1.PWM signal output working mode:red LED indicates PWM signal output, 11 channels Totally.
2.S-BUS signal output working mode: blue/purple LED indicates S-BUS signal output, 12 channels totally.
S-BUS and PWM signal working at the same time. S-BUS signal channel(3 pin of row 11) output 12 channels S-BUS signal, PWM signal channels(3 pin of row 1 to row 10) output CH3 to CH12 PWM signals, but 12 channel in total. How many PWM signal channels you can use depends on how many S-BUS signal channels you have used(e.g: you have use 4 S-BUS signal channels, then you have 8 PWM signal channels to use).

PWM signal working mode:
