Arduino-compatible RS027 Mini Driver: for your DC and servo motors

The RS027 Mini Driver was initially designed for controlling two brushed DC motors. It’s compatible with the Arduino development environment and an Arduino NG board (or older, provided it’s compatible with the ATmega8A microcontroller).

Each motor can be controlled with currents up to 2.5 A. This board also allows you to control up to 8 servos and/or sensors by using its lateral outputs (D2, D3, D4, D5, D6, D11, D12 and D13). Plus you have 6 analogue inputs.

Finally, it’s worth pointing out that by removing the 4 jumpers allotted for the two motors you’ll free up 4 additional digital I/Os: D7, D8, D9 and D10.

Powering with the ATmega8A controller

There are 2 ways of powering your motors, servos and sensors using the ATmega8A controller:

  • The +5V mode allows you to power your sensors and certain servos (provided they’re not too power hungry) from the 5 V regulator;
  • The +Bat mode allows you to power your servos and motors directly from the battery, for currents of up to 9 V.
