FAQ
What's the catch at this price?
Documentation and QC are community-grade rather than industrial. Buy one, read the CAN protocol doc, run it for a week — then order the fleet. That single test predicts project success better than any torque number.
Counterfeit risk?
Popular budget modules attract marketplace clones. Buy from the maker's authorized channel and verify serials, especially on multi-unit orders.
