Electric Dollar Store

This shield connects the I2C bus on your Arduino to four Electric Dollar Store modules and three I²C breakout ports. Each is supplied with GND, 3.3 V and the I²C signals. The shield has four slots for Electric Dollar Store modules, all on the same I2C bus, plus breakout headers for additional I2C modules. With the AHDR kit, it makes a complete Arduino shield. Or you can use it stand-alone as a four-way module mounting panel.
