The M5StickC PLUS is a compact, portable, and open-source IoT development board powered by the ESP32-PICO-D4 with built-in Wi-Fi. It’s an enhanced version of the original M5StickC, featuring a larger display and improved hardware design. The upgraded 1.14-inch TFT LCD screen (135×240 resolution) increases the display area by 18.7%. It also includes a buzzer and a higher-capacity 120mAh LiPo battery (up from 95mAh), making it ideal for wearable and embedded applications. The device integrates rich hardware resources: infrared transmitter, RTC, microphone, LED, IMU, buttons, and PMU. It supports the HAT and Unit series from M5Stack and is compatible with multiple development platforms. Power switch operation: Power on: Press power button for 2 seconds Power off: Press power button for 6 seconds Product Features ESP32-PICO-D4 with Wi-Fi Built-in 6-axis IMU (MPU6886) Red LED indicator Infrared transmitter Digital MEMS microphone (SPM1423) Real-time clock (BM8563) Custom buttons + 1.14-inch LCD 120mAh rechargeable LiPo battery Extendable socket for HAT/Unit modules Built-in passive buzzer Wearable or wall-mounted design Multi-platform development support: UIFlow MicroPython Arduino .NET nanoFramework Package Includes 1 × M5StickC PLUS with watch accessories Applications IoT terminal controller Wearable devices STEM education tools DIY electronics and prototyping Specifications Resources Parameter ESP32 240MHz dual-core, 600 DMIPS, 520KB SRAM, Wi-Fi Flash Memory 4MB Power Input 5V @ 500mA Ports Type-C × 1, GROVE (I2C + I/O + UART) × 1 LCD Screen 1.14-inch, 135×240 Color TFT LCD, ST7789v2 Buttons Custom buttons × 2 LED Red LED IMU MPU6886 Buzzer Built-in passive buzzer IR Infrared transmission Microphone SPM1423 RTC BM8563 PMU AXP192 Battery 120mAh @ 3.7V Antenna 2.4G 3D antenna PIN Ports G0, G25/G36, G26, G32, G33 Operating Temperature 0°C to 60°C Net Weight 15g Gross Weight 21g Product Size 48.2 × 25.5 × 13.7 mm Package Size 50 × 25 × 15 mm Case Material Plastic (PC) Schematics StickC-Plus Schematic PDF Datasheets ESP32-PICO ST7789v2 BM8563 MPU6886 AXP192 Datasheet AXP192 Register SPM1423 Microphone Software Support Arduino StickC-Plus Arduino Library
