Gray

SKU:K002

Description

Gray is an advanced development kit in the M5Stack series. As an upgraded version of the Basic kit, it offers larger Flash memory and integrates the IMU sensor MPU6886+BMM150. Whether for beginners or advanced users, the Gray kit is an excellent choice.

The IMU attitude sensor can be used in many applications to detect data such as acceleration, angle, and trajectory extension. Based on this, you can create related products such as motion data collectors and 3D remote gesture controllers.

With rapid prototyping and a very low threshold, the M5Stack development board is your best choice for IoT development. Traditional development boards can only be used for verification and learning, but the M5Stack board offers more possibilities. It features an industrial-grade case and exquisite design, providing stable performance. Besides verification and learning, it can also accelerate development and productization. It uses the ESP32 IoT chip, integrates a Wi-Fi module, has 4MB of SPI flash, and its dual-core low-power design performs exceptionally in various applications. The hardware expansion system, consisting of over 30 stackable M5Stack modules and over 40 expandable units, can quickly help you build and verify your IoT products.

Tutorial

Supported development platforms and programming languages: Arduino, UIFlow Blockly language, Micropython. No matter your development and programming skill level, M5Stack will assist you in gradually turning your ideas into reality.

If you have developed with ESP8266, you will find that ESP32 is a perfect upgrade. Compared to ESP8266, ESP32 has more GPIOs, more analog inputs, two analog outputs, and multiple peripheral interfaces (such as spare UART). The official development platform ESP-IDF has ported FreeRTOS, which, with dual-core and real-time operating system, allows you to organize your program code more efficiently and optimize program execution efficiency.
