Hi everyone,
I am seeking for a little advice here...
I have an already finished project of a gaming handheld driven by a RP2040. Unfortunately, the RP2040 struggles to deliver the necessary performance.
Now, I think the Teensy is able to deliver that performance. However, since a Sega Genesis emulator is supposed to run, a whole ROM needs to fit into the flash storage. The Teensy 4.1 features enough storage. However, it is too tall to fit into the already existing case. The Teensy 4.0 on the other hand has a perfect size but the storage is just too small and an external flash chip tied via a (single) SPI interface might create a bottleneck.
Now, I was wondering if it was "safely" possible to cut off the lower part of the Teensy 4.1 board, i.e. the part with the SD card reader just beneath the row of holes (beneath hole 27 resp. 38). When I say "safely" I mean "are there any vital traces that are needed for the board to function OR would the cutting - if done properly - only imply to lose the ability to use the SD card reader and the expansion pads for PSRAM/more flash"?
Any advice is highly appreciated. Thanks in advance.
