M5Stack GRAY Kit is one of the M5Stack development kit series, which is an upgrade from the Basic kits. In comparison, the Gray kit provides an extra IMU sensor, BMM150 + MPU6886. Gray kit is a nice choice for users who just get started or in progress.
With an IMU posture sensor, there are a lot of situations in which u can apply this kit to detecting acceleration, angulation, and trajectory. You can make relative products like sports data collectors, 3D remote gesture controller,s and more base on the above functions.
GRAY is an M5 Core device. Its modular, stackable, scalable, and portable device is powered with an ESP-32 core, which makes it open-source, low cost, full-function, and easy for developers to handle new product development on all stages include circuit design, PCB design, software, mold design, and production.
If you want to explore the fastest way of IoT prototyping, the M5Stack development board is the perfect solution. Not like others, the M5Stack development board is highly efficient, covered with industrial-grade case and ESP32-based development board. It integrates with Wi-Fi & Bluetooth modules and contains a dual-core and 16MB 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.
Supportive development platforms and programming languages: Arduino, Blockly language with UIFlow, Micropython. Regardless of what level of programming skill you have, M5Stack would guide you every step of the way to realize your idea as well as to the final productization.
If you ever played with ESP8266, you would realize that ESP32 is a perfect upgrade out of ESP8266. In comparison, ESP32 has more GPIOs, more analog inputs, and two analog outputs, multiple extra peripherals( like a spare UART ). Official developing platform ESP-IDF has transplanted with FreeRTOS. With dual-core and real-time OS, you can get more organized code and much high-speed processor.
