Adafruit I2C to 8 Channel Solenoid Driver

Solenoids are a little like cats: if your project has one solenoid you'll probably stick with just one and in such cases our single MOSFET driver will work well. But if you have more than one solenoid, it's going to be anywhere from 2 to 24. Why? Maybe people just love their purring clicky-clacking. And driving a lot of solenoids is kind of a pain: they all need drive transistors and flyback diodes and then a common power source. That's why we designed the Adafruit I2C to 8 Channel Solenoid Driver featuring an MCP23017 GPIO expander to make eight solenoids at a time easy and solder-free.
