just noticed that on this PCB the D16 pin is brought to place with unpopulated something possibly third LED. So if one would sacrifice 2nd LED there would be 2 pins D17,D16 for I2C to possibly add something or use it as serial console.
BTW I flashed Espruino over SWD to this and had my first NFC experience with Espruino, it works quite well :-) I even tried WebNFC in Chrome on Android and it worked too. However for some reason the Samsung Internet browser (based on Chrome too) does not work. I see no error but it does not get any NFC data when I tap it and also it does not ask for NFC permission like Chrome does.
