M5GO IoT Kit

SKU:K006

Description

M5GO IoT Kit is a development kit in the M5Stack family that targets STEM education. In addition to the main controller M5GO, the kit includes 6 Units with different functions and various LEGO bricks and other accessories.
M5GO not only provides abundant hardware resources, but also offers a wealth of teaching videos, textbooks, technical documents, and more. It plays an important role in STEM education for students of all ages.
The kit comes with the cloud-based WebIDE UIFlow programming platform. By pushing code through the network, students can truly experience the power of the Internet of Things. Multiple programming options are supported, helping students gradually transition from block-based coding to understanding actual source code.
As a kit designed specifically for STEM education, M5GO aims to let students gain knowledge while having fun, and enjoy the sense of accomplishment that comes from turning creative ideas into reality. Students are free to explore the world of engineering, build their own IoT products, and integrate brilliant ideas into real life.

USB Driver

Click the links below to download the driver package that matches your operating system. Two driver chip versions exist: CP210X (for CP2104) and CP34X (for CH9102). After extracting the archive, choose the installer that matches your OS bitness.
(If you are unsure which USB chip your device uses, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but the driver is actually installed—just ignore the warning.)
