I recently finished 3 PCB's for sharing at OSHpark.
-
Mini Stick - An Ardweeny DIP module inspired by CrossRoad's discussion with LarryD and WestFw's suggestion in the discussion.
1284P top mount card - Microcontrollers - Arduino Forum -
Radio Nano - A Nano style DIP module with nRF24L01+ interface.
-
In-between shield - Inspired by the go-between shield, https://www.sparkfun.com/products/11002 ,
this in-between swaps UNO I/O pins without soldering.
These are all through hole boards for DIY makers. If anyone is interested in making them or selling them in kits, you can order low cost PCBs from OSHpark OSH Park ~ Shared Projects by Firebirduino, or Iteadstudio http://imall.iteadstudio.com/open-pcb/pcb-prototyping.html depending the PCB size.
