M5GO IoT Kit

SKU:K006

Description

The M5GO IoT Kit is a development kit from the M5Stack series designed for STEM education. In addition to the main M5GO unit, the kit includes 6 different functional Units and some LEGO bricks and other accessories. M5GO not only has rich hardware resources but also comes with a wealth of educational videos, textbooks, technical documents, and other materials. It plays an important role in STEM education for students of all ages.

The kit provides an online version of the WebIDE UIFlow programming platform, allowing students to experience the power of IoT through network-based program deployment. It also supports multiple programming methods, helping students gradually transition from graphical programming to understanding actual code.

As a kit specifically designed for STEM education, M5GO aims to make learning fun while helping students gain a sense of accomplishment by turning their creative ideas into reality. It allows students to freely explore the world of engineering, create their own IoT products, and integrate their brilliant ideas into real life.

BMM150 Magnetic Field Interference

Products with magnets may interfere with the BMM150 magnetic field sensor, causing abnormal readings. When used with an M5 master control device containing a magnet, the magnet needs to be removed, and at the same time, the BMM150 sensor should be kept away from strong magnetic fields.

Power On/Off

Power On/Off Operations

Power On: Click the red power button on the left
Power Off: Quickly double-click the red power button on the left

USB Driver

Click the links below to download the drivers for your operating system. There are currently two versions of driver chips: CP210X (for CP2104 version) / CP34X (for CH9102 version) driver packages. After extracting the package, select the installation package that matches your operating system's bit version. (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 it is actually installed successfully, so you can ignore the error.)
