7") D24V10F5 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 5V while allowing for a maximum output current of 1 A

one-cubic-inch ultrasonic sensor module

Pi 2 or Pi 3 that lets it easily control a pair of bidirectional

These regulators can typically support continuous output currents of over 2 A

Pololu RC Switch with Relay (Assembled) hub-module where our original beacons wereThis product consists of a single pole, double throw (SPDT) power relay and a control circuit that measures incoming radio control (RC) signals, making it easy to control large, electrically isolated loads in RC systems. Example applications include using extra channels on an RC receiver or servo controller to turn on lights, motors, or irrigation valves. The RC switch is available pre soldered or as a partial kit that allows for greater application
