M5StickC PLUS2 is an iterative version of M5StickC PLUS, using ESP32-PICO-V3-02 chip as the main controller and built-in WiFi function. This compact device integrates rich functions in its small form factor, including infrared, microphone, LED, IMU, button, buzzer, etc. It has a 1.14-inch TFT screen with a resolution of 135 x 240 and is driven by ST7789V2. The battery capacity is increased to 200mAh, and the interface also supports HAT and Unit series products. This compact and versatile development tool is designed to inspire unlimited possibilities. M5StickC PLUS2 helps to quickly prototype IoT products and simplify the entire development process. Even programming beginners can easily build interesting applications with M5StickC PLUS2 and apply them to real-world scenarios. Power on: Press and hold "BUTTON C" for more than 2 seconds to start the wake-up, or trigger the signal at a time. After the wake-up signal is triggered, the hold (G4) pin needs to be set to a high level (1) during program initialization to maintain power supply, otherwise the device will enter the shutdown state again. Shutdown: Without USB external power supply, press and hold "BUTTON C" for more than 6 seconds; or without USB external power supply, set HOLD (GPIO4) = 0 during program operation to achieve shutdown.
