DIY OSD

I’ve built a DIY OSD based on Dennis Frie hardware and software released on rcgroups forum. I’m fairly happy with the results, the osd actually work. I do have some issues, but nothing serious. I have GPS, voltage sensors working as they should so far and am planning to add a current sensor and possibly rssi as well.

Top side not much to talk about. It’s an arduino pro mini 5v unit.

The GPS in the picture is not the one I’m using so far, but I will move over to it in a few days I hope, if I find the time. Main problem is that the GPS requires 3.3v,I’m running everything on 5v at the moment. I’m currently using a ublox neo7m from banggood. The picture shows how I hope to mount the GPS approximately though, depending on how I plan to mount OSD in comparison to the video link and the camera… GPS and video link should be mounted as far away from each other as possible, but OSD needs to be close to the video cable.

The bottom side. Most of the components have been sandwiched between the PCB’s. Some of the routing is a bit stupid but I’ll see if I can fix it so I can fit the current sensor somewhere on the bottom as well.
