This module features a fixed-gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This low-brightness version draws an average of 8 mA at 5 V and has a typical sensing range up to approximately 12 inches (30 cm).

Gravity: 360 Degree Hall Angle Sensor is a rotation angle sensor measuring a value in the range of 0-360 ° with an analogue output, powered by 5V. DFRobot SEN0221

LCD TFT display with a diagonal of 2.4 "and a resolution of 320x240 pixels. Equipped with a resistive touch panel and microSD slot. Designed for use with Feather series plates. Adafruit 3315

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40V and efficiently reduces it to 5V with an available output current of around 15A. Typical efficiencies of 80% to 95% along with its high current capabilities make this regulator well suited for powering large loads. Pololu 2881
