I are interested in increasing the memory in the CPX (and the PyBadge too). For the CPX, I found a pin-to-pin compatible chip with larger size (https://www.digikey.com/en/products/det ... 10/7100880). The footprint seems a bit larger than the memory chip in the CPX, but with a little elbow grease it just may fit.
My questions is, assuming the soldering/desoldering goes well, does anything in the firmware needs to be changed to have access to the larger memory, or would it "just work"?
Thank you!

Re: Increasing the board's memory
It depends on what firmware you want to use. For CircuitPython you'd make a minor change to the CPX build to have it use the large memory. I did that way back when with a Feather M0 Express: https://circuitpython.org/board/feather_m0_supersized/ http://daveastels.com/feather-m0-expres ... izing.html. Compare https://github.com/adafruit/circuitpyth ... supersized to the original https://github.com/adafruit/circuitpyth ... m0_express.
