Boardoza TPT71050 Isolated CAN FD Transceiver Breakout Board
The Boardoza TPT71050 Breakout Board is a compact and robust isolated CAN FD transceiver solution designed for reliable communication in industrial, automotive, and embedded systems. Built around the TPT71050 isolated CAN transceiver, the board provides galvanic isolation between the logic side and the CAN bus side, helping protect sensitive electronics from electrical noise, ground loops, and voltage transients commonly encountered in harsh environments. Supporting both Classical CAN and CAN FD (Flexible Data Rate), the board enables data transfer rates of up to 5 Mbps while maintaining strong signal integrity and noise immunity. Its isolation barrier and selectable termination resistor make it ideal for industrial automation, motor control systems, battery management systems (BMS), automotive diagnostics, and other applications that require reliable long-distance CAN communication.
