How to connect an ESP32 to my Proffieboard 3.9?

Hey folks!

I want to connect my ESP32 to my proffieboard so It can read the IMU data. Which pads on my proffieboard can I wire my ESP32 to?

Additionally, can I power the proffieboard with 5 volts since the ESP32 requires such as well?

Serial port.

Note that ProffieOS does not feed out IMU data to the serial port by default, but would be relatively easy to add something that does that.

The Proffieboard can handle 5 volts.

Thanks for your reply!

My goal is to use the esp32 to log and timestamp the events from the Proffieboard, essentially recording the light and sound pattern generated by movement, and then send to a second saber where the esp32 injects that recording as input into a Proffieboard to playback the recording through the speaker and led. Is the IMU the best way to record this information?

You probably want to log IMU events, but you also probably want to log button events.
(Or, you could maybe log SaberBase events see common/saber_base.h)
Either way you’re going to need to do some coding to extract, send, receive and inject these events.

Regardless of what type of events you extract, the serial port is almost certainly the way to talk to the ESP32.
