Chip con supporto nativo di:
  - circuitpython
  - usb HID
  - bluetooth HID
  - pin analogici con resistenze pullup/pulldown
Esempio: nrf52

  * Connettore USB type-C
  * Giroscopio mpy6050 attaccato al chip tramite I2C
  * Pin per batteria litio ricaricabile tramite USB
  * Bottone boot/reset per debug?
  * Switch on/off
  * Led rgb con controllore neopixel
  * Connettore con 4 pin (jack/usb):\\ - 3 pin analog input con una resistenza pull down\\ - 1 pin 3.3 volt con resistenza analoga

Ai 4 pin saranno attaccati 3 touch switch,
la corrente deve poter attraversare un dito o una lingua senza provocare pizzicore
