Arduino pro mini undershield

The cheapest Arduino clone on Ebay is probably the small Arduino pro mini clone. I've bought some pro minis on Ebay for less then 3$ a piece from a Chinese seller. It's a tiny board with an ATmega328 running @ 5V. It does not have an USB/serial chip, so you need your own USB to serial converter.

Getting ready for the service droid :)

So I've ordered the Dagu service droid :) http://letsmakerobots.com/node/38776

I'm getting the service droid with a Rover 5 (4 motors/encoders), 4 channel motor controller and Dagu Red Back Spider.

I already have a Rover 5 with 4 motors on which I use the 4 channel motor controller and Red Back Spider. I'm powering everything from a 2S Lipo (3000mAh). You can see it here: http://letsmakerobots.com/node/31410 or on my blog: http://www.bajdi.com/category/rover-5/

On my current Rover 5 the 2S Lipo feeds 3 devices:
