Gravity: CAN to TTL Communication Module with SLCAN Protocol - DFRobot TEL0150

This is a CAN-to-UART and USB 1.0 communication module that is compatible with both 3.3V and 5V. It supports the CAN 2.0 protocol and incorporates the SLCAN command, eliminating the need for you to concern yourself with the complexities of the CAN protocol. By simply sending AT commands, you can engage in CAN data transmission and configure its functionalities.

This module not only provides a UART interface but also integrates a USB interface, eliminating the need for cumbersome conversions between USB and UART during data debugging. Connecting it to your computer via USB allows for convenient data debugging through a serial assistant. This feature proves particularly handy when deploying the module on-site for debugging purposes.

The module offers a configurable CAN baud rate range of 25K–1 Mbps, supporting a maximum rate of 2 milliseconds per transmission and ensuring the delivery of 500 data packets per second without any loss. Its stable and reliable communication capabilities significantly reduce the likelihood of errors in your project and streamline the project debugging process.

Additionally, the module is equipped with data communication indicators and a 120Ω resistor jumper. These design details serve to enhance the efficiency of your project development and validation.
