Overview
The M5StickC PLUS2 is an ultra-compact ESP32 IoT development kit from M5Stack, featuring the ESP32-PICO-V3-02 system-in-package with 2MB PSRAM and 8MB Flash. Packed into a 48×24×13.5mm stick form factor weighing only 16.7g, it integrates a 1.14-inch color TFT display, MPU6886 6-axis IMU, RTC, MEMS microphone, IR emitter, buzzer, and a 200mAh lithium battery. It supports Wi-Fi and Bluetooth connectivity, and is programmable via Arduino IDE, MicroPython, and UIFlow. The HY2.0-4P expansion port provides access to I2C, I/O, and UART for connecting M5Stack's extensive HAT and Unit ecosystem. Note: This product is End of Life (EOL) and replaced by the M5StickS3 ESP32-S3 variant.
