Adam Ward of Wardy’s Projects has developed his own Parallax Propeller dev board and is sharing the files under the CC-BY-SA 3.0 license on Github.
Protopeller is a small, simple PCB design that provides a Propeller chip
with a regulated on-board power supply, an optional external crystal and
breakout connections for all of it’s 32 digital GPIO pins. There is also
an EEPROM chip to store the firmware for the Propeller to run, and an
FTDI header connector to allow the firmware to be uploaded from a PC.
Thanks Adam!
