M5GO IoT Kit v2.6 is a cost-effective IoT starter kit. The kit includes the M5GO core controller + 6 expansion units (sensors/actuators/splitters). The core controller M5GO is powered by the Espressif ESP32 chip, equipped with 2 low-power Xtensa® 32-bit LX6 microprocessors with a clock speed of up to 240MHz. It comes with 16MB FLASH memory, allowing for larger program sizes. In addition to its powerful hardware, this MCU also supports Wi-Fi, enabling the development of applications such as smart wearable devices and smart home solutions.

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.

Click the link below to download the driver that matches the operating system. There are currently two driver chip versions, CP210X (for CP2104 version)/CP34X (for CH9102 version) driver compressed package. After decompressing the compressed package, select the installation package corresponding to the number of operating systems to install. (If you are not sure of the USB chip used by your device, you can install both drivers at the same time. During the installation process of CH9102_VCP_SER_MacOS v1.7, an error may occur, but the installation is actually completed, just ignore it.) When using it, if If the program cannot be downloaded normally (the prompt is overtime or Failed to write to target RAM), you can try to reinstall the device driver.
