Adafruit CAN Bus FeatherWing - MCP2515 Spedizione:4-6 Giorni Beacons do not need toCAN Bus is a small scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet. CAN is 2 wire differential, which means it's good for long distances and noisy environments. Messages are sent at about 1Mbps rate you set the frequency for the bus and then all 'joiners'
