Mark, you should come to the klipper discord chat as the creator of this board, i see so many people looking for a futureproof solution or struggeling with undocumented boards or features they cant fix, if you showed people what could be achieved with your innovative solution i thoink you could have many converts. 64bit os & klipper, native RPI integration ( for timelapse prints, HQ cam etc, auto print from slicer to mailsail ( no sd cards or sneaker net), Direct disply capability with touchscreen over DSI connecter ( HD capable and much better than current serial displays) , only thoughts for the future is wether you have considered make v3 with a CM4 connector built in, solves the micro SD bootup ( use emcc) cost is low and performance even better !
i put a link to your project https://discord.com/channels/431557959978450984/601514366256283667/817684023052206100
