P16PRO programmer for PIC16Cxx microcontrollers by Bojan Dobaj

For the power supply a universal AC/DC (3 - 12V) adaptor

can be used. The switch must be in position 12V. It is

recommended to change the capacitor inside the adaptor with

capacitor for a minimum 25 V. Check the output voltage

(unloaded), it must be at least 16V for PIC16C6x and

PIC16C7x and minimum 14V for PIC16C84.
