Fire v2.6

SKU:K007-V26

Description

Fire v2.6 is a cost-effective Wi-Fi IoT controller. It uses the Espressif ESP32 main control chip, equipped with 2 low-power Xtensa® 32-bit LX6 microprocessors, with a main frequency of up to 240 MHz. The board comes with 8M PSRAM + 16M FLASH memory combination, integrated 2.0-inch full-color HD IPS display panel, IMU, LED, microphone, speaker, TFCard slot, and other peripherals. The fully covered shell ensures stability of circuit operation even in complex industrial application scenarios. The internal bus provides a variety of common interface resources (ADC/DAC/I2C/UART/SPI, etc.), with strong expandability. This feature-rich, high-performance IoT controller is very suitable for various product prototype development, industrial control, and smart building application scenarios.

Power On/Off

Power On/Off Operation

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, when powered by USB, it cannot be turned off

Note:
GPIO 16 / 17 in FIRE are by default connected to PSRAM, so when connecting or stacking other functional modules, be careful to avoid conflicts with these two pins to prevent the device from malfunctioning and causing instability.

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)/CP34X (for CH9102 version) driver packages. After extracting the 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, just ignore it.) If you encounter issues with downloading programs (timeout or Failed to write to target RAM), try reinstalling the device drivers.
