    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.

    FEATURES

    V2.0 Update
