This add-on board enables a Raspberry Pi (Model B+ or newer) to drive a pair of brushed DC motors. Its dual TB9051FTG motor drivers operate from 4.5 V to 28 V and can deliver a continuous 2.6 A (5 A peak) per motor. The default pin mappings make it easy to get started using our provided software, but the board also exposes most of the driver chips’ I/O pins for more specialized applications. This version ships as a partial kit; all surface-mount components are installed, but the included through-hole connectors are not soldered in.

Notes:

1
Without included connectors and mounting hardware.
2
Operation from 4.5 V to 8 V reduces maximum current output.
3
Transient operation (< 500 ms) up to 40 V.
4
Typical results at room temperature with VIN > 8 V and both channels running 90% duty cycle. Operation from 4.5 V to 8 V reduces maximum current output.
5
On motor voltage only; logic voltage does not have reverse protection.
