Documentation | Source | Join us on Matrix!
Flashkeeper is a family of open-hardware add-ons for standard SOIC-8 and WSON-8 SPI NOR flash chips (as are commonly used for firmware storage in PCs and other electronics), providing functionality for write-protection control, SPI bus breakout, flash device emulation, reprogramming, and state validation.
Flashkeeper development takes place on the 15h.org Git forge, and is mirrored to Github as a backup. If you wish to participate in Flashkeeper development on 15h.org infrastructure, please request an account in either the Flashkeeper room or the 15h.org room on Matrix. Issues may be opened on either 15h.org or Github.
For user information, please see the documentation. For hardware source files, see hw/.
The Flashkeeper project is supported by NLnet NGI Zero Core.

Questions
How big is the Spyspy board PCB?
It measures 40.2 × 92.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spyspy board use?
12 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 Spyspy board KiCad files?
From the linuxboot/flashkeeper repository on GitHub, at the commit this page was made from: the board is hw/spispy_board/spyspy_board.kicad_pcb and its schematic hw/adapter_soldered/breakout_wide/adapter_soldered.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spyspy board design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
