Reliable communication bridge
I used this to connect a legacy sensor array to a modern microcontroller. The TTL conversion is clean with no noticeable latency. Highly recommended for robotics applications.

Great value, minor documentation gaps
The hardware quality is excellent for the price. Transmission speeds are stable up to 500kbps. I wish the pinout diagram in the manual was slightly clearer, but online resources filled the gap.

Excellent noise immunity
The isolation feature really shines in electrically noisy environments. Data integrity remains perfect even near large motors. A solid choice for professional sensor accessories.

Good starter module
As someone new to CAN bus systems, this module made learning easy. It pairs well with Arduino and STM32 Nucleo boards. Just ensure your voltage levels match before powering up.

Perfect for industrial prototyping
This module worked flawlessly with my STM32 project. The optical isolation gives me peace of mind when connecting to heavy machinery controllers. Setup was straightforward using standard libraries.

Robust build quality
We deployed ten of these in our testing rig. They have been running 24/7 for three months without a single dropout. The high-performance claim holds true under load.
Q: What is the maximum cable length supported?
A: Cable length depends on the baud rate. At 1Mbps, we recommend up to 40 meters. At lower speeds like 50kbps, you can extend up to 500 meters with proper shielding.
Q: Can I power this directly from a 5V USB source?
A: Yes, the module accepts a 5V input via the pin header. However, ensure your USB source can provide at least 100mA for stable operation under load.
Q: Is the source code for the STM32 firmware open?
A: The hardware is fully documented, but the internal bootloader firmware is proprietary. You do not need to modify it; you interact with the module via standard UART commands.
Q: Does it come with a DB9 connector attached?
A: The module includes a soldered DB9 female connector on the board, as well as unpopulated pin headers for custom wiring options.
Q: Does this module support CAN FD protocol?
A: No, this specific model supports the classic CAN 2.0A and 2.0B protocols. For CAN FD requirements, please check our newer XL series modules.
