MPP Solar MPI 10k Modbus Card DB9 Adapter
thingiverse
This is an adapter to make the second serial port of the MPP Solar MPI 10k and identical devices usable in form of a standard DB9 female connector. Unfortunately I don't know where to get this specific connector. I had it laying around and so I used it. I guess it's this one: https://www.usconverters.com/db9-screw-terminal-header-for-xs202 Instructions for the build process: I hammered flat a solid wire of 0,8 mm diameter and used them as goldfingers for the Modbus-Adapter-Card. 2 parts (Goldfinger_Befestigung.3mf and Slot_Befestigung.3mf) have to be superglued onto the card (see images). It's a bit hard to get in all the flat pieces of copper, but when it's done, it works flawlessly.
