I2C-Bus Power-OutThe I2C Bus expander uses a PCA8574A for direct output of 8bit parallel. The onboard power driver ULN2803A is capable of driving 500mA per output. Multiple I2C adresses are configurable. The board supports 100kHz standard I2C mode and 400kHz Fast-I2C-Mode
Suitable for Arduino, Raspberry Pi in conjunction with CoPiino or any other I2C microcontroller project.
