I just ordered some Particle Mesh boards. First "mass production" boards with NRF52840. Would be very nice to get Espruino ported on those.
There is a referral program, my referral link is https://particle.io/mesh?referral=YKAM5S. I will donate everything - i.e. bonus boards - I get to @Gordon. Perhaps he could help on porting ;-).
IMHO it would be nice to get these boards for a few dollars more directly from @Gordon with Espruino installed (There was a discussion about this in the Patreon section of this board). They comply to the Adafruit Feather specs.
There's a little error in BH1745.js var MEASUREMENT_TIMES = [ 160,320,640,1280,1560,5120 ]. 1560 should be 2560 i think.
Xungtong perhaps. 1.27mm castellated. Normal and PA (amplified) versions, pin compatible. 1K pcs USD 4 normal and USD 5 PA.
For me, the MDBT42 module alone is too difficult to handle. I would like this or another module soldered on a small "baseboard" where the "baseboard" itself can be soldered onto "extension boards".
Best I found so far is https://www.tindie.com/products/ElectronutLabs/hackable-tiny-nrf52832-ble-development-board/ .
Imagine "extension boards" like 10DOF, Wifi, LoRaWAN etc.
My heart says Puck.js++ (circular pcb) but my brain says go rectangular. In that domain i would like to see something like Teensy 3.2. Lots of addons and shields, ie on Tindie.
I think you need to use " instead of ', see http://www.espruino.com/Modules
It's a library from 1v94 on. So probably you have an older version.
GSM and LTE are getting cheaper and cheaper: http://www.cnx-software.com/2017/07/26/hologram-lte-software-defined-global-network-for-cellular-iot-projects-starts-at-0-40-per-month-per-device/
I prefer a smaller footprint than arduino. Why not Teensy? Or Adafruit Feather? Or something else with a lot of addon boards.
... or probably not if you have been there already.
