Connection to the Indesit ARCADIA PCB:
The following is a variant of connecting ARCADIA PCB to a computer via the USB Elinv Prog programmer.
Note that the output of the Elinv Prog is only 3.3 Volts. This voltage is insufficient when connecting to the specified points of the board. In this case, you need to arrange the board power separately.
For example, on a 4.5-volt battery, as shown in the figure below or from the 9-volt battery.
You can also use the positive output from the USB port of the same computer.
In any case, you can not use this connection to power the module from the 220 volt network!
The following photo shows the connection of the ARCADIA module via USB Elinv Prog, powered directly from the +5 USB port.
