PIC18F4550 Development Board



A simple PIC development board


Pic Board


This is a simple 40 pin PIC development board as described in RadCom for November 2009. It is designed for a PIC18F4550, but it will work with other 40 pin PICs like the PIC16F877A. It has no bells & whistles attached. No buttons, LED, LCD ICSP etc. All of the PIC pins are easily accessible so that you can add any features you need. This board has been tested with the Vasco PUF and the Pinguino USB bootloaders.

Note the two 805 surface mount 100nF decoupling capacitors. The red wire was used to steal +5V from the USB cable. This is probably not a good idea unless you have a 500mA fast fuse in the circuit.
