Is it normal that my minimOSD (micro version) and my VTx (aomway 200mW) producing much heat?

I have seen builds with heat sinks on top of the aomway VTx, is this necessary? Are there other ways to reduce heat?

The voltage of the OSD is slightly above 5V (5.12V), should i improve the voltage source?


Thanks for your help

Yea the micro minimosd does get quite warm.. VTX can also get warm... Just make sure you use an antenna and the antenna is the correct connector

Don't power on for too long on the ground.. You are fine with decent air flow when flying

I have an Aomway 200mW and it gets hot as well.

So it isn't a big deal i guess. Thanks for your reply

Oscar, you seem to be very knowledgeable. On one of my builds I'm setting up an OSD stacked on an naze32. Flashed with base flight. Flash the OSD no problem . I set all the fonts and everything on the GUI no problems. When I plug in the stack and then plug in the micro USB to the OSD GUI, it just says reading, I don't have a cam yet still waiting so I can try it that way. I also have a micro OSD that I flashed and it works fine but I haven't tried them yet with Cam and transmitter. I should be getting my cam and transmitter in a day or two is the OSD supposed to read with gui on the stack? I'm not real sure on how to wire it I keep seeing different things online.

What do you mean "read with gui on the stack"?

You connect Minimosd and FC TX to RX, RX to TX.. Connect GND as well

I need help I've been racking my brain with this and I just can't get it. this is a br OSD on naze32 stack. have it wired right I've changed a few things in Arduino butt I get this Chinese writing on the monitor any help on this anybody. MW R1.6 and I'm running the latest baseflight. Everything reads good on the editor. I don't know what gui is either. I have a Micro as well but like this stack. Don't need to load fonts right??

just replied to your thread.

I just found this cool little enclosure made by Oscar? Is this the same Oscar on this forum? I want one! The enclosure I mean!

Lol different person.. I think it would be a good idea if its on a RC car haha... With the airflow on a quad copter, you should not have any problems.. Unless you leave the quad powered on the ground for extended length of time

And if its getting hot in the air, you need more uptilt on the cam

You could get a small and light aluminum heatsink and attach it to the VTX, if you really wan't to.
