I/O Expander Kit
The Expander Shield Kit allows you to build a Digispark shield which connects a PCF8574P Remote 8-bit I/O expander IC to the Digispark development board. It communicates with the Digispark over the I2C bus and provides 8 more digital i/o pins that can be controlled by the Digispark.

This is an unassembled kit and requires basic soldering. This is designed for use with the Digispark development board, which is not included.
