CAN-Bus¶
Fault-tolerant Low-Speed CAN is up to 125KBit/s.

|---|---|---|---|
| 1 Mbit/s | 25 m | 1,5 m | 7,5 m |
| 800 kbit/s | 50 m | 2,5 m | 12,5 m |
| 500 kbit/s | 100 m | 5,5 m | 27,5 m |
| 250 kbit/s | 250 m | 11 m | 55 m |
| 125 kbit/s | 500 m | 22 m | 110 m |
| 50 kbit/s | 1000 m | 5 m | 275 m |
| 20 kbit/s | 2500 m | 137,5 m | 687,5 m |
| 10 kbit/s | 5000 m | 275 m | 1375 m |
According to this site,
500kbit/s is common for most automotive applications. Works for me.
