Does anyone know how I could define a SPEAKER in the board config? As it is now I just use D14 directly, but it would be nice for compatibility if there was just a way to define it as SPEAKER. It seems like espruino should support it, but it doesn’t seem to for me

The antenna is under the battery, the “sticker” is a shield, and yes, you have to place the device button side down for it to read on some scanners like the Nintendo Switch.
The intended purpose of the AmiiboLink branded ones is to emulate amiibo dumps, so they definitely have NFC connected, and it works with espruino just fine… I’m not sure about NFC on the round BLE beacon PCB.

Here's the board definition I've made. LED1, and LED2 are functional as red/green. Speaker is in the definition, but it doesn't show up in espruino for some reason... I just use D14 directly.
There are multiple boards all being sold under the AmiiboLink name, but they include different firmwares and have different physical layouts. Pin assignments so far appear to be the same.

If it’s not enabled by default, I think it should definitely be behind an ifdef, or maybe enabled some other way. Maybe a DFU update that flips a byte flag somewhere?
It’s hard though, because you’re trying to secure functionality through a repl console that should ultimately be password protected by the user… I get what you’re saying though

I’m looking for a way to reboot into DFU mode without having to hold the button.
Is this possible? I’ve tried poking various 32-bit values into the address that should be GPREGRET, but it immediately reboots with all three LEDs on, and then back into espruino.
0x4000051c is the address I’ve been using, but I’m not so sure that’s correct.

I have a device called the “Amiibo Link”, it’s a board that can be found for around $8 or less on AliExpress.
Inside is an NRF52832 512/64KB, red / green LEDs, speaker, button, and an NFC antenna.
I have a board definition, but I’m not sure of the process involved, or if you’d even want to add it.
SWD pins are accessible through an unsoldered header, or even with oscilloscope clips if you’re careful to not scratch the solder mask on the ground plane.
Although I’m not quite sure how to assign a device like the speaker in the definition. To use it, 50% PWM at various frequencies changes the tone, and high or low on the pin seems to disable it altogether. Different PWM values do also change the tone and volume slightly.
A green residue keeps appearing on the rf shield over time on my puck.js, has anyone else had this happen? What is it?
It cleans off easily with isopropyl alcohol
