+1 for a STEMMA or Grove "standard" connector. That would be marvellous for IoTKG. I would think, STEMMA is preferable as it is also compatible with DF Robot Gravity. https://learn.adafruit.com/introducing-adafruit-stemma-qt/dfrobot-gravity
On a related note, can you already reveal anything about the new board, Gordon? From my perspective, the Puck is embedded perfection, it's just missing Wifi. A Wifi+BLE Puck would be just the thing!

Hello,
jumping in late ... it seems that this is no longer relevant for @Raik, but for what it's worth: I ordered expansion shields for ESP8266 from quite a few ebay sellers. Each and every order was cancelled by the respective seller after a few days. All for the same reason: "quality problems with the module". I now have quite a few ESP8266 lying around, but no adapter expansion shield :)
This is the type of module I'm talking about: https://www.ebay.com/itm/Duinopeak-ESP8266-ESP-01-WiFi-Expansion-Board-Shield-Without-ESP8266-Module-For/312730751293?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
I finally managed to obtain a different type of WiFi module here:
https://www.ebay.com/itm/ESP-12E-ESP8266-UART-WIFI-Wireless-Shield-for-Arduino-UNO-R3/254282142174?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649These have arrived, but i haven't managed to test them yet. Hopefully sometime during the end-of-year break.

That’s definitely one exciting device. I’m using Espruino in outreach projects that are focused on IoT sensor technology, and this would be the best matching device that exists in the market. Just a real shame they don’t have LoRaWAN on board :(( I’d love to see an Espruino equivalent of LoPy4 our FiPy with PySense (or maybe see Espruino ported to these :)

Great, I’ll order some and give them a go. Will post an update here once I’ve found out. Thanks again.

Hi Gordon,
thanks for your advice - quick as always... much appreciated!
Do you think that either / both of these would work? (They both claim to have voltage regulators).https://boggleup.com/products/duinopeak-esp8266-esp-01-wifi-expansion-board-shield-without-esp8266-module-for-arduino - needs the separate module, but that doesn't bother me.
If you think they should work, i'll just try both.
The Sparkfun board also seems to look good but it requires soldering the headers on and the reviews are pretty mixed (why don't they sell a version with headers???)

Thanks,

Hello,
has anyone found a wifi shield that works on the Pixl.js without any rewiring or modification? I am aware of this tutorial: http://www.espruino.com/arduino-esp8266, which is great... Unfortunately, my target group for this project (very young students) won't be able to change the boards. Hardware has to be plug and play, which is the primary reason for choosing Espruino in the first place.
The development goal is a BLE GATT to MQTT via Wifi gateway. Unfortunately, the Espruino Wifi won't work for this either, since it doesn't support BLE. Any pointers appreciated.
Best,

That’s good to hear. In that case it’s probably better to use the UART. Thanks!
using Espruino in outreach projects (schools and beyond). For example, see the Internet-of-Things Kitchen Gardens https://iotkg.org/
