Nano CAN Bus Sniffer Kit with Arduino Nano + LED
Nano CAN Bus Sniffer Kit with Arduino Nano + LED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your Arduino Nano into a portable CAN bus sniffer that captures every frame on the network. This kit guides you through building a self-contained diagnostic tool with an onboard OLED display and microSD logging — perfect for automotive hackers, engineering students, and anyone diving into modern vehicle electronics.
What You'll Build
A fully functional CAN bus sniffer that plugs into any OBD-II port and reads CAN frames in real time. The 0.96-inch OLED screen scrolls message IDs and data bytes, while the microSD module records each frame with a precise timestamp from the DS3231 real-time clock. You'll leave with a field-ready device you can use to decode vehicle messages or debug industrial CAN networks.
What You'll Learn
- Wiring and interfacing the MCP2515 CAN controller with Arduino Nano using SPI
- Capturing and parsing CAN 2.0B frames at up to 1 Mbps
- Logging timestamped data to a microSD card with a DS3231 RTC
- Displaying real-time CAN IDs and data on an I2C OLED screen

Who This Kit Is For
This kit is built for B.Tech ECE and EEE students working on automotive electronics projects, CBSE Class 12 students exploring communication protocols for board exams, and hobbyists participating in Smart India Hackathon or building their first CAN bus diagnostic tool. If you've ever wondered what your car's ECU is saying, this kit demystifies it without guesswork.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with the AI build companion, trained on this exact project. If you need human help, WhatsApp support is also available.
Does this kit work with all cars?
The OBD-II connector fits standard J1962 ports found on all cars sold in India after 2013. For older or heavy-duty vehicles, pinout details are provided in the guide.
Is soldering required?
Yes, you'll solder components onto two prototype boards. The kit includes a soldering iron, solder wire, and detailed PCB layout diagrams to help you succeed.
Can I use the sniffer without an SD card?
Yes, the OLED display shows live CAN frames even with no card inserted, allowing you to inspect IDs and data on the fly.
MCP2515 on Nano captures all CAN frames. Tiny OLED shows ID and data. Logs to SD with timestamps.
