Outputting digital video is nothing new for the Raspberry Pi Pico. Again within the early days, Raspberry Pi engineer Luke Wren devised the Pico DVI Sock, grafting HDMI onto the Pico. That challenge was later refined into PicoDVI. Adafruit’s newest board, Feather RP2040 with DVI could not have a catchy title, but it surely integrates HDMI / DVI output into its acquainted Feather kind issue.

The RP2040 SoC has graced Adafruit’s Feather kind issue earlier than. The Adafruit Feather RP2040 obtained the Editor’s Alternative award upon its launch and has stayed in our Finest RP2040 Boards for 2 years.
The shape issue could not give us all of the GPIO pins of the Pico, however we get Stemma QT, onboard battery charging and easy-to-read GPIO pin references. The Feather RP2040 with DVI offers these actual options and likewise offers a digital video output, DVI, that can work with any HDMI monitor if in case you have an HDMI-to-DVI adapter. For now, although, there isn’t any sound

|Row 9 – Cell 0||Scorching swappable Li-Po charging port|
|Video Output||640 x 480 or 800 x 480|
|Dimensions||53 x 23.3 x 7.7mm|
Adafruit boards are intrinsically linked to CircuitPython, however to get essentially the most from this new board you will want to make use of the PicoDVI library for Arduino or the Pico SDK. Producing video through the RP2040 requires one core of the twin core SoC and makes use of each Programmable IO (PIO).
Assets will likely be tight as producing a 320 x 240 video will take 150KB, and 400 x 240, 190KB of the 264KB SRAM. The HDMI connector has its I2C pins related to the SDA / SCL pins of the Adafruit Feather RP2040 with DVI. This permits customers to learn the EDID EEPROM of a show, useful for debug.
Adafruit has listed the Adafruit Feather RP2040 with DVI as “coming quickly” and for now there isn’t any worth listed.
