SA-OBD
CAN Decoder Box
Compact vehicle communication interface for collecting CAN bus and K-Line data and converting vehicle protocol data into UART-format data for connected host equipment.

Connect Vehicle Data With Your Application
A compact CAN decoder interface designed for vehicle diagnostics, data acquisition and secondary application development.
Vehicle Protocol to UART Conversion
The SA-OBD CAN Decoder Box connects to a vehicle through a standard OBD-II connector or dedicated CAN bus connection and collects vehicle bus data. The collected information is converted into UART-format data for connection to host equipment.
- Standard OBD-II automotive communication
- High-speed CAN communication
- K-Line communication
- UART host communication
- Vehicle data acquisition and analysis
- Support for customized gateway interfaces
