This is a breakout board for 0.05" (1.27mm) pitch parts so that they may be connected to a standard 0.1" (2.54mm) pitch breadboard.
It was originally designed for use with the Olimex iCE40HX8K-EVB. This board uses a series of 40 pin IDC cables with 0.05" pitch which is great from the perspective of maximizing the footprint of the development board... it's sub-optimal for any peripheral development. Additionally, this board should be usable for other projects with similar footprint needs.

To build this board you will need the following:
| Part # | Quantity | Description |
|---|---|---|
| 2x20 Pin Header | 1 | 2x20 0.05" (1.27mm) Pin header (male or female depending on need) |
| 1x20 Pin header (male) | 2 | 2x20 0.1" (2.54mm) Pin header (male) to be connected to breadboard |
The 0.05" pin headers can be sourced from a number of locations:
The 0.10" pin headers can be sourced from a number of locations:
The board is currently shared on OSHPark and can be ordered. The cost is $9.95 (USD) with a turnaround time of approximately 15 calendar days.
The Olimex iCE40HX8K evaluation board can be purchased through Olimex.
