Arduino Esp32-S3 can't find pin 35!

[Bawan007]

Hello uhi22....thank you for your work here.....

I'm using my Arduino nano Esp32s3 to connect to Savvycan to read my car's canbus, I tried to connect via GVRET, but for some reasons it didn't work....
So I want to connect via Wi-Fi but I can't find pin 35 on my bord to use the wifi field mode?
Please can you tell me to ground which pin.

I attached a picture of my board pinout below.

Thanks in advance.....

Hi, this is a completely different board. You can choose an other pin and change the code accordingly.

Thanks bro for the quick reply.....

Can I use the TJA1040 transceiver?

If yes, should I change anything in the code or install another library for it to work?

The TJA1040 needs 5V supply and has 5V logic levels. To use this on the ESP32, you need to connect the TJAs supply to 5V, and insert a 1k protection resistor in the CANRX line, to avoid that the 5V signal of the TJA drives high current into the ESPs CANRX pin, which is designed for 3.3V.
Using a 3.3V CAN transceiver like SN65HVD230 would be the clean solution.

Great, I think I'll do just that.

Thanks for the help........
