How do I get my pc to recognise ESP32 boards

Other Hardware 3rd Party Boards

When I plug an ESP32 board into the usb socket, the arduino IDE does not recognise a port.

I have heard of a Silicon Labs download for this but do not know where to finf it.

which ESP32 ?

That's the name of the WiFi module on your board. I have marked it below in red.

What you need to know about is the chip I have marked in green. That is the chip that interfaces with your PC. What can you read on the top of that chip?

have you loaded the ESP32 board manager?

if you have, click on Tools >> Port WITHOUT the ESP32 plugged in. Note what ports are available

Then plug in the ESP32 and note which new port shows up. connect to that new port at 115200.

note that Arduino IDE loads on Raspberry Pi 4s and 5s, but the ESP32 manager bails and fails.

Also make sure that you are not using a charge-only USB cable.

I have three of these chips from AZ Delivery

The top lines are too indistinct. but the next 3 lines are (as far as I can tell) CP2102. FPC02K, 2320X

I have loaded t5he ESP32 board manager

No ports show up with or without the ESP plugged in.

In device manager line shows up in “other devices” Saying “CP2102 usb to uart bridge controller”

Hi @Jim49. Download the driver for the Silicon Labs CP2102 USB chip from the chip manufacturer's website here:

https://www.silabs.com/software-and-tools/usb-to-uart-bridge-vcp-drivers?tab=downloads

Then install that driver. After doing that, the board should produce a serial port you can select from Arduino IDE's Tools > Port menu.

All sorted now thanks everybody.

You are welcome. I'm glad it is working now.
