Adafruit FPC Breakout for Raspberry Pi 5 DSI or RP2350 HSTX – 22 Pin 0.5mm

This little breakout board is specifically designed for use with Raspberry Pi 5 or our RP2350 boards that have an ‘HSTX’ connector. These devices use a semi-standard FPC connector to pipe high-speed data for video transmission over differential pairs. But maybe you want to make a custom setup or adapt to a different product? This doohickey is your pal.

You can use a 22-pin 0.5mm pitch FPC cable to connect between the two boards to access the four (Pi 5) or three (HSTX) differential data channels, plus the differential clock. There’s also a 3.3V power output, I2C, and two GPIO. We placed a fairly big ground plane and we did our best to route the signals cleanly but any time you solder wires or use a bread/perf-board with a high-speed signal there’s a risk of signal degradation!

Each order comes with one breakout board, a 22-pin FPC cable is NOT included.
