Product description
TTL UART to CAN module. Equipped with a high-performance MCU, enabling communication between TTL UART and CAN after simple configuration. CAN parameters, such as the communication baud rate, as well as serial port parameters, can be modified using the configuration software. Use a USB-to-TTL converter, such as 41035672, for the initial configuration. If no configuration is required, the factory settings can be used.
Features:
- Onboard high-performance MCU and CAN transceiver chip, compact size, low power consumption, and easy to integrate
- Built-in TTL and CAN protocol conversion algorithm enabling data communication between TTL and CAN through simple configuration
- Supports 3.3 V operating voltage on the TTL interface and both CAN 2.0A (standard frame) and CAN 2.0B (extended frame) on the CAN interface
- Supports 14 configurable filter sets, allowing only CAN bus data within a specified range and type to be received through configuration
- Supports four operating modes: transparent conversion, transparent conversion with identifiers, format conversion, and Modbus RTU protocol conversion
- Supports offline detection and automatic recovery
- UART communication baud rate: 1200–460800 bps
- CAN communication baud rate: 10–1000 kbps, configurable
- CAN buffer for up to 1000 frames to buffer transmission data and prevent data loss
- Supports high-speed conversion. CAN transmission speed can reach up to 1270 extended frames per second with the UART set to 115200 bps and CAN set to 250 kbps (close to the theoretical maximum of 1309), and can exceed 5000 extended frames per second with the UART set to 460800 bps and CAN set to 1000 kbps
- Supports device firmware upgrade via TTL, making firmware updates and function customization more convenient
