Overview
Hex display is an open-source printed circuit board by bitaxeorg, from the bitaxeorg/ultraHex repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 2-layer board of 47 × 29 mm with 6 parts on 9 nets, routed with 37 tracks and 11 vias.
Its parts include 1 IC and 1 connector. It belongs with the lEDs and displays boards of this library.
README
hex-display/readme.mdBitaxeHex display adapter board
This adapater board provides a connection from the BitaxeHex to a 172x320 SPI interface ST7789 Drive OLED graphic display. This is intended for use on the bitaxeHex. Currently, the firmware to drive it has not been developed, so this is provided in order to facilitate that effort.
The cable to connect it is constructed with a pair of JST-GH 12-pin housings, and cables that run straight through.
Parts
To construct the cable:
- qty 12 of the pre-crimped cables
- qty 2 of the JST-GH housings
Insert the cables into the housings with the locking pin facing the same direction (both towards you)

Questions
How big is the Hex display PCB?
It measures 47 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hex display use?
6 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hex display KiCad files?
From the bitaxeorg/ultraHex repository on GitHub, at the commit this page was made from: the board is hex-display/hex-display.kicad_pcb and its schematic bitaxeHex.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hex display design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
