Board chain: USB <> BLE <> Motor fader

[Thorsten-Behrens]

Dear Pieter,

what is the best platform to ask questions regarding Control Surface?

In case it's here (if not ignore): What is the best chain to control a motorfader via ble?

If I understand correctly for native USB support one of the following boards is required: Arduino Due, Arduino Leonardo, Arduino Micro, Arduino Nano 33 IOT, Arduino Zero, Arduino MKR Zero, Arduino MKR1000 ...

For BLE transfer two ESP32 are required, as the Arduino Nano BLE is not supported.

For Control Surface Motor Fader an Arduino UNO or Nano are equired.

So a possible chain would be:

PC side: Arduino Micro ESP32

Control Side: ESP32 Arduino Nano BLE

This is four boards. Is there any option to reduce it to three or even two boards?

Thanks a lot in advance! Thorsten
