I've been wanting to cobble together a phone using a microcontroller hooked up to a 4g/5g module. Anyone have a module recommendation? I think everything currently available on sparkfun and adafruit won't work for me.
Many 4g/5g modules are basically stripped down/headless smartphones in themselves, running Linux + modem firmware, etc. You don't need the microcontroller, you just need to patch the firmware.
Yes. I was looking for an answer along the lines of a particular model from Telit/whoever. I'd rather use the external micro to control the module with AT commands.
