Maybe my response comes like 'mustard after the meal' but anyhow. I just got a FACES set delivered. Using the M5Burner I flashed the latest UIFlow firmware.
Using the Thonny app (under MS Windows 11) I was able to use REPL.
Two negative impressions with Core2 and FACE-RFID:
When booting the Core2, it creates strange noise through the speaker for about 3 seconds
When off, there is a constant quiet noise through the speaker when USB is connected
