Hi, there is JST connection on my Vesc as( GND, pa4, pa3, 5V) can I use it as extra can bus(can-h. can-l )

You shouldn’t need an extra can bus. You can daisy chain canbus devices.

Would be helpful to know what vesc you have. As much as we’d like to, we’re no mind readers

also, what @Evwan said. CAN is a data bus, so you don’t need dedicated channels for each additional device (unlike UART)

TRONIC, as you can see can is divided in 2 and I couldn’t connect voyage to it

wdym by can is divided in 2?

can bus uses 2 wires. CAN L(ow) and CAN (H)igh
you connect those 2 pins via 2 wires to your voyage systems device, and in parallel on to your second vesc. a voyage system minnie actually has two can ports already in parallel to make that easier.

(concerns over can termination resistors are often ignored with small numbers of devices. )
