Frequently Asked Questions about our Electronic Components and Modules
Are your electronic modules pre-tested for quality?
Yes, every HiLetgo component and module undergoes strict quality control protocols at the manufacturer level to ensure they meet standard electrical specifications before being listed in our inventory.
What is your policy on DOA (Dead on Arrival) items?
We offer a 30-day replacement or refund guarantee for any components that are non-functional upon arrival. Please ensure you conduct initial testing with a multimeter or breadboard before soldering, as soldered items may be ineligible for return.
Do you provide schematic diagrams or data sheets for your products?
Most of our product pages include technical specifications. For complex modules, we provide download links to data sheets and pinout diagrams. If you cannot find documentation for a specific part, our technical support team can assist you.
