(3pcs) Matek Micro BEC 6-30V to 5V/9V Adjustable Step-Down Regulator for 4/5 inch 220mm 210mm 250mm 6s Carbon Fiber FPV Racing Quad Frame X Quadcopter Like Martian II 220 QAV250 QAV210 X210

Great great value buy,easy to install, works great

These are really nice BEC's they are tiny and of high quality. I used these to step down battery voltage to power my flight controller as the 4 in 1 ESC that I used for my drone build did not have any 5v bec built into it. This is working perfectly for that use. As always Matek Sys products are of high quality and last a long time.

Used this to step 25v down to 9v for a HD VTX. Picture is clean, highly recommend this product.

Excellent little Vreg. Low ripple and provides enough amperage you keep circuitry / logic boards running fine. Probably not enough to drive full sized servos not charge any USB device, so don’t try.

You found them! These are the perfect tiny 5V BEC. I tried a bunch of different tiny 5V BECs. They all work fine but these are the tiniest. Will comment here if I find smaller ones. In the meantime, these are it!

I've used several of these across multiple FPV drone builds. They are excellent for stepped down power from VBat for those electronics that need lower (and clean) voltage.

Had a couple of these in my FPV quad wired up to my DJI air unit and all of them failed after a certain amount of time causing me to lose video while flying. Removed the BECs and haven't had any issues since. Don't use these if you want your stuff to work.

These adjustable regulators are perfect for powering all sorts of low-voltage devices, not just model aircraft parts. They're great for powering small devices like single-board computers from a wide range of DC inputs.
