Help!
Holybro Atlatl HV 5.8 25/600mw (Cant connect)
Hi all. I bought a Holybro Atlatl HV 5.8 25/600mw and set it up. It was working completely fine the other day, haven't flown for a couple of days now due to the weather. I powered it up, blue blinking led every second as usual. However there is no video. I tried replacing the camera with a new one out of a box that does work. But still no signal from my receiver.
I've flicked through all channels of my RX but no luck. And I can't really see what channel the VTX is on, having no screen and just 1 button without the VTOSD. I've decided to attempt a diagnosis but with such comes finding the datasheet for the VTX module. I've checked the main power pins and its getting power and gets slightly warm. As it would do when its working. However I cannot seem to follow the video feed connection from the plug to the actual Transmitter module (Shielded module) I'm thinking that they might be a break between the video plug and the actual module on the board. If anyone could help me find a datasheet to show the pinout of the actual VTX shielded module that would be a life saver. Or any other help would be great. |

Update: I don't think that VTX module above board is dead. VTX module and Atmel based control circuit (one who decode Tramp to channels and PIT mode for VTX) have separate voltage regulators. Our dead one is 3.3V BEC below board. |
