  The question is why a disposable vape needs a high performance 32-bit 24 MHz ARM MCU. What exactly does it do that can’t be accomplished by an 8-bit microcontroller.

    the fancier models come with screens and lite OSs now where you can do useless stuff like set lights and track puffs and what have you

  Ionescu decided to use the chip’s ability to handle the old Serial Line Internet Protocol (SLIP).

  With it, he turned the unit into a very basic 56K modem equivalent. He then added uIP 0.9 code to enable TCP/IP communication and web serving.

  Hah, cool. I was wondering if it has WiFi, serial stuff makes more sense.

  The ecig waste is tragic though.

    The MCU only has 3KB of SRAM so probably not. I think you need at least something like a Pi Pico or an ESP32 for that.
