Another place to buy the CM4 Pi-Storm break out boards from…
https://www.tindie.com/products/retrofletch/pistorm32-cm4-adapter-board-io-board-cable/Look good quality and should reach the right customers address in good time too….
Also this seller actually uses the following disclaimer:
Pistorm32 for A1200 have better chipram access then the normal pistorm models for A500 / A600 and using the CM4 offers much better overall performance.
This is still a project under active development and you can find info on the github here : https://github.com/PiStorm/The projects is fully Open Source and for most up to date information and support you need to join the pistorm Discord.
You are Welcome… 👍🏻
