The Key Lime Pi kit breaks out the Raspberry Pi's GPIO connector, adds eight 10-bit analog inputs, converts the Pi's serial interface into a standard FTDI connector and allows for external power headers to be added if desired (standard 0.1" pin headers and JST-PH vertical header).

There is a kit version of this board includes an enclosure to mount the board on. The Key Lime Pi Scorpion Kit includes both the Key Lime Pi and the Scorpion case

Specifications Top

Analog readings are as fast and accurate as possible, thanks to the Pi's SPI interface (hardwired to CE0), a proper ground plane and a stabilized ADC power supply. If more than eight analog inputs are needed for a project, chaining to another 'Nwazet Key Lime Pi' board is possible by interconnecting the GND, MOSI, MISO, SCLK and CE1 lines with jumper wires.

For prototyping, the 'Key Lime Pi' board maximizes the real-estate available on small breadboards by hugging the center divider, leaving four rows out of five available for wiring.

For embedding a project into a permanent fixture, the board features three mounting holes, placed on a standard 5mm grid.
