I2C Relay Board 8-Channel using MCP23008
Brainstorm Technologies has developed the 8-channel I2c Relay Board, It is a fully optically isolated relay board. The microcontroller side and the relay coil power supply side are fully isolated using optocouplers, Even the GND planes of both the sides are separate to provide full isolation. This board is using the MCP23008 IC to make it I2C ...
