2.1 General Description

The Designer Systems pHAT-RV is a fully featured remote vehicle driver solution with four [4]

unipolar stepper motor drivers, four [4] servo motor drivers and Lithium battery power

control features. Specifically designed for the Raspberry-Pi Zero (other Raspberry-Pi boards

fully supported) the pHAT-RV features Lithium battery power regulation, a battery charging

system and high speed I2C communication for easy project integration.

pHAT-RV supports the majority of analogue servos and unipolar stepper motors (selectable 1

or 2 phase) and also provides global activation of new motor positions & movement complete

registers for superior control. Motors can be fully speed controlled, reversed, started/stopped

and stepper motors stepped with up to 65535 steps.

pHAT-RV provides a 5V @ 1A power supply (link selectable) to power the connected R-Pi Zero

and features an on-board Lithium Polymer charge controller that can charge the battery at 1A

(2000mAh min capacity) from an external 9-12VDC power adaptor (not supplied).

Due to compact form factor, ultra-low power consumption and extended temperature range,

pHAT-RV is a best choice for a wide range of robotic applications.

The module fully complies with the RoHS directive of the European Union
