Part description
This part controls one or more RGB LEDs according to commands coming in through an I2C interface.
External interfaces
JP01 |
6-pin AVR ISP connector |
JP02 |
LED connector |
JP02.1 |
LED common anode |
JP02.2 |
red cathode |
JP02.3 |
green cathode |
JP02.4 |

JP03 |
Power and data connector |
JP03.1 |
Vcc (+5V) |
JP03.2 |
GND |
JP03.3 |
I2C SCL |
JP03.4 |

Notes
Connect JP03.3 to JP03.4 with a jumper before providing power to the device to enable test mode. In test mode, colors are automatically cycled continously without data input. To disable test mode, first disconnect power supply, remove jumper, connect to master device.
- The interface electronic inverts the output state of the microcontroller. This has to be taken into account when developing firmware for the microcontroller.
