Feature：
1. The PCB uses high-end 8 layers of 2oZ thick copper, which has stronger over current capability and good heat dissipation.
2. MOS adopts imported 30V high current resistance MOS, long life and strong load capacity.
3. Using industrial grade LDO, high temperature resistance.
4. Using high-quality Japanese Murata capacitors, strong filtering performance

Works well so far. I have two of them and I am still trying to figure out if it works well with BetaFlight V4.5. It is working well with V4.4.3 though. CPU loading seems to be much higher with V4.5

Good bang for the buck
My new favorite FC. You have the pinout in the box and I haven't had any issues with it so far. I am currently using 4 of them.

Good AIO, I made a mistake and burned out another one i guess?
I purchased two, put Conformal Coating onto these board before soldering the pads, mind you I put one small layer near the pads then proceeded to put two more layers on the rest of the boards knowing I will be back to put more on.
I got a Cold Solder Joint on the Negative Terminal, I tried to solder it back on, kept on popping off, I proceeded to put more solder on and it seemed to be stuck, then I tested the FC and it wasn’t working.
So it’s Toast, I tested the USB, toast. So I was able to get my second one to solder “welded” I’ve been flying that for a week, did the same process, but went back and tried to clean more of the Conformal Coating off with IsoPropyl.
I damaged it within a week of owning it, contacted NewbeeDrone and they push it along to HAKRC. I’ve been talking to them for a week, they asked the same questions over and over, I had to repeat myself to them, send tons of photos, while they lectured me on the “three defense” sequence of conformal coating.
Yeah I didn’t tin up the pads first, but the amount of Conformal Coating I put on shouldn’t have caused it not to make a good enough contact?
So I was talking to their “support” email and I just realized it’s not worth it to RMS the board especially since they kept on being vague with their answers.
I got a bunch of their boards, but I do have the most problem with Conformal Coating and their boards and me burning them out when I build or transfer.
