This time, i will show you how to make a cheap enough FPV Monitor. Things we need are:<\/p>\n\n\n\n
- 4,3 inch or 5 inch monitor (depending how big you want to use)
can be bought here<\/a> for Indonesia market<\/li>- VRX Module with antennas (can be cheap AKK (here is the link<\/a>) or Eachine Pro 58 (here is the link<\/a>) or even top end receivers that you can found on the market)<\/li>
- BEC (any volt to 9V\/12V or step up from 7.4V (2S) to 9V\/12V)<\/li>
- Solder (and also soldering skills)<\/li>
- Silicon wire\/cable (30 AWG) would be enough<\/li>
- switch if you needed<\/li>
- patience \ud83d\ude42<\/li><\/ul>\n\n\n\n
or if you’re outside Indonesia, you can check links below:<\/p>\n\n\n\n

- AKK Receiver (link<\/a>)<\/li>
- BEC (link<\/a>)<\/li><\/ol>\n\n\n\n
\n\n\n\n#1 Step<\/h2>\n\n\n\n
As standard automotive monitor like this, they often disable its “snowscreen” screen and replace it to a blank screen or blue screen if there is a weak or no video signal present. in FPV we dont need that, we need a “snowscreen” so that we can still see a picture even if the signal is low or disturbed.<\/p>\n\n\n\n

no signal’s “bluescreen”<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n To disable the bluescreen mode, just press a hidden menu for this monitor by pressing the menu button (3 key behind the monitor) this combination code to access the factory mode the combo Menu,+,-,-,+,+ or Menu -,+,+,-,- \ud83d\ude42<\/p>\n\n\n\n

Dissasemble your 4.3 inch monitor.<\/p>\n\n\n\n

<\/figure>\n<\/figure>\n\n\n\nSince monitor we use is designed for automotive, it should be easy in handling voltages (i think it may took minimum 9V to 14V as maximum) (update, i can powered it up using 2S battery tho<\/em>)<\/p>\n\n\n\n
As you can see above, we need to: <\/p>\n\n\n\n
- desolder the AV in cable and also Voltage in cable (as later we don’t need it, because we need to solder it directly to the receiver and PDB\/BEC)<\/li>
- unplug the lcd-adjustment keyboard (don’t trash it because we will need it somehow later \ud83d\ude42 trust me)<\/li><\/ul>\n\n\n\n

most of all fatshark module have the same pinout<\/figcaption><\/figure>\n<\/div>\n\n\n\n \nPrepare your VRX Module, and find the designated pins to be used later.<\/p>\n\n\n\n
pin we need are:<\/p>\n\n\n\n
- 5V (later will be connected using PDB\/BEC<\/em>)<\/li>
- Gnd (Ground should be in a loop with other parts<\/em>)<\/li>
- Audio (if your VTX support audio)<\/li>
- Video<\/li><\/ul>\n\n\n\n
