Mini OSD Module On Screen Display for APM APM2.8 Pixhawk PX4 Flight Controller

I broke the first one in a crash. This one will not connect to mavlink. I've tried every osd config I can find. The full 700 page pixhaek parameters list. At least 40 different setup videos. Pertinent wiki pages. Conductivity check on all wires. No mavlink connection is the only display I get. So the osd board obviously works to some extent.May be a wrong setting on my part, but I was able to get the first board working fine. So I'm just gonna write it off as a loss. Not worth the hassle of returning.

There is nothing wrong with this product and I would order it again.

2.4 software doesn't work only old 2.2 works

Good
