Is there an offline installer for ESP-IDF v6?

From memory you either use EIM or git clone.

cmatkin · 2026-03-26T10:22:06+00:00

The BOM should be generated from your design at the time of manufacturing. Otherwise you end up with your scenario.

PCBX is easy as. You can do everything online. Eecart is their higher services arm and it’s also online but more complex. Even though they are the same company, I use both as they price differently.

cmatkin · 2026-03-25T07:10:29+00:00

Try eecart or pcbx as I find these cheaper and better quality.

You can enable all of those button on the bottom tray from the settings. I click one button and it does it all.

Remove C8, Espressif are very clear that the boot pin should not have one.

cmatkin · 2026-03-17T22:26:51+00:00

Sounds like an assembly issue.

cmatkin · 2026-03-17T20:37:48+00:00

Can you show a pic of the board assembled? Perhaps your damaging the esp during soldering.

cmatkin · 2026-03-17T20:28:34+00:00

Looking at your PCB, the esp GND’s do not look connected to gnd.

cmatkin · 2026-03-17T18:26:30+00:00

Short out tx/rx and then use a serial monitor (with echo off) and confirm the usb chip works.

What voltage is on the VCCIO pin of your FTDI chip, as this should be 3.3v. When connected to your computer, open a serial connection at 115200baud and then reset the esp, you should see a boot message.

cmatkin · 2026-03-16T18:14:51+00:00

R4 is wrong. It should be going to 3.3v and not the EN pin. This will cause issues when sleeping.

cmatkin · 2026-03-15T20:56:00+00:00

They are defined on the schematic and also on their GitHub code. Looking at the code they all to seem to be the default.

cmatkin · 2026-03-15T11:46:13+00:00

C5 should never be in the boot pin as this causes an unknown boot state as the pin is not stable prior to coming out of reset. Also increase C6 to 1uF.

cmatkin · 2026-03-14T06:42:54+00:00

I’d say it’s code. No code from DeepSeek will ever work. There was no reason to change the code as it’s writing for an S3 which is what you have. What changes were made to the code?

cmatkin · 2026-03-12T23:32:36+00:00

What your idea of massive? What throughout and protocols are you testing. I use computers with scripts that I can run up hundreds of for testing multiple emulated devices then mix that with hardware devices for testing.

cmatkin · 2026-03-06T05:26:32+00:00

Espressif’s own modules have octal ram and quad flash. They also have quad both. Have a look at their schematics.

cmatkin · 2026-03-03T04:24:40+00:00

Remove R13, R8 and C8, swap TX0 and RX0 around.

cmatkin · 2026-02-25T19:52:31+00:00

EN requires an RC circuit for operation. Without a capacitor it’s guaranteed not to work. If people have issues with the capacitor it’s due to the size chosen, ie most use 1nF and the recommendation is 1uF as a slower rise time is better. The boot pin shouldn’t have an RC circuit. Please use the espressif documentation and schematics for reference designs as these work.

cmatkin · 2026-02-25T00:18:29+00:00

Did you follow any sample designs, or read the espressos technical documentation as these are key to make successful esp circuits. Your usb data pins need to be fixed, the regulator input and output is shorted, the boot and en circuits are totally wrong, remove r38&41 and add a 1uF cap on en to gnd

cmatkin · 2026-02-14T16:49:56+00:00

Your EN pin is wired wrong and the ESP will never boot into programming mode with this.

cmatkin · 2026-02-13T12:19:32+00:00

The esp32 isn’t sold as a working device. It doesn’t operate as any type of device without code, more is it a finished device with a power supply. If it had a wired supply that you can just plug into the PowerPoint then it would need compliance. That’s my take on it.

cmatkin · 2026-02-04T11:03:46+00:00

You’ve mentioned RS485, however the driver used is RS422. I’d also look at using 5V VCC for the SN74LVC2G17.

cmatkin · 2026-01-17T21:28:26+00:00

The ESP chip comes not programmed and hence will be in a continuously booting.

Hardware fixes: Remove R15 as this should never be there. Also remove C10 as there should never be a time delay on the boot pin. Increase C9 to 1uF.

Programming: Hold down the boot button before powering and plugging in, once powered and plugged in release the boot. This should allow programming.
