Few month ago I wanted to try to write software for Microchip PIC16F883 microcontroller and I couldn’t find simple development board for it. And so I made my own.
It took me a couple of hours to design the board in Eagle and a couple more hours to make it with toner transfer method and solder it.
This development board is as simple as it gets. Just PIC16F883 controller in SO28W package, linear regulator with two selectable voltages 3.3V and 5V. Bunch of pinheaders connected straight to the MCU I/O pins, pinheaders for VCC and GND, and programming port.
Yeah, I know. I should’ve made a silkscreen on top of the board and not do that with permanent marker. But anyways, it’s not a big deal.
