opensrxcard is an open source SRX card project that consists of
- An SRX card that can be used in Roland devices like the Fantom X/XR (other 5V devices like XV5080/XV3080 etc. in the future)
- An Arudino Due based programmer that allows to dump, program and erase SRX cards.
This is work in progress. Keep watching.

Questions
How big is the Srx card PCB?
It measures 73.7 × 36.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Srx card use?
21 parts, built around the TX24-80R-6ST-H1E. 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 Srx card KiCad files?
From the synthtools/opensrxcard repository on GitHub, at the commit this page was made from: the board is kicad/srx-card-3.3v/srx-card.kicad_pcb and its schematic kicad/srx-card-3.3v/srx-card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Srx card 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).
