Fire v2.7
SKU:K007-V27
Description
Fire v2.7 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. It has an onboard memory combination of 8M PSRAM + 16M FLASH, integrating a 2.0-inch full-color high-definition IPS display panel, IMU, LED, microphone, speaker, TFCard slot, and other peripherals. The fully covered casing ensures the stability of circuit operation even in complex industrial application scenarios. The internal bus provides a variety of commonly used interface resources (ADC/DAC/I2C/UART/SPI, etc.), making it highly expandable. This feature-rich, high-performance IoT controller is very suitable for various product prototype development, industrial control, and smart building application scenarios.

USB Driver
Click the link below to download the driver for your operating system. There are currently two driver chip versions, CP210X (for CP2104 version) / CP34X (for CH9102 version) driver package. After extracting the package, select the installation package corresponding to your operating system bit for installation. (If you are unsure of the USB chip used by your device, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but it has actually been installed, just ignore it.) If you encounter issues downloading programs (timeout or Failed to write to target RAM), try reinstalling the device driver.
