    Ah! No wonder I thought the battery went flat so fast. Thanks for the piezo hint (I tried playing a beep when the button was pressed but I reset the pin after the button is depressed).

    Ah, this is something I'd like to try as well (NFC) :D Sadly I misplaced my puck.js and while I can prototype on the pixl.js it's a bit too bulky to try and place on my keychain.

    Nice to know that this one is good enough for NFC

    One possible alternative would be to define the SPEAKER const in some sort of bootup file (or even just at the top of the source file to be uploaded) and let it be equal to D14

    I think you can just define it and it will work but I'm not sure (will need to read the sources that expand the json into def configuration). I might be able to get some time to experiment with this later this week (but not with the amiibo since it's a bit difficult to flash that one, the xiao ble has a usb bootloader that makes flashing. abit easier since I can just drag the hex file into the pseudo-filesystem).

    Sure, here you go.

    There's this grey thick sticker (maybe insulation rf shield?) behind the battery which could be where the nfc antenna are?).

    Not sure about the LEDs; I've looped through all the 32 pins and they are the only ones that light up. It's possible it's RGB but the LED module itself (near the top of the first picture) has four traces; two beside each other (which are likely the D17 and D20 pins) one going to a via and one going to what are probably resistors.

    What I did find work well is this one: http://www.radioland-china.com/1730323-1­730323_2575611.html

    Bought a few of these on AliExpress a couple of years ago (before the chip shortage): https://www.aliexpress.com/item/32965114­958.html

    Someone wrote custom firmware for this beacon (not Espruino): https://github.com/an-erd/ble_beacon

    Here you go :)

    The antenna performance seems to be quite bad while inside the plastic case though :( I was only able to connect to it every few tries and will often get disconnected, while having it outside of the plastic caseis more reliable.

    Found some interesting links while looking for amiibo related stuff :P

    I just got myself one of these. Cute litlle things :P

    I've initially flashed the nrf52832DK image and have been trying to get the pin assignments.

    It's been only a few minutes and I've only so far found that D17 is the green LED, and D20 is the red LED. The button is at D13. and the buzzer is at D14

    For board definitions I think just pasting them in the forum is fine (at least that's what I do, and where I look for others' board defs as well).
