M5Stack CORE – GRAY Version



Description


M5Stack CORE – GARY Version is from one of the M5Stack development kit series, it’s a upgrade from the Basic kits. In comparison, Gray kit provide a extra IMU sensor, MPU9250.

With a IMU posture sensor, you can include posture detection in your work : accelerated speed, angulation, and trajectory detection. You can make relative products like sports data collector, 3D remote gesture controller and more.

Ever wanted to explore the fastest way of IoT prototyping, M5Stack development board is the perfect solution. Not like others, M5Stack development board is highly productlized, covered with industrial grade case, and ESP32-based development board. ESP32 is a hybid Wi-Fi & Bluetooth chip contains a dual-core and 4MB of SPI Flash . Together with 30+ M5Stack stackable modules, 40+ extendable units, and different levels of program language, you can create and verify your IoT product in a very short time. Supported development platforms and program languages: Arduino, Blockly language with UIFlowMicropython. Regardless of what level program skill you have, M5Stack would guide you in every step of the way to realize your idea as well as to the final productilization.

If you ever played with ESP8266, you would realize that ESP32 is a perfect upgrade from ESP8266. In comparison, ESP32 is full-feathered with more GPIO, plenty of analog inputs and two analog outputs, multiple extra perpherials( like a spare UART ). Official development platform ESP-IDF have planted with FreeRTOS. With dual-core and real time OS you can get more organized code and much high speed processor.

This is a Bottom board on the back of M5Core. It’s designed for expanding gpio on M-Bus besides I2S Pins(GPIO0, GPIO12, GPIO13, GPIO15, GPIO34)for DIY. Each gpio on M-Bus is expanded as pin and port for convenience and flexibility.
