Doing a small production run

I've designed a PCB that uses the MDBT42Q module and want to do a small production run of 10 boards. I wanted to support Gordon by buying the MDBT42Q modules directly from the Espruino shop, but it seems that there's only 1 available?

I see I can also buy them from Verical, but how would I flash the Espruino firmware myself? Would I need to use SWD pins on my PCB, or is there a programming jig like with the Puck.js?

Sorry for the delay getting back to you - we'll actually have programmed MDBT42Q modules back in stock by the end of today.

But to flash them yourself, you'd ideally need to use SWD pins on your PCB, yes. I believe Raytac may sell an (expensive) flashing jig, or you could make your own though.

Thanks Gordon! I'll put SWD pins on my PCB, but will be ordering the modules from you in the near future.

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:
![](https://www.google.co.uk/images/srpr/logo4w.png)
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.
