WiCAN Pro is an unparalleled diagnostic OBD scanner meticulously designed to meet the advanced needs of automotive diagnostics. Powered by a dedicated OBD interpreter chip, it ensures comprehensive support across all legislated OBD-II protocols. With its ability to interface with three CAN BUS protocols and one SW CAN, WiCAN Pro offers broad compatibility, covering numerous vehicle makes and models.

Built on the robust ESP32-S3 platform, WiCAN Pro runs the powerful, open-source WiCAN firmware. This versatile setup supports peripheral integration such as LTE modems, GPS modules, or our upcoming ESPNetLink LTE/GPS module. These capabilities extend its utility beyond traditional diagnostics, enabling real-time location tracking and online data analysis.

Whether used in a professional automotive workshop or by hobbyists exploring the potential of car hacking, WiCAN Pro’s hardware capabilities make it a versatile tool for a wide range of applications. The inclusion of a USB-C connector for firmware flashing and a microSD card slot for data logging further enhances its functionality.

Comprehensive Protocol Support for Broad Compatibility

One of WiCAN Pro’s standout features is its support for all legislated OBD-II protocols, including:

• ISO 15765-4 CAN
• SAE J1939 CAN
• ISO 11898 raw CAN
• Single Wire CAN (GMLAN)
• SAE J1850-PWM
• ISO 14230-4

This broad compatibility ensures that WiCAN Pro can be used with a wide variety of vehicles, from everyday cars to specialized commercial vehicles. By supporting such a comprehensive range of protocols, WiCAN Pro allows users to access and interpret detailed diagnostic data, making it an indispensable tool for automotive professionals and enthusiasts alike.

Moreover, WiCAN Pro’s compatibility with various instruction sets, including ELM327, ELM329, STN, and VT instructions, ensures a versatile and user-friendly interface. Whether you’re monitoring vehicle health, diagnosing complex issues, or optimizing performance, WiCAN Pro delivers unmatched diagnostic capabilities and connectivity, redefining the standards in automotive diagnostic tools.

WiCAN Pro also supports popular OBD diagnostic apps, enhancing its versatility and user-friendliness. Compatible apps include:

• Car Scanner

Monitor, Diagnose, Repair

WiCAN Pro is a versatile, sophisticated OBD development and diagnostics tool that allows users to:

1. Integrate with home assistance systems to automate and remotely manage vehicle diagnostics and monitoring.
2. Access real-time car diagnostics data for continuous monitoring of vehicle health and performance.
3. Perform detailed inspections and troubleshoot vehicle systems, simplifying repairs.
4. Modify car functions, enhance performance, or unlock hidden features (for car hacking enthusiasts).

Seamless Integration with Home Assistant

What sets WiCAN Pro apart from other OBD2 scanners is its ability to function without an app. Unlike other OBD2 adapters that require external software to pull and process data, WiCAN Pro can be seamlessly integrated with Home Assistant and other IoT applications. This feature makes it an ideal choice for those looking to incorporate vehicle data into their smart home ecosystem, offering versatile and convenient automotive diagnostics.

Dual UARTS for Developer Flexibility

WiCAN Pro is designed with developers in mind, featuring a dual UART chip setup:

1. One UART is dedicated to flashing and debugging the ESP32-S3.
2. The other can be configured through firmware to send commands to the OBD chip.

This design provides the flexibility and control needed for custom automotive applications and development projects.
