Boardoza ATA6561 High-Speed CAN Transceiver Breakout Board
The Boardoza ATA6561 Breakout Board is a high-speed CAN (Controller Area Network) transceiver module built around the Microchip ATA6561 IC. It enables reliable communication between a CAN controller and the physical two-wire CAN bus. Supporting data rates of up to 5 Mbps, the board is well suited for modern automotive, industrial CAN, and CAN FD applications. Designed for robust operation in harsh environments, the ATA6561 provides strong EMC and ESD performance, a low-power standby mode with CAN wake-up capability, and passive bus behavior when unpowered. Its selectable 3.3 V and 5 V logic-level support ensures compatibility with a wide range of microcontrollers, making it suitable for embedded systems, automotive electronics, and industrial automation projects.
