5 Boards that Make Rapid Prototyping Easy: Page 4 of 5

摘要

The controller area network (CAN) interface is quite popular among several different industries but a problem I have often encountered is that low-cost development board do not include a CAN transceiver on their development boards! This means that your microcontroller might support CAN but you don't have the correct physical layer in place to actually connect to a CAN bus! A low-cost CAN transceiver development board that I use is the Waveshare CAN board. This board provides the CAN high and low lines that are necessary for the CAN physical layer and then the CAN Tx and Rx lines that are needed by a microcontroller.
