B02-K Classic: PIC18F25K80 Dual-Board Vehicle Communication System
The B02-K is a high-performance Bluetooth diagnostic adapter engineered for those who demand a stable and proven vehicle communication system. Unlike basic scanners, the B02-K features a classic dual-board architecture powered by the legendary PIC18F25K80 main control chip. This robust hardware design ensures superior signal processing, high-speed data transmission, and the ability to handle complex diagnostic commands without interruption.
Whether you are performing professional workshop inspections or integrating diagnostic software, the B02-K offers the rock-solid reliability of a traditional circuit layout in a modern, wireless form factor.
Why the B02-K is the Professional Standard
Legendary PIC18F25K80 Chipset: At the heart of this device is the high-speed 25K80 chip, recognized globally for its stability and broad compatibility with advanced diagnostic protocols.
Proven Dual-Board Architecture: The multi-board design provides better heat management and a more resilient circuit layout, ensuring consistent performance during long-term diagnostic sessions.
Full 9-Protocol Support: The B02-K supports all standard OBD II communication protocols, including SAE J1850 (PWM/VPW), ISO9141-2, and CAN bus. This makes it a universal vehicle communication system for a wide variety of gasoline and diesel vehicles.
Ultra-Compact Blue Design: Measuring only 49mm, this "plug-and-play" device fits securely in the OBD II port without obstructing the driver’s footwell or dashboard operation.
Stable Bluetooth Connection: Experience reliable, wireless data transfer directly to your smartphone, tablet, or laptop, giving you the freedom to move around the vehicle while monitoring live data.
Core Diagnostic Capabilities
Error Code Management: Instantly read and clear Diagnostic Trouble Codes (DTCs) to identify engine faults and reset the "Check Engine" light.
Live Data Monitoring: Stream real-time engine metrics, such as RPM, fuel system status, and coolant temperature, with high-precision accuracy.
Emissions Testing: Quickly verify I/M readiness status to ensure your vehicle is prepared for annual smog inspections.
ECU Information Retrieval: Access VIN, CALID, and CVN data directly from the vehicle’s computer for accurate record-keeping.
