Modern microcontrollers like the RP2040 and ESP32 are truly a marvels of engineering. For literal pocket change you can get a chip that’s got a multi-core processor running at hundreds of meg… ...

Applications First of all, the Pendrive S3 is simply a development board with ESP32-S3, which can be programmed from Platformio, Arduino IDE and CircuitPython.

Their ESP32-powered CircuitPython solution takes the sensor output of a given bike or scooter (throttle, cadence, or torque) and translates it into the inputs the controller uses to set the motor ...
