Fire

SKU:K007

Description

Fire is a high-performance development kit in the M5Stack series. As an upgraded version of the Gray kit, it features a nine-axis motion sensor (six-axis accelerometer + three-axis magnetometer) and enhanced hardware resources: 16MB Flash, 8MB PSRAM, an enhanced Base (M5GO base and M5GO charging base), and a larger capacity battery. For developers with demanding hardware performance requirements, Fire is an excellent choice.

The motion sensor can be used in various applications to detect acceleration, angle, trajectory extension, and other data. Based on these, related products such as motion data collectors and 3D remote gesture controllers can be developed.

Fire consists of three detachable parts. The top part, like other M5 hosts, contains the circuit board, chips, LCD screen, 2.4G antenna, various electronic components, and interface components. The middle part is called the M5GO base, which provides a lithium battery, M-BUS bus socket, LED strip, and three GROVE expansion ports. The bottom part is the charging base, which can be connected to the M5GO base via POGO pins for charging.

Tutorial

Supported development platforms and programming languages: Arduino, UIFlow Blockly language, and MicroPython. Regardless of 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 offers more GPIOs, more analog inputs, two analog outputs, and multiple peripheral interfaces (such as additional UARTs). The official development platform ESP-IDF has already ported FreeRTOS. With dual-core and real-time operating system support, you can organize your code more efficiently and optimize program execution.

Power On/Off

Power On/Off Operations

Power On: Click the red power button on the left
Power Off: Quickly double-click the red power button on the left
USB Power Supply: By default, the device cannot be powered off when connected to USB.

Note:
GPIO 16 / 17 in FIRE are connected to PSRAM by default. Therefore, when connecting or stacking other functional modules, be careful to avoid conflicts with these two pins to prevent unstable operation.

USB Driver

Click the links below to download the drivers for your operating system. There are currently two versions of driver chips: CP210X (for CP2104 version) and CP34X (for CH9102 version). After extracting the compressed package, select the installation package corresponding to your operating system's bit version. (If you are unsure which USB chip your device uses, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but it is actually installed successfully, so you can ignore it.) If you encounter issues with downloading programs (such as timeouts or "Failed to write to target RAM"), try reinstalling the device drivers.
