Requires Careful Wiring

Works as advertised but the pinout diagram was slightly confusing. Make sure to check voltage jumpers before powering.

Good Value but Manual is Thin

Hardware is solid and communication is stable. I wish the documentation had more examples for A/D sensor integration.

Perfect for STM32 Projects

Integrated this into my automotive data logger and it worked immediately. The TTL levels match perfectly with my Blue Pill board.

5 FAQ

Q: What library works best for STM32?

Q: Can it handle standard OBDII protocols?

A: Yes, it supports standard CAN 2.0B frames used in OBDII systems.

Q: Is optical isolation included?

A: No, this model is non-isolated. Please check our isolated version for high voltage protection.

Q: How does the A/D conversion interface work?

A: This module transmits data from external A/D sensors over CAN. It does not perform conversion itself.

Q: Does this support 3.3V logic?

A: Yes, there is a jumper to select between 3.3V and 5V logic levels.
