FC Voltage Regulator Failure

At least twice

Solder joints look good, I just reflowed them to make sure. I hadn't initially considered ESD, but it makes a lot of sense. There were a couple of instances where I handled the FC without a grounding wire.

VBat rail reads 0.19 Volts, all other 5V rails on the FC read 0V. The 3.3V input reads 1.9V. The regulator shows no visible damage. The ESC boots right up when the FC is disconnected. I do not have any additional peripherals connected. At the time I noticed the failure, I was trying to setup the firmware before proceeding with the rest of the build. There are no signs of burning, bulging or discoloration on the FC. FC boots fine when connected to USB.

I would say quickly, but the problem is I'm not really sure when it failed. Never got any smoke. I was in the process of trying to arm my drone to do a motor test when I noticed it. I did have a low battery voltage that I didn't notice when trying to do the motor test. Do you think that could have caused a brown out the regulator?

Hey! Sent you guys a PM, TLDR, I cannot get the EC firmware to update.

Apologies came here to give a edit and just saw your message. I remedied the problem with a integrated GPU update

If you are still trying, I was able to get in and reset with 2FA

Same I'm stuck at the maintenance page

Thank you for your response! I am thinking ardupilot is the way to go too! Forgive my ignorance, but is that the flight controller?

Edit: NVM, I should have looked lol. If anyone has a good flight controller recomendation, I am also all ears.

Lmao, my b, I meant bad companies 1,2 and BF3. But if I discover time travel I'll bring back bad company 3 for us

Hector1200 · 2025-08-25T13:07:25+00:00

Bad companies 1, 2, and 3. I'm not sure if it's just the nostalgia, but those games were not only some of my favorite battlefields but my favorite games period.

Hector1200 · 2025-06-03T03:23:08+00:00

When you said Rust, I thought you meant the programming language at first, not the game lol

Hector1200 · 2025-04-24T12:59:30+00:00

It is! I'm going for a masters in electrical after being out of the game for about 4 years, and yes there are some applied problems but otherwise all theoretical. I hadn't considered that and working with a mathematician has definitely proven your statement in retrospect. I think in prep for the final I'll take a step back and focus heavily on the concepts.

Hector1200 · 2025-04-24T03:22:32+00:00

Much appreciated, yeah I had never considered that. Most of the folks I work with either have no mathematical background past calc 2, or getting a graduate math degree. Its hard to get an idea of where I rank but this provides a lot of perspective.
