After my ThinkPad keyboard project, I had surplus stock of F5502 QFN-48 chips, also because Element14 is having them on sale, so I made some breakout boards for them. I can't remember where I got the inspiration for the port and pins numbering from but I'm sure it was on this forum a few years ago. It should fit on a small breadboard though I haven't tested it yet. The boards include a BSL button as well as SBW lines (RTVG for Reset, Test, VCC, GND lines).
Rev. 1
Gerbers
Boards (DirtyPCBs sent me 20 boards of the design on the left so no resonators)
Rev. 2 - Include resonator, crystal + caps on 1 PCB and layout of via holes moved so it won't interfere with the silkscreen, width of board reduced
Front, Back renders
