# RoboHat
|
||
|
|
|
||
|
|
The RoboHat is a complete robot controller for small robots. It has 2 full H-bridges using DRV8833 for up to 1.5A per channel, a 5V switch-mode regulator to generate the 5V for the Raspberry Pi, 6 buffered inputs that can accept 2.5V to 5.5V and convert to 3.3V and 4 outputs driven up to 5V. All the I/O is via GVS (Ground, Volts, Signal) 3-pin terminals so it is easy to plug in 3-pin sensors or small servos directly. There is also a connector plug in an HC-SR04 ultrasonic distance sensor with the necessary circuitry to read the value using a single GPIO pin.
