Description

The M5GO IoT Starter Kit v2.7 is a cost effective IoT starter development kit. The kit contains Core Controller M5GO + 6 expansion units with different functions (sensors/actuators/splitters). The core controller M5GO adopts Espressif ESP32 chip, equipped with 2 low-power Xtensa® 32-bit LX6 microprocessors, with a main frequency of 240MHz. With 16M FLASH memory for larger program size. Besides its powerful , the MCU also supports Wi-Fi, which can be used to build smart wearable devices, smart home and other applications.

Driver Installation

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.
