TTL UART to CAN Mini Module
Compact Size | Easy Integration | Low power consumption
Features At A Glance
WS-TTL-CAN is a TTL UART to CAN module which is compact and easy to integrate, onboard high-performance MCU, with TTL and CAN conversion protocol, easily achieving UART to CAN via simple configuration.
- Onboard high-performance MCU and CAN transceiver chip, small in size, low power and easy to integrate
- Built in TTL and CAN conversion protocol algorithm, enabling data conversion communication between TTL and CAN via simple configuration
- Supports 3.3V operating voltage on TTL interface, supports both CAN 2.0A (standard frame) and CAN 2.0B (extended frame) on CAN interface
- Supports 14 sets of configurable filters, can only receive CAN bus data in specific range and type via configuration
- Supports 4 operating modes: transparent conversion, transparent with identifiers conversion, format conversion, and Modbus RTU protocol conversion
- Supports offline detection and automatic recovery functions
- UART communication baudrate: 1200bps～460800bps
- CAN communication baudrate: 10kbps~1000kbps, configurable
- Up to 1000 frames CAN buffer for buffering transmission data to prevent data loss
- Supports high-speed conversion, the CAN transmission speed can reach up to 1270 extended frames per second with the UART at 115200bps and CAN at 250kbps (close to the theoretical max value of 1309), and can exceed 5000 extended frames per second with the UART at 460800bps and CAN at 1000kbps
- Supports device firmware upgrade via TTL, more convenient for firmware update and function customization
