Hardware Modifications

On the bottom side of the PIC-IoT Wx board, there are two cut-straps as shown in the figure below. These are intended for current measurement purposes. Do not leave these unconnected as the microcontrollers might get powered through the I/O’s.

The 5V supply to the mikroBUS socket is connected by default. To remove 5V from the socket, desolder the 0-ohm resistor (0402) below the 5V text, as shown in the figure below.
