A year ago, I needed to prototype a design which used PIC18F8722. It’s a nice microcontroller with plenty of ROM, RAM, and peripherals. It comes in 80 pin 0.5mm pitch TQFP package. To use it in prototyping, I designed breakout board which holds the micro, crystal, and filter and decupling capacitors. With time, I changed the layout to accommodate other PICs in the same package and recently made a variant which takes any 80-pin PIC in TQFP-80 package in production, at the time of this writing. This includes:
- older PIC18Fs
- newer J-series PIC18s
- “Classic” dsPIC30
- J-series dsPICs
- PIC24s
