Hi guys,

if I want to use my own MCU in place of Volumite, what do I need to know? What do you interface with on the I2C Relay Driver board? Is it a PIC with your own firmware on?

Thanks.

The I2C Relay Driver has a Microchip MCP23008-E/P I2C port expander, that drives a ULN2803 transistor array.
