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.

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 corresponding to 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 it.) If you encounter issues with downloading programs (timeout or Failed to write to target RAM), try reinstalling the device drivers.
