Arduino Nano to PIC40/28 PIN development shield is an extension for Arduino Nano. This project is useful to create many projects using PIC40/28PIN shield published on electronics-lab.com, refer to schematic and connection diagram to use this shield. Two on board regulators are provided which outputs 5V DC and 3.3V DC, this dual supply helps many projects which need dual supply. Jumper J1 is for supply selection VCC To 3.3V or 5V, diode provided at input of regulator for reverse supply protection. Not populated J4, Close J3 to supply 5V to Nano.
