Yes. ESP32 supports CAN and these are featured S3 boards.

@alveron Sometimes...this depends on the sketch that is running and other Arduino environment conditions...you need to manually enter Upload Mode.
Press both Reset and Boot and release the reset first. You will lose the Arduino serial com and you need to re-select it.
Once you have a stable environment it may not require the sequence, just Upload!
You must select USB CDC On Boot: "Enabled" to get serial from your sketch to your computer.
ADC in ESP32 is very poor. I don't have a T7-S3 to test, just check the Diagram and other Internet sources. There will be data noise and poor accuracy.

@hosky well, you could use the esp32 built in ADC to read pin 4 bat volt, or wire the 5V pin to a voltage divider and then to a GPIO, such as 16 and digitalRead it.

@etolocka Well, Ernesto, if the returned value is saying that the battery is 100% of 4.2 volts...I think you are THERE!
I do not use Python, have a board like yours or ever monitored battery voltage, so I am no expert, it looks like you are OK!

@etolocka The ESP32 is notoriously bad at ADC function, so...this is just a rough estimate of your battery life, 'for your information'

@vitorxlima Easy! Put a diode in series with the non-rechargeable battery to allow the battery to dis-charge and run the board but not allow the USB to pass current to it.

@whippe Interesting!
hmmm...I am way out of my depth here.
The PeakCan seems to be CAN to USB.
Do you have an example sketch to base this on?
The ESP32 connects to which end, the USB or CAN?
Does the equipment offer automotive style OBDII communication?
If you have the time, I'd like to know!

@mrquickie Hi! What program IDE are you using? Arduino?
To enter Upload Mode:
press Boot and hold it, press reset and then release, then release Boot and go it into "Upload Mode".

@whippe
Hi, sorry for the delay.
Are you still working on this problem?
If so I will ask more questions!
Also: What is your aim, trying to do!?

@whippe
Hi!
What CAN transceivers are you using?

What external CAN device are you trying to talk to?

@mustangproject Great news. If you hold boot and then press reset, and release reset, then release boot that will stop the MCU from executing your program and enter Download Mode and perhaps too busy? This is good to learn.
The i2c cable thing is just weird!!!
