AI Thread Summary
The discussion centers on the challenges of uploading firmware to an ESP32 system with a built-in USB port. The user seeks guidance on creating a USB adapter for a Wi-Fi ESP32 board with a camera peripheral. It is noted that building a DIY USB interface can be complex, with references to USB standards available online. Suggestions include contacting the board manufacturer or joining a user group for support. The conversation emphasizes the importance of learning through the process of assembling the adapter.

TL;DR Summary
How can I breadboard an assembly to upload firmware to easp32 via usb?
I've been screwing around with an embedded esp32 system and have successfully flashed a few firmwares. The trouble is, my particular hardware has a built in usb port. For my next project I want to use a wifi esp32 board with camera peripheral. There are quite a few of them on Amazon and a minority come with a usb adapter. So I'm wondering what exactly I'd need to do to successfully assemble a usb adapter on a breadboard. Aside from being able to use more boards it would be nice to learn something.

Many thanks in advance for any help

A do-it-yourself USB inteface is, well... complicated. The Standards are here:

5 pages of 50 per page.

(above found with:

Your best bet is either contact the board manufacturer or find a users group for the board.

There are, however, USB interface chips made to connect an I/O port to USB... I don't remember any details though, it's been a quite a while since I've looked at one.

Good Luck!
And please let us know what you find.

Cheers,

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
