M5Stack FIRE V2.7 adopts the Espressif ESP32 main control chip, equipped with two low-power Xtensa® 32-bit LX6 microprocessors, with a high frequency of 240MHz. It features an onboard 8M PSRAM + 16M FLASH memory combination and integrates a range of peripherals, including a 2.0-inch full-color high-definition IPS display panel, a 6-axis IMU, LED, microphone, speaker, and TFCard slot. With its powerful processing capability and stability, it is suitable for various product prototyping, industrial control, and intelligent building applications.

To ensure stable circuit operation, FIRE V2.7 employs a full-cover enclosure design, providing reliable circuit protection even in complex industrial application scenarios. FIRE V2.7 integrates abundant interface resources such as ADC, DAC, I2C, UART, and SPI interfaces, offering convenient avenues for user expansion needs. It is powered by a built-in lithium battery and also integrates a power management chip, supporting dual power supply options of Type-C interface and POGO pin interface. The base is equipped with a magnetic device and LEGO interface, allowing for flexible deployment and connection, enabling multiple usage scenarios.

Compared to the V2.6 version, M5Stack FIRE V2.7 has undergone an upgrade in terms of the screen, featuring a glass screen for a clearer display. Additionally, the glass screen has scratch-resistant characteristics, providing better screen protection and prolonging its lifespan.

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 and generating instability..

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 shutdown when USB power is on.

    High quality and versatile

    I haven’t had so much time to finish any project yet but the products are very promising.
    Many examples do not work so well.

    It’s okay

    I expected it to more capable. There’s not much firmware available that actually works well. Lots of crashes and freeze ups.
