The FIRE V2.7 uses the Espressif ESP32 main control chip, which includes two low-power Xtensa® 32-bit LX6 microprocessors operating at a high frequency of 240MHz. It comes with 8M PSRAM and 16M Flash memory and integrates various peripherals such as a 2.0" full-colour HD IPS display panel, a 6-axis IMU, LED, microphone, speaker, and SD card slot. Its powerful processing capabilities and stability make it ideal for product prototyping, industrial control, and intelligent building projects. It has a full-cover case design that provides reliable circuit protection in tough working areas. It also includes a variety of connectivity resources like ADC, DAC, I2C, UART, and SPI connectors, providing great options for expansions. It is powered by a built-in lithium battery and also includes a power management chip, supporting dual power supply options via USB-C connection and POGO pin connection. The base includes a magnetic device and LEGO connection, allowing for flexible deployment and connection in multiple scenarios. Compared to the V2.6 version, the M5Stack FIRE V2.7 has an improved screen with a glass surface for a clearer display. The glass screen is also scratch-resistant, offering better protection and extending its lifespan. Note: GPIO 16 / 17 of FIRE are connected to PSRAM by default, so when you connect or stack other modules, you need to pay attention to avoid conflicts with these two pins to prevent the device from not working properly. Switching Operations * Power on: Click the red button on the left * Power off: Quickly double-click the red button on the left * USB power: By default, It can not be shut down when USB power is on.

There are currently two driver chip versions, CH9102 driver compressed package. After decompressing the compressed package, select the installation package corresponding to the number of operating systems to install. (If you are not sure of the USB chip used by your device, you can install both drivers at the same time. During the installation process of CH9102VCPSERMacOS v1.7, an error may occur, but the installation is completed, just ignore it.) When using it, if the program cannot be downloaded normally (the prompt is over time or failed to write to target RAM), you can try to reinstall the device driver.
