Hey Again,
maybe this is also important to know.
I used this CAN Transceiver Board
KNACRO SN65HVD230
Bought them here https://www.amazon.com/KNACRO-SN65HVD230-Communication-transceiver-Arduino/dp/B01ILU2WP6/ref=cm_cr_arp_d_pdt_img_top?ie=UTF8
So the SN65HVD230 is already wired on a breakout board an I only added the capacitors in between.
Greetings
