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 up to 5 Mbps, this breakout board is ideal for modern automotive and industrial CAN and CAN FD systems.
Designed for robust operation in harsh environments, the ATA6561 offers excellent EMC and ESD performance, low-power standby mode with CAN wake-up capability, and passive bus behavior when unpowered. Because it supports selectable voltage levels (3.3V / 5V), it is compatible with many microcontrollers, making it suitable for embedded systems, automotive, and industrial automation projects.
