I am selling this because I couldn't use it. The M5GO IoT Kit v2.6 is a high-cost-performance introductory IoT development kit. The kit includes the core controller M5GO and six expansion units (sensors / actuators / hubs) with different functions. The core MCU M5GO is equipped with Espressif's ESP32 chip and features two low-power Xtensa® 32-bit LX6 processors (up to 240MHz clock). With the onboard 16MB Flash large-capacity storage, larger programs can be stored. In addition to its powerful hardware performance, this MCU also supports Wi-Fi, enabling the development of applications such as wearable devices and smart homes.
