I2C-Bus LED-Bargraph
The I2C Bus LED-Bargraph uses a PCA8574A for direct output of 8bit parallel which drive the 8segments of the bargraph. Multiple I2C adresses are configurable. The board supports 100kHz standard I2C mode and 400kHz Fast-I2C-ModeSuitable for Arduino, Raspberry Pi in conjunction with CoPiino or any other I2C microcontroller project.
