Description
This I2C relay controller is compatible with all computing platforms.
This controller consists of one relay. The on-board relay is controlled by a MCP23008 using GPIO0. The remaining 7 GPIO pins (GPIO1:7) are available for general purpose TTL/CMOS Input/Output applications under software control.
Controlling the on-board relay is easy: simply set GPIO0 as a Digital Output. Next, set the on/off status of GPIO0 to activate the relays. One LED indicates the status of the on-board relay.
External devices may be wired to turn on when the relay turns on. Optionally, external devices may be wired to turn off when the relay turns on.
This controller includes an on-board I2C expansion port, allowing an easy pathway to expansion for controlling more relays, reading sensors, or expanding to any I2C device we develop in the future. Up to eight MCP23008 based devices may be connected to a single I2C port. The start address of this device is set using 3 on-board jumpers.
