SimpExp

From JopWiki

is a simple bread board with power regulation and a connector for the serial line.

[edit] Power Supply

The SimpExp requires a DC power supply of about 5 or 6 volts. To provide power, you can use one of the power supplies offered by JOP.design, or you can obtain one from your local electronics supply store. For example, Radio Shack offers a universal power supply. It includes six DC barrel plug adapters; the one for the SimpExp is Type H.
