MiniPiio L293D board v0.10

September 7th, 2012

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.
