Quick note how to fix SN65HVD230 can module:
I waste hours trying to figure out why my CAN setup doesn't work and only after I read f$% datasheet and check all voltages with multimeter I found that standby pin voltage is above 0.75 volts, that means manufacturer mistake.

After I short-circuit this resistor everything start working as it should, so if you have same module just desolder this resistor:

and short the pads together

I hope you reading this before hours of troubleshooting
