WebThe CAN bus was developed by BOSCH (1) as a multi-master, message broadcast system that specifies a maximum signaling rate of 1 megabit per second (bps). Unlike a traditional network such as USB or Ethernet, CAN does not send large blocks of data point-to-point from node A to node B under the supervision of a central bus master. Low speed CAN bus: This standard enables bit rates from 40 kbit/s to 125 kbit/s and allows the CAN bus commmunication to continue even if there is a fault on one of the two wires - hence ...
