I'm an electrical engineer who spends to much time automating his house. I post about my projects on http://www.addictedtopi.com

    I definitely swapped the ch340g pins a few times to be sure. Not sure if I swapped the pins on the pl2303hx, but both pins had the same voltage on when measured. All good for me now that I found one that works, but could be a bit harder to work out for someone who doesn't have a pile of random usb-uart modules lying around.

    I flashed the espruino_1v97.99_nrf52832.hex travis build to an MDBT42Q module to give it a spin but couldn't connect via serial. I can connect to it via BLE but serial just wasn't working. I found the notes about it needing to see 3.3V on D8 so I checked it out and found that my CH340G (clone?) only had about 1.7V on RXD. I grabbed another USB-serial module, this time a PL2303HX (clone?) and found only about 0.6V on RXD. Finally tried a CP2102 (clone?) and it worked fine with 3.3V on RXD in idle.

    My reference devices are all off aliexpress and not necessarily reliable adherers to good UART practices, but detecting full voltage on that pin might not be a good indicator of when a serial connection is there. Maybe checking for >0.5V using the ADC would be more reliable? I imagine this would affect a puck-js as well, I can't test on mine because I've got the pins already soldered to something.

    Not a fan of the arduino footprint. It's a trade-off between being compatible with loads of shields and otherwise being quite useless with the irregular spacing and not breadboardable. My current favorite form-factor is the adafruit feather, but I think they've already got an nrf52 board...

    Sounds like a good way to handle the situation. Your work is appreciated @Gordon, it's amazing that Espruino is all done by one person.

    Having any sort of paid service at all might result in a sizeable revenue stream. I'm sure there are plenty of people on here that feel like they get a lot more value out of espruino boards and software than the cost of buying a board or two. Being able to sign up to a service that you don't 100% need, but is cool and makes you feel you're giving back can work.

    Maybe something like a basic/silver/whatever membership could give you a vote on newest features, early access, forum badge and all that. Then a gold/premium membership might get you priority support, automatic custom builds, fancier forum badge.

    I don't need a cool forum badge, but I'd sign up for one to support Espruino because it's awesome...

    Thanks for another year of awesome @Gordon, have a great holiday!

    @user70533 the espruino website has a lot of info for getting started. http://www.espruino.com/Modules shows how to use modules and http://www.espruino.com/Reference has details about everything built-in. On the whole, I've been able to easily port code between node and espruino and just replace the modules and their calls with equivalents, it didn't take long to get used to. Definitely a lot easier, more powerful and faster than making a jump to writing c for arduino, and having a command line to work with on your microcontroller is amazing!

    For reference, I think this the last time espruino with freertos was attempted:
