UIFlow Arduino


M5Stack FIRE It‘ a cost-effective WiFi & Bluetooth dual-mode IoT controller adopts Espressif ESP32 main control chip, equipped with two low-power Xtensa® 32-bit LX6 microprocessors, with main frequency up to 240MHz. With 8M PSRAM + 16M FLASH memory, 2.0-inch full-color HD IPS display panel, IMU, LED, microphone, speaker, TFCard slot and other peripherals. The full-coverage case ensures circuit stability even in complex industrial applications. The internal offers a wide range of common interface resources (ADC/DAC/I2C/UART/SPI, etc.) which is highly expandable. This functional and powerful IoT controller is very applicable to various product prototyping, industrial control and smart building applications.

  • High productization.
    • Exquisite designs, Prototyping right into products
    • Product-grade full-coverage cover for more stable circuit operation
  • Low code development:
    • Support UIFlow graphical programming platform, scripting-free, cloud push
    • Fully compatible with Arduino, ESP32-IDF and other mainstream development platforms
    • Support FreeRTOS, with dual-core and multitasking mechanism, it can perform the tasks efficiently, Program optimization.
  • High integration.
    • 2.0-inch IPS display panel, 6-axis IMU, programmable RGB lights x10, microphone, speaker, custom buttons x3
    • Built-in Li-ion power, integrated power management chip, supports TypeC and POGO PIN
    • finely tuned RF circuit for stable and reliable wireless communication
  • Strong expandability.
    • GROVE expansion ports x3 (I2C, GPIO, UART)
    • Easy access to M5Stack software and hardware system, stackable module design, plug-and-play sensor expansion

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.

USB drive

Before using, please go to download page to download the USB driver that matches your operating system, and install it.
Note: FIRE currently has two CP2104/CH9102F A USB chip version, users can install the drivers (CH34x and CP210x) that are compatible with two ICs at the same time to ensure that the device drivers work normally.
