HDMI to screw terminal adapters could be useful for Raspberry Pi RP2040 and RP2350 boards

The very idea of an HDMI to screw terminal adapters maybe seem moronic at first, but in an era of programmable IOs (PIO), and high-speed serial transmit (HSTX), those could end up being useful for boards or modules based on Raspberry Pi RP2040 or RP2350 since they’ve all be shown to support DVI output through HDMI connectors.

There are a few boards that integrate an HDMI port such as the Olimex RP2040-PICO-PC, Solder Party RP2xxx Stamp Carrier XL, or Adafruit Feather RP2040 among others, but most boards don’t include an HDMI port. What they do typically have are GPIO headers, and an HDMI to screw terminal adapter would allow users to easily add an HDMI port to their existing board without soldering simply by using jumper wires, or with a bit more work an old HDMI cable.

All HDMI to screw terminal adapters are pretty basic with an HDMI male connector compatible with HDMI 2.0 (24AWG) and two terminal blocks with 10 poles each all housed in a plastic enclosure. No soldering is required unless your module/board does not come with headers with only through or castellated holes.

While there are 20 pins in total wiring to a Raspberry Pi RP2040 should only require about 11 pins based on the schematics for the PicoDVI project.

HDMI to screw terminal adapters are fairly inexpensive going for $8.99 on Amazon with a screwdriver, but you can bring that down to under $6 per pieces by purchasing bundles with five pieces. AliExpress even has cheaper models for about $5 with screw terminals or even $3 if you’re open to doing some soldering.
