MCP2542 is designed specifically for high-speed CAN FD applications with communication speeds of up to 8 Mbps. Longer than usual BUS lengths are supported thanks to the improved maximum propagation delay.
The board has a standard RS232 port for CAN communications.
MCP2542 click communicates with the target board MCU through mikroBUS UART interface with an additional StandBy pin (STBY, in place of default mikroBUS AN pin). Two additional pairs of pins on the right edge of the board offer separate UART connection as well as a CAN interface.
The board is designed to use either a 3.3V or 5V power supply.

Benefits that CAN bus brings in comparison to other serial protocols are already explained at first CAN bus article. Most of that benefits alongside with simplicity of the UART protocol can be found on MCP2542 click board. This click board can be observed like hybrid of CAN and UART which brings all the best from both.
