These are standard ESP8266 ESP01 WiFi modules as shown on the Espruino ESP8266 page. Add WiFi to your Espruino with just 5 wires!
ESP01 can be connected directly to:
- Espruino Pico (shim available for low profile mounting)
- MDBT42 Breakout
- Multicolour Pixl.js
Other boards such as the Espruino Original and Pixl.js do not contain powerful enough 3.3v voltage regulators to reliably power the ESP01, so while it can be added you'll need a separate 3.3v voltage regulator. Puck.js does not contain a voltage regulator at all so could only be used with an external 3.3v supply.
These modules have 0.40 firmware - the AT+GMR command reports:
