I know Lovense Lush uses a Nordic nRF51822 microcontroller, this doesn’t run a full OS normally. It runs ARM machine code directly, usually programmed in a C variant in something like Keil. They provide an SDK with an Arduino compatible platform, so it might even just run Arduino. No idea if someone analysed the software on those microcontrollers as it’s pretty niche and the code inside is probably super simple. The microcontroller is way overpowered for what it does, but it isn’t that overpowered that it could run a full Linux stack.

Are you like an open buttplug dev or somwthing?
