USB PIC Programmer PICKit2 Modified Circuit Diagram The mini USB connector is replaced by commonly available USB-B connector. Bipolar transistors used in Original PICKit2 are replaced by MOSFETs, thus minimal additional components are required.ĥ. The Programmer-to-go function is not an important feature for a electronics hobbyist.Ĥ. Two 24C512 EEPROM’s used only for programmer-to-go function in the Original PICKit2 were omitted.

It supports only 5V PIC’s, thus 3.3V devices a small additional circuit to convert 5V to 3.3V.ģ. ICSP to ZIF converter is added for easier programming, thus we can use ICSP or ZIF socket according to our needs.Ģ. The main differences between the modified PICKit2 and Original PICKit2 are:ġ. We have simplified the hardware schematics of PICKit2 by removing all unnecessary devices from it and ICSP to ZIF converter is also added for easier programming. Through this any one can add features, fix bugs and modify source code.ĭocuments and other supporting files of PICKit2 are available at Microchip’s Website.

Since it is a first release, Microchip published all the resources of PICKit2 public, which includes hardware schematics and all source code of softwares used. It is a USB based ICSP (In Circuit Serial Programming) programmer. Microchip’s PICKit2 is much more comfortable,reliable and powerful than the other programmers that we can find all over internet. 1.1 Substitutes for Unavailable Components.1 USB PIC Programmer PICKit2 Modified Circuit Diagram.
