This MOSFET power module is designed to let your 3D printer handle a heated bed (Hot Bed) with higher power demands—supporting currents up to 25A. Most 3D printer mainboards are limited to around 15A, but by using this external module, you can safely drive more powerful beds without overloading your printer's internal electronics. It supports both 12V and 24V heated beds. For high-current applications, using 24V is recommended, as it draws half the current for the same power output compared to 12V—making it more efficient and reducing cable heating. This module adds a layer of protection to your printer’s control board while also improving power delivery to the heated bed.SpecificationsMOSFET Type: High-power N-channel MOSFET Max Current Load: Up to 25A (with proper cooling) Operating Voltage: 12V / 24V DC Control Voltage: 5V (compatible with most 3D printer mainboards) Trigger Signal: Low-level active (connects to printer’s heated bed output) Voltage Drop: Low RDS(on), minimal heat generation with good cooling PCB Size: Approx. 60mm × 50mm Connector Type: High-current screw terminals Application: Heated bed power expansion for 3D printersWiring Diagram

This FPV Pan/Tilt Camera bracket is designed for 9g–12g servos, such as the SG90 with plastic gears. It weighs just 17 grams and is made with a precise build, offering a stable structure without play or wobble. It also includes a clip for organizing servo wires. Note on Installation: For the top servo mount, the servo arm may need to be slightly trimmed to fit properly. For the base servo, you'll need to modify the servo arm as well—usually by cutting off the round-hole side or trimming the arm to fit. This Pan/Tilt is specifically designed for 28×28mm camera modules. It is not compatible with larger 32mm or 38mm camera modules. Please double-check your camera size before purchase. Note: Servo motors and cameras are sold separately

This module features two 10K potentiometers combined into a single unit. In most cases, you only need three connections to your Arduino: VCC, GND, and Output A or B. It’s ideal for stereo audio volume control, letting you adjust both the left and right channels at the same time—without mixing them together. Unlike rotary potentiometers, slide potentiometers offer a more intuitive control experience for some applications. They can make it easier to understand directional input, such as up/down or left/right, by giving a clearer sense of movement and position.SpecificationsSize: 90mm (L), 20 mm (W), 30mm (H) Knob height above pcb 26.7mm Slider Maximum displacement: 60mm Pin pitch: 2.54mm PCB Color: Red Voltage: 3.3 V, 5 V Output: Analog Voltage from 0.0V to VCC Resistance: 10 k Type: Linear
