Adafruit 2455 - PiTFT 2.4" HAT Mini Kit - 320x240 TFT Touchscreen

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A. Typical efficiencies of 85% to 95% make this regulator well suited for high-power applications like powering motors or servos.

High-voltage high and low side driver, STM, SO14, RoHS

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 9 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.

A4988 Stepper Motor Driver Carrier with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Pololu 2980

Ethernet board with mini SD card slot based on W5100 controller.
