Well for one, you will have a hard time running Linux with 32k of RAM… For Linux to be viable you need at least 2MiB, 8MiB to do anything useful. Microcontrol

Well for one, you will have a hard time running Linux with 32k of RAM… For Linux to be viable you need at least 2MiB, 8MiB to do anything useful. Microcontrollers that are used for sensors and controller devices don't have that much memory. High end MCUs will have 256k RAM/1024k ROM, but cheaper/lower power devices will have much less.
