This is Sparkfun part DEV-09709.
This is a small prototyping shield for the Arduino Pro Mini. If your project requires just a little bit more space for your external circuitry, this might be a perfect addition. 38 unconnected PTHs are provided for your prototyping needs.
The shield fits the small form factor of the Arduino Pro Mini - connecting to the 'top' four pins on each side of the Mini ('GND'-'TXO' & 'VCC'-'RAW'). There are small buses for VCC, GND and RAW. In addition to the power buses, the serial pins are also broken out on the shield. The analog and digital pins are not broken out on the shield.
