   Attention! The COM port has no output for powering any devices (unlike USB). Because the signal outputs of the COM port are used to power the module, depending on your computer, the current may not be sufficient to power the module. 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 a self-made programmer for the COM port, powered directly from the +5 USB port.
