TFP401 HDMI/DVI Decoder to 40-Pin TTL Breakout - With Touch

Introducing the Mini HDMI Decoder Board – a compact, all-in-one display driver designed for TTL displays or decoding HDMI/DVI video for various projects. This breakout features the TFP401, a robust DVI/HDMI decoder, and the AR1100 USB resistive touch screen driver for the touch version.

The TFP401 can decode unencrypted video and output raw 24-bit color pixel data (HDCP not supported), handling resolutions up to 1080p and pixel clocks ranging from 25-165MHz. It’s compatible with basic TTL display panels, and we’ve successfully used it with 800x480 displays. While it hasn’t been tested with higher resolutions, it’s a versatile solution for small display projects.

Key Features:

• TFP401 Decoder: Supports unencrypted HDMI/DVI video, outputs raw 24-bit color pixel data
• Resolution Support: Decodes resolutions up to 1080p with pixel clocks from 25-165MHz
• Touch Version: Includes AR1100 USB touch screen driver for use with resistive touch displays (USB port provides both power and data)
• Backlight Control: Includes backlight driver and a PWM input for controlling backlight brightness via microcontroller
• USB Powered: Powers both display and decoder from a single USB port (500mA total for 5” 800x480 display with backlight at full brightness)
• Compatible with Linux: Works with Mac, Windows, and Debian Linux (Raspbian on Raspberry Pi); Linux distributions may vary in compatibility
• Ideal for Single Board Computers: Perfect for use with systems like Raspberry Pi or BeagleBone Black with DVI/HDMI output
• Display Compatibility: Works with our 4.3", 5", and 7" TTL displays (recommended for 5" and 7" 800x480 displays)
• Customizable EDID: Ships with an 800x480 EDID, reprogrammable via Arduino code or forced resolution in Linux

Please note: This is just the decoder breakout; a display is not included. We recommend pairing it with the 5” or 7” 800x480 display with touch for optimal performance. Check out our tutorial for adjusting backlight brightness and details on customizing the EDID for different resolutions. For more distance between the driver and display, consider our 40-pin FPC extension board.

Revision History:

• As of February 20, 2024 – We updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen, as well as with a plug-n-play Stemma QT connector for the EDID EEPROM, in case you want to reprogram it.

Specifications:

• Dimensions: 51mm x 68mm x 8.5mm
• Weight: 18.7g
