    This micro:bit-based expansion board, specially designed for STEAM education, allows students to measure environmental conditions for scientific experiments by using rich on-board sensors that cover all basic aspects of nature and science in daily life, which helps them explore the related science knowledge and understand nature phenomenon. It aims to provide a platform for students to learn science theory with practices and bring science education closer to daily life!

    Integrated sensors include UV sensor, temperature sensor, humidity sensor, air pressure sensor, sound sensor, light sensor, water temperature sensor, and a TDS (Total Dissolved Solids) water quality sensor, soil moisture sensor, TVOC, CO2 sensor, etc.

    Environment Science Expansion Board V2.0 for micro:bit

    Board Overview


    V2.0 Update

    • Comes with WiFi-IoT card, support IoT platforms such as IFTTT, ThingSpeak, EasyIoT

    • MicroUSB power supply port, battery holder is welded on the PCB, more convenient for classroom teaching
    • Onboard 4-way RGB lights
    • 1-way motor driver
    • More powerful chip and more IO ports
    • Greatly optimized OLED display program, more convenient and flexible to use
    • The color sensor is removed from the list

    Product Features

    • Highly-Integrated (14 function modules): atmospheric pressure, temperature, humidity, harmful gases(TVOC), carbon dioxide, ultraviolet rays, light, sound, water quality, water temperature, soil humidity, buzzer, RGB light, OLED display, and motor driver.
    • IoT Function: able to be accessible to famous IoT platforms such as IFTTT, ThingSpeak, and EasyIoT through the WIFI-IoT card.
    • The interesting shape of the tree makes the classroom teaching more vivid and fun.


    • Power Supply: MicroUSB (5V ) /Three 1.5V AAA Batteries (4.5V)
    (Note: Because the power consumption of WIFI-IoT card is relatively large, it may not work properly if the AAA battery is low. Please use MicroUSB port to supply power to ensure the normal operation of the product when using it for class teaching.)
