CH#1
Connection to the port expander
can be set per app, whether static,
flashing or flickering
Q1
4A MOSFET
electronic switch
CON#PWR
3Pin connector
Connection of power supply / step

CON#CH1
JST-XH2
connector for LEDs, etc.
VCC1
V
Power supply voltage
SW#CH1
GND
GND - switched by Q1
If the channel is activated via app, the mosfet Q1 switches the connection CH1-1 to GND.
This will route power supply voltage from CON#PWR (VCC1) to CH1-2 through the connected load.
The pin assignments for channels 1-10 are identical to those on the deAgostini board.
