Feather of the Day: Adafruit Feather RP2040 with DVI Output Port #RP2040 #Adafruit #Feather
The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather RP2040 with DVI Output Port – Works with HDMI!
Wouldn’t it be cool if you could display images and graphics from a microcontroller directly to an HDMI monitor or television? We think so! So we designed this RP2040 Feather that has a digital video output (a.k.a DVI) that will work with any HDMI monitor or display. Note it doesn’t do audio, just graphics!
It’s kinda like we took our RP2040 Feather and DVI Breakout board and glued them together. You get all the pins for use on the Feather, the Lipoly battery support, USB C power / data, onboard NeoPixel, 8MB of FLASH for storing code and files, and then with the 8 unused pins, a DVI output that can be used CircuitPython or with the PicoDVI library in Arduino or Pico SDK
Note that the DVI video generation uses one full core, both PIOs, and 150K (320×240) or 190K (400×240) of SRAM. It’s kinda maxed out so be aware of the remaining resource limitations.
We also connected the HDMI-connectors I2C pins to the SDA/SCL of the Feather (through a safe level shifter) so you can read the EDID EEPROM of displays, and have broken out the CEC and Utility pads. The Hot Plug Detect pin is also available on the very end of the 16-pin header. Read this pin to know when a display has been connected!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
