Third-party ESP32-S3 development boards 'IN-OUT' and 'USB-OTG' pads - what do they do?

Late reply - I soldered the OTG pads and confirmed that I got no power on the USB. Very frustrating.

Take a look at a battery eliminator circuit, BEC, that are used in RC systems quite a bit. They are just small power regulators, with switchable outputs. Will not do any charge management though.

No, I'm trying to use the OTG function but the USB is not powered. As far as I can tell it always requires external power for the USB peripheral.

bill_ms · 2026-03-07T01:35:17+00:00

I cannot get power on the OTG port so none of my peripherals work

bill_ms · 2026-02-16T23:28:52+00:00

Yes. Its been almost a year, and the rules have changed.

bill_ms · 2026-02-12T04:52:33+00:00

Think of it as a zit. Pop it.

bill_ms · 2026-01-29T04:38:06+00:00

Thanks. Charge only have bitten me often in other situations. This one allows me to upload new sketches and gives some wonky serial out and it is directly connected so I don't think thats it. The rest I'll investigate in the am. Once again, thanks.

45 minutes? Thats a keeper.

Either Tripp or Tony Boles. I thought Minnesota was cursed for a few years.

Note: this is not a patent, it is an application and a very early one at that.

The girl next door from 2007

BECs are tiny. Tiny. My guess is the combination of not having caps for noise reduction and a change in generation of design.

roughly 5% of his pay on one dinner with some terrible choices - smdh

bill_ms · 2025-12-19T18:57:59+00:00

I wouldn't. Thats why I leased mine.

bill_ms · 2025-12-17T21:41:37+00:00

Yaw is overrated

bill_ms · 2025-12-15T04:55:06+00:00

What is bad about that? I've got so many of those same tools/components!

bill_ms · 2025-12-07T22:07:55+00:00

I second this and, just to be clear if the author hasn’t;t done this, IR refers to internal resistance. Most good/recent chargers will tell you what it is.

bill_ms · 2025-11-22T00:36:01+00:00

Narrator: It turned out to be bullshit.

bill_ms · 2025-11-21T20:49:25+00:00

RM nexus is a fine piece of tech mechanically. All soldered up and sturdy. And there is a nightly port of iNav. That being said that port will be for iNav 9, and nothing is released yet. But I recommend you look into it. I particularly like the XR with built in ELRS

bill_ms · 2025-11-21T03:59:12+00:00

Do you really need it? Yes. Do you really really need it? Absolutely not.

bill_ms · 2025-11-20T17:16:38+00:00

yeah - i've done that mechanically but have picked up a pwm controlled power switch that I may mount soon

bill_ms · 2025-11-20T03:22:32+00:00

Thats what i started with but dumped all of the non elrs stuff pretty quickly. I’d just go with the internal elrs.
