    Hey all! I am currently working on a micro fpv quadcopter, and I plan on using this video transmitter:
    http://www.banggood.com/FPV-5_8G-200mW-Wireless-Audio-Video-Transmitter-Module-TX5823-p-84780.html
    It says that it only accepts 3.3 volts input, however I am using a 1s lipo battery to power it. A 1s lipo has a max voltage of 4.2 and minimum voltage of around 3.3-3.7. Am I ok to use the battery straight to the transmitter, or do I need a voltage regulator? If so, any suggestions? I would like to keep it as small as possible, but also cheap. Thanks!

    Where did you read that? From your link #4 Operating Voltage 3.5 Min., 5.0 Typ., and 5.5 Max. That is what I see in the data.

    Oops looks like I didnt read carefully enought lol. Under the description it says power supply voltage: 3.3v so I figured that it couldnt go over that. Thanks!

    yea another reason I was skeptical. Do you think 4.2 volts will be ok?
