Boardoza FT800 TFT Driver Breakout Board

The Boardoza FT800 TFT Driver Breakout Board is a powerful graphics controller solution designed to simplify the creation of high-quality Human-Machine Interfaces (HMIs) for makers and embedded developers. Powered by the Bridgetek (FTDI) FT800 Embedded Video Engine (EVE), this module unburdens your main microcontroller by handling complex graphics rendering, audio processing, and touch control on a dedicated chip. It is the perfect bridge for connecting low-cost MCUs to sophisticated color displays.

Operating with a 5V supply, the board communicates via a standard SPI interface at speeds up to 30 MHz, making it compatible with popular platforms including Arduino, ESP32, STM32, and Raspberry Pi. It supports WQVGA (480x272) and QVGA (320x240) resolution TFT displays through a standard 40-pin FPC connector. Beyond graphics, it includes a built-in audio engine with PWM output for direct speaker connection. The FT800 offers flexible touch input options with integrated resistive touch support and native capacitive touch connectivity via I²C, providing a complete multimedia solution for industrial control panels, medical devices, IoT projects, and smart home interfaces.
