** UPDATE: You’ll be able to get these boards soon at tindie.com in the DTronixs store
I’m really pleased with the design of this MiniPiio board.
It fits it’s purpose perfectly. A small 170-pin breadboard you can plug directly onto your Raspberry Pi and have access to the GPIO pins from the RPi’s Expansion Header. You can’t see it but it has the option of a 3.3V voltage regulator to give you more current for the 3.3V for use in your circuit design.
The schematic is here:

MinPiio (or MiniPi I/O) is a name given to a number of small add-on boards designed for use with the Raspberry Pi. Each board measures a small 50mm x 40mm, connects to the Raspberry Pi’s expansion header and does a specific type of I/O.
Boards being built as we speak include a RS232 interface, mini prototyping board, 16ch Digital I/O board and a high current Digital Output board. Other boards in the pipeline include a CAN Bus interface, RS485/DMX512 Interface, Relay Board and a thermocouple board.
