Description

I bought the stepdown USB modul on ebay. Search for “stepdown USB modul” an compare the images.
I updated the part, the new board size is 19,2mm x 38,5mm

Need one M3x6 screw.

I mounted it on the right PSU, there is a free power port and the cable for the camera needs not to be so long. See pictures.

My printsettings:
Profile 0,2mm fast, for the infill I choosed gyroid. Prusament PETG black matte.
