From the project
PCBs and breakout boards, designed by the MobiFlight community
The board uses XH JST connectors for the individual LED's and for connecting to the Prototyping Board. Four 8 bit output shift register with integrated LED driver are daisy chained. Each group of 8 LED's can be dimmed via PWM input and the max. brightness can be adjusted via a potentiometer.
For more information on how to configure the board with MobiFlight, check out the MobiFlight Connector documentation.
