MNT Reform Next takes the MNT Reform family's modular approach a few steps further: The motherboard doesn't have any exterior ports, instead it breaks out all important signals in groups to FPC and JST-SH headers. The connectivity to the outside is implemented via user-exchangable Port Boards that increase repairability, customizability and future proofing of interfaces. The motherboard provides the system controller (RP2040 based), main (multi chemistry) LiFePO4/LiIon charger buck/boost controller, main 5V and 3V3 power rails and the SOM…
