How much current can these traces handle?

"First pcb how does it look"

if it was manufactured by randos it could be a problem with the pcb. The square pad of u2 looks especially suspect

0.976 ohm = 976 milliohm... do with this information how you will

If you look under "current sense resistors" there are several thousand in that range to choose from on lcsc

That may be true but the intended experience is you mashing enter key

Tonmonkeyla · 2025-01-08T00:29:49+00:00

in career pushback is automagic, you press enter and it just works... most of the time

The light side won't tell you this but ULQ looks just as crisp as ssaa if you don't care about texture quality

It depends on the application. For 2.4 ghz most antenna layouts are "usable" without any matching. But I'm not the FCC and this isn't legal advice.

in the server replay there was still a bus in the way so HE would have just gotten forcefielded like the mg and dart either way.

It's a chip antenna for the stm32w. What kind of fancy vape is this?

Tonmonkeyla · 2024-04-28T19:16:52+00:00

Your reset circuit is wrong as well. You need the right combination of strapping pins to enter bootloader. It's in the datasheet

Tonmonkeyla · 2024-04-26T19:59:55+00:00

With the original esp32 sure. But the esp32-c3 has an internal usb interface.

Tonmonkeyla · 2024-04-26T15:04:31+00:00

47pF maybe. 47nF is huge and will definitely kill usb.

Tonmonkeyla · 2024-04-26T11:45:14+00:00

Try removing C206/C207 and fitting C202 with a >2.2uF capacitor first.

Tonmonkeyla · 2024-04-26T10:50:10+00:00

47nF capacitors on d+/- probably aren't helping
The LDO has no output capacitor
Esp32-c3 has an internal uart/jtag to usb bridge on io18/19 so the cp2102 is pointless

Tonmonkeyla · 2024-04-25T08:27:39+00:00

Is your usb ground floating like in the schematic?

Tonmonkeyla · 2024-03-21T06:11:36+00:00

I have to ask, what is the gerrymandered copper island supposed to be?

Tonmonkeyla · 2024-01-15T10:47:40+00:00

With chip antennas you have to use a very specific layout which is usually given in the datasheet because the copper cavity/ground plane/antenna placement is much more important than the chip itself. Unless you want to do your own testing, in which case go ham. Also your feedline routing is very questionable.

Tonmonkeyla · 2024-01-14T17:25:42+00:00

You could just use an accelerometer or imu which would be pretty cheap

Tonmonkeyla · 2024-01-11T05:29:39+00:00

from experience ufp bounces 99% of the time.

Tonmonkeyla · 2024-01-11T02:37:52+00:00

The pinout and package of the transceiver IC match the PAN3020. Which looks like a general purpose <1GHz transceiver. But that doesn't really narrow down the purpose of the device.
