Isolated Dual CAN Board (3.3V Logic | Classic CAN 2.0B) Professional-grade protection and signal integrity for your CAN bus projects.

Stop worrying about ground loops, voltage spikes, or fried microcontrollers. This Isolated Dual CAN Board is a robust communication interface designed for developers who prioritize hardware reliability and clean data transmission in demanding environments.

Key Technical Highlights:

Complete Galvanic Isolation: High-speed digital isolators physically decouple your host controller (ESP32, STM32, RP2040) from the CAN bus. This is your insurance policy against ground loops and high-voltage transients.

Superior Noise Immunity: Unlike cheap modules, this board features Industrial Common Mode Chokes on both channels, effectively suppressing EMI (electromagnetic interference) before it reaches your logic.

Ultimate Gateway Capability: With two independent, isolated channels, this board is the perfect hardware front-end for building a CAN-to-CAN bridge, CAN-to-WiFi/Bluetooth gateway, or an industrial data logger.

Precision Signal Integrity: Features high-precision, symmetrical 120Ω termination resistors, selectable via onboard SMD DIP-switches. No soldering, no messy jumpers—just flick a switch to stabilize your bus

Technical Specifications: Standard: Classic CAN 2.0B (Non-FD).

Logic Level: 3.3V (Compatible with ESP32 series, STM32, RP2040, Teensy, etc.).

Dimensions: 56 x 75 mm (Features M3 mounting holes for easy integration).

Interface: Standard IDC 10-pin header (ribbon cable included).

Connectors: Industrial-quality pluggable screw terminals for CANH, CANL, and GND.

Shipping & Sustainability 📦 Shipping from: Munich, Germany. 🌍 Eco-Friendly Packaging: To reduce environmental impact, I prioritize the use of recycled or previously used cardboard boxes. Your hardware will be packed securely and professionally, even if the outer box has a "previous life." Thank you for supporting sustainable engineering! ⚡ Tested & Ready: Every unit undergoes a 100% functional test before being dispatched.
