Gravity: CAN to TTL Communication Module with SLCAN Protocol

The DFRobot Gravity TEL0150 is a CAN-to-UART and USB-1.0 communication module that supports CAN 2.0 and the SLCAN protocol. Thanks to the SLCAN protocol, CAN frames can be sent and received using simple AT command syntax, without having to directly address the complex CAN protocol layer. In addition to the UART port, the module features a built-in USB socket, so no separate USB-to-UART converter is required for PC connection.

Features:

• CAN-2.0 compatible with SLCAN protocol – send and receive CAN frames using AT commands without direct CAN protocol knowledge
• Configurable CAN baud rate from 25 kbit/s to 1 Mbit/s; default configuration 500 kbit/s for up to 500 lossless packets per second
• Built-in USB-1.0 socket for direct PC connection without external USB-to-UART converter – ideal for on-site debugging
• Dual voltage compatibility 3.3 V / 5 V at UART interface; configuration parameters retained after power interruption
• Supports 11-Bit Standard Data Frames, 29-Bit Extended Data Frames and RTR Frames according to SLCAN specification
• Compact design 37 × 47 × 11.6 mm for easy integration into robots, vehicles, and industrial controls

Application Examples:

• CAN bus communication in robots and AGVs for motor controllers, sensors, and actuators on a common bus
• Development and debugging of vehicle electronics with CAN 2.0 protocol via simple UART/USB connection on PC
• Industrial control applications in lighting systems and small vehicles with standardized CAN bus
• Prototyping and integration of CAN-enabled industrial components with Arduino or ESP32
• PC-based CAN bus monitoring and protocol analysis via USB without additional hardware adapter
