The DI6acDQ6rly I2C-HAT is a 6 isolated digital input channels and 6 relay output channels Raspberry Pi add-on board that uses the I2C bus for communication. The input channels can be used as edge counters, every input channel has an two 32-bit counters attached, one for counting rising edges and the other for counting falling edges. The DI6acDQ6rly also has 6 LED indicators for digital inputs status monitoring and 6 LED indicators for power relay outputs status monitoring.
Users can stack up to 16 DI6acDQ6rly I2C-HATs on one Raspberry Pi by using the on-board address jumpers to select a unique I2C bus address.
