Here’s the second of the new Raspberry Pi MiniPiio add-on boards.
This is a DC Motor controller using the venerable L293D from ST (and others). The L293D is dual H-Bridge driver capable of driving 36V DC and 600mA per H-Bridge.
The board was designed in Design Spark PCB and the schematic is here.
Here’s the L293D board fitted to a Raspberry Pi:
and here’s the L293D and RPi driving a pair of small DC motors. Hope fully this will be a small robot in time for e-day the Newcastle Maker Space is talking part of at Gateshead Central Library on 29th September.

Not at the moment, it’s still be tested, but I’m pleased to report that PartCo in Finland are stocking some of the other boards

Hi!, we’re interested in making a RPI Shield to interface it to our Aisoy robot’s head. Do you customize these shields?

Hi Diego
I’m not familiar with the Aisoy but I’ve a expander board that allows for two MiniPiio boards to be connected to the RPi
