluetooth on Raspberry Pi Zero 2 W is upgraded to 4.2 from 4.1 on its pre-successor. Of course, it still preserves the IEEE 802.11 b/g/n WiFi and BLE. Besides the upgrade of Bluetooth specifications, the wireless circuitry is also shielded with a metal case for better RF compliance. Let's compare the new Raspberry Pi Zero 2 W with its pre-successor, Raspberry Pi Zero W:  Those highlighted in Blue Color texts are the major changes. From a single-core, 32-bit CPU in the original Raspberry Pi Zero W, we now get a Quad-core, 64-bit CPU! With this upgrade alone, there is a tremendous improvement. Booting into Raspberry Pi OS desktop GUI is 3X faster than the Raspberry Pi Zero W board. From our testing, using the 32GB MakerDisk preloaded with Raspberry Pi OS, Raspberry Pi Zero 2 W boots into GUI just within ~20 seconds while the earlier Raspberry Pi Zero W takes ~70 seconds. For single-threaded performance, it is 40% faster than earlier versions too. For multi-threaded, the quad-core performance is 5.2x faster than the single-core CPU. If you are a Raspberry Pi user, you might have noticed the Quad-core, 64-bit ARM Cortex-A53 CPU is also on Raspberry Pi 3 Model B:  And even it comes with a quad-core processor, the maximum power is still way below 5W, or below 1A of current. During idle (power up without doing anything), it consumes just 0.62W, which is just 124mA at 5V. Even under stress tests with active WiFi, the Raspberry Pi Zero 2 W consumes only 2.12W. That is only 424mA at 5V, still below 2.5W! Do check out the post by Jeff Gerling on his review of the Raspberry Pi Zero 2 W that also produces this power consumption chart:   Power Consumption Chart by Jeff Gerling With a careful look, we notice the PCB antenna on Raspberry Pi Zero 2 W has been improved to be similar to the Raspberry Pi 4 Model B's PCB antenna! This again will improve the wireless connectivity and data rate.  Thanks to Jeff Gerling, we get to know the WiFi speed improvement. This is the WiFi speed comparison by Jeff in his review of Raspberry Pi Zero 2 W: WiFi and Wired Speed Comparison of Raspberry Pi Zero 2 W vs Zero W, by Jeff Gerling Raspberry Pi Zero 2 W Specs:Processor Package: RP3A0-AU, SiP (System in Package) BCM2710A1 wire-bond with 512MB RAMProcessor: Broadcom BCM2710A1, Quad-core 64-bit SoC, ARM Cortex-A53Clock speed: 1GHzRAM: 512MB LPDDR2Built-in Wireless:WiFi: IEEE 802.11 b/g/n, 2.4 GHzBluetooth 4.2BLE (Bluetooth Low Energy)Antenna: Onboard PCB antennaMemory: micro-SDVideo output:mini-HDMIComposite Video (Test pads at the bottom layer of PCB)Multimedia:H.264, MPEG-4 decode (1080p30)H.264 encode (1080p30)OpenGL ES 1.1, 2.0 graphicsUSB Port: 1 x Micro-B USB for data and powerPower input:1 x Micro-B USB for power (no data), 5VDC5V and GND pins on 40-pin GPIO (unpopulated)Camera interface: CSI-2 compact camera connector (needs adaptor cable, 0.5mm pitch to pitch CSI)GPIO: WCH - Pre-soldered Color Coded 40-pin GPIO connector, compatible across all Raspberry Pi with 40-pin GPIOCompatibility of GPIO: Compatible with existing HAT add-onsSupported OS: Raspberry Pi OSDimensions: 65mm x 30mm x 5mm

DescriptionThis is a 3W high-power 850 infrared light, adjustable resistance. Comes with an onboard adjustable resistor, for controlling the ambient light threshold of toggling the infrared LED. It allows adding night vision function to RPi cameras. You can use a small screwdriver to gently twist the variable resistor and adjust the ambient brightness to your preference. This infrared LED is a perfect addition for projects that require night vision.The LED light board and the camera PCB bottom plate can be screwed together to use (no software control is required. The working mode of the light board is that when the light is dark, the LED light is automatically turned on, and when the light is strong, the LED light is automatically turned off. The adjustable resistance on the light board needs to be adjusted. Our default delivery is not adjusted. Because different user uses the infrared LED at different locations, it will automatically turn on when it is connected by default. If no adjustment is made, the LED light will always be turned on. Bear in mind that since it is always turned on, it heats up pretty easily. It is recommended to stick a heatsink at the back of the infrared LED, on the cooling area (gold plate).How to use:Connect the Infrared LED Board to the camera PCB with screws.The screw holes are used for both attachment and power supply.Adjust the adjustable resistor to set a proper ambient light threshold, which toggles the infrared LED automatically.When ambient light is lower than the threshold value, the infrared LED is on, vice versa.Note: The 3W high-power infrared LED might cause the Pi to increase heating, heatsinks are suggested. The ideal imaging distance is within 3 meters. When the distance goes up to 6 meters, the night vision camera can just capture blurry outlines.This 3W Infrared LED for RPi NoIR Camera Module is compatible with:Fish Eye Lens Raspberry Pi 5MP IR Camera3.6mm Lens Raspberry Pi 5MP IR Camera

The step-up topology operates from input voltages as low as 20mV.Using a small step-up transformer, the LTC3108-1 provides a complete power management solution for wireless sensing and data acquisition. The 2.2V LDO powers an external microprocessor, while the main output is programmed to one of four fixed voltages to power a wireless transmitter or sensors. The power good indicator signals that the main output voltage is within regulation. A second output can be enabled by the host. A storage capacitor provides power when the input voltage source is unavailable. Extremely low quiescent current and high efficiency design ensure the fastest possible charge times of the output reservoir capacitor. The LTC3108-1 is functionally equivalent to the LTC3108 except for its unique fixed VOUT options.The LTC3108-1 is available in a small, thermally enhanced 12-lead (3mm × 4mm) DFN package and a 16-lead SSOP package.Output Voltage (Switcher)LTC3108 Selectable 2.35V, 3.3V, 4.1V or 5VLTC3108-1 Selectable 2.5V, 3V, 3.7V or 4.5VApplicationsRemote Sensors and Radio PowerSurplus Heat Energy HarvestingHVAC SystemsIndustrial Wireless SensingAutomatic MeteringBuilding AutomationPredictive Maintenance
