Grove WiFi 8266 module is designed to enable your micro:bit (and other controllers too) to send/receive data over the internet through the Wi-Fi network. It is based on the Ai-Thinker's ESP-12F module and comes preloaded with the new Espressif ESP-AT firmware v2.2.0. 

MakeCode extension is provided to help you go straight to building your awesome IoT projects with this super intuitive drag-and-drop programming interface. With this MakeCode extension, REKA:BIT can work seamlessly with the Grove WiFi 8266 module, thanks to its external power input feature that ensures sufficient power for the WiFi module to run properly.


Besides, we've also created the CircuitPython libraries for Raspberry Pi Pico and RP2040 devices. You can plug in the Grove WiFi 8266 module directly onto the Maker Pi RP2040 via any of the Grove ports, thus enabling it for IoT applications.


By utilizing the MakeCode extension & CircuitPython libraries, you can monitor your sensor data on ThingSpeak easily. ThingSpeak is available as a free service for non-commercial small projects. You can send up to 3 million messages a year or about 8,200 messages a day, with a 15 seconds message update interval limit.


Grove WiFi 8266 enables your non-IoT enabled controller boards to get connected to the internet. With Blynk, a user-friendly IoT platform, you are able to control the connected projects and read data from the sensors easily.


Telegram API is also supported by our MakeCode extension & CircuitPython libraries. You can deploy a secret compartment keeper to guard your precious chips and notify you via Telegram whenever the drawer is opened or closed. 


All the pins of the ESP-12F are extended out to the standard 2.54mm (0.1 inch) pitch-to-pitch through-hole pads, should you need to access them.


  • Based on ESP-12F (ESP8266 MCU) WiFi module

Q & A (5)
How can I get the Grove WiFi 8266 - IoT for micro:bit and beyond to work with IFTTT on a Micro:bit? Extension update please. ( Jeff, 08/09/2022 )
Hi, Theoretically yes, need to update the extension to support IFTTT. But we haven't looked into IFTTT for quite some time and don't have the resources to do it any time soon. You may use arduino for the to support IFTTT.
hello, is it possible to change the firmware of the Grove WiFi 8266 with arduino ?thanks ( karl, 29/08/2022 )
We suggest you to use this ESP01 USB Programmer Adapter to update the firmware and you may follow guide written here : How to update ESP-AT firmware. More information about firmware here :Cytron custom compiled ESP-AT firmware
Is the extension able to work with the new Blynk 2.0? ( Tay Boon Leong, 24/02/2022 )
Hi. Please send an email to
Is this board compatible with Arduino? Thank You. ( Nilanjan Mandal, 30/01/2022 )
Yes, you can use it with an Arduino board, for example Arduino UNO.
May i know is it compatible with Edu-Bit or motor bit? Thank you. ( Aloysius Tan , 26/09/2021 )
Yes, it's compatible with EDU:BIT and any micro:bit expansion board as long as it breaks out the micro:bit IO pins. If the board doesn't come with the Grove port, you may need this cable for connection
