The shop says it doesn't include it, but isn't it part of the NRF52832 soc?

I also noticed that the board script for the firmware includes the NFC module.

Yes but typically you also need antenna and some tuning capacitors for it to work so that might have been removed to save cost.

For more details see https://infocenter.nordicsemi.com/pdf/nwp_026.pdf however it is said that few rings of thin copper wire without any capacitors might be sometimes good enough too. Which reminds me that I must finally try it.

by the way @Gordon, is the Puck.js online doc not rendering correctly? On my browsers (Firefox and Chrome) the pinout does not appear anymore

I'm afraid there isn't any NFC on Puck.js Lite. Good point about the NFC lib, I'll take it out the build.

Puck.js Lite is made with a 2 layer board, and it's not really possible to include the NFC aerial and the Bluetooth one (you want the NFC aerial on both layers really, and then you don't want the Bluetooth aerial inside the NFC aerial). It worked on the first Puck because Bluetooth was on a module (so there were effectively extra layers of PCB) but I couldn't manage it on the Puck Lite.

@Jean-Philippe_Rey wow, thanks! I see that too - I'll get that fixed now

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
