That’s interesting. I wonder what the protocol is. Probably a simple polling of registers. There didn’t seem to be an interrupt pin exposed.
There is similarity with the riban modular revision 1 panels which have 8 knobs or buttons & 8 buttons with all 16 having individually accessible RGB LEDs. This board is a bit cheaper though.
I wonder if there is benefit in making the riban modular panels able to interface with Zynthian? Maybe a USB-CAN interface.
This guy made an Arduino firmware for MIDI over Bluetooth for this device

Interesting… I could implement my own MIDI controller based on Arduino Micro.
You could use one of many 32 bit dev boards, and use Opendeck on it GitHub - shanteacontrols/OpenDeck: Software and hardware platform for simpler building of MIDI controllers.
I don’t know this OpenDeck… I’ll watch it right away… thanks
