PIC18F2550 / PIC18F25K50 board
Posted: Thu Nov 10, 2016 12:37 am
I built and assembled a small prototyping board for PIC18F2550/PIC18F25K50. The PCB has been produced by SeeedStudio (excellent results), and I assembled first prototype by hand (quickly).
The board can be plugged directly on a breadboard, can be programmed using any PIC programmer via the 5 pin header.
Almost all pins are exposed, and I added two jumpers to make it possible to physically connect/disconnect two LEDs on PIC pins.
Another jumper provide the possibility to pull-down one pin in order to trigger the USB bootloader (if you prefer avoid an external programmer).
I didn't assembled the crystal on my board because I'm trying PIC18F25K50, and I want to check the possibility to do USB using internal crystal only.
I'll post the whole project, schematics and gerbers, and example souce codes (using Microchip C, Swordfish Basic) in few days.
Here some photos of the board
