If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying ? I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on the market now.
First, crack open that LCD, and look what’s inside. I desoldered the wires, and took note on how they were connected. The LCD operates on around 12v and my RX5808 pcb has the voltage regulator on it, so you can power it from the same 12v.
Although this LCD has 2 input channels, I only chose to use one. You can solder a wire on that second pad and leave it hanging out of course ? I removed the three LCD buttons, so there is no way of switching between inputs. Take note that the LCD defaults to the active source on startup.
Next thing I did, was to mock up all the guts that Im going to put inside the LCD.
The whole electronic installation is really straight-forward. The blue pcb is the Charging module, small Green one is 12v booster. Connect the battery to the charging module, also connect the same wires to Booster module. Connect Booster output to LCD board and FPV board. Throw in a switch between charger and booster and voila! we’re done. Not hard now, was it? ?
Fix everything inside with kapton tape and hot glue. The back of the LCD panel is all metal, so you might want to put some stickers on it, or spray it with pcb protect spray. Be creative. B. E. Creative. You can see the DirtyPCB shipping information sticker I used ?
The neat thing about RX5808 pro is that it has spectrum scanner, and RSSI calibration (btw, that switch on the fpv board? switch between config and camera screen).
