- I2C commands for turning all relays off or on.
- Two I2C addresses
- 0x6D (Default)
- 0x6C
- I2C address is software configurable.
- All commands are listed in the example code.
- Screw Terminals
- 26-14 Gauge AWG wire

Revision Changes: The latest revision includes the following updates.
- Included a normally closed jumper for the power LED.
- Switching regulator in place of a linear regulator.
- The switching regulator is much more efficient; no external cooling needed when powering four relays at once.
- Improved circuitry around the relays.
- An issue where relays on certain boards in v1.0 didn't switch completely when actuated has been resolved.
