The Surface Mount Shield Kit breaks out the connections on the Digispark development board and provides a small surface mount soldering area for building custom circuits.
The SMT pads on this board are 1.27x2.54 (50x100mil).
This is an unassembled kit and requires basic soldering.
Use of it requires surface mount soldering.
This is designed for use with the Digispark development board, which is not included.
