Clem,

My main plan is to help other people hook up 5V parts to their Raspberry Pi, I designed the card because there are a lot of posts out there with people who want to hook up five volt parts to their Raspberry Pi and the typical response is "just hook up some voltage translators", etc. Plus, I really liked GVS shields for the Arduino since they bring along power and ground with every signal line. They make it easy to hook up external parts. So I put the best of both worlds into this card.

Features

All Raspberry Pi I/O lines

8-bit bidirectional 3.3V to 5V level translator

Fuses on 3.3V and 5V power lines

All of the Raspberry Pi I/O connections are brought to GVS connectors. This is:

(8) GPIO lines on GVS connectors

(2) SPI interfaces (can be configured as 5 GPIO lines)

(1) UART interface (can be configured as 2 GPIO lines)

(1) I2C interface(can be configured as 2 GPIO lines)

The silk-screening doesn't give all the labels for the pins.

I would strongly suggest you use a slightly higher connector to clear the RPi hardware.

Many of the other boards that were snug fit, are only useable on the version they were designed for, rather than universal, and that becomes annoying.

It looks like your funding goal is met, so they should be around.

What plans do you have for this board?
