Analog Devices Inc. MAX33012ESHLD Shield is a fully assembled and tested printed circuit board (PCB) that demonstrates the functionality of the MAX33012E. The MAX33012E is a high ±65V fault protection, ±25V common-mode input range, ±25kV ESD Human Body Model (HBM) controller area network (CAN) transceiver. The Mbed/Arduino shield can also be used as a standalone evaluation board. The shield features a digital isolator, which is used as a level translator between the CAN transceiver and the controller interface.
