FAQ
Common Q&A for electronics and DIY project buying.
How do I choose the right module for my project?
Start with input voltage, interface (I2C/SPI/UART), required accuracy, and operating environment. Share these details and we can suggest compatible options quickly.
How can I verify pinout and wiring before powering up?
Check the listing pin table, compare logic voltage (3.3V/5V), and verify common ground. For first test, use a current-limited supply and validate with a multimeter.
Do you support Arduino, ESP32, and Raspberry Pi?
Yes. Listings indicate platform compatibility and interface type. For mixed-voltage setups, use level shifting and confirm board-specific IO limits.
What if a product is out of stock?
If backorder is enabled, you can still place the order with estimated lead time. You can also request alternatives with similar specs.
Can I request pre-sales technical guidance?
Yes. Send your use case, quantity, and constraints to support and we can help shortlist parts and check compatibility.
Do you provide invoice and company purchase support?
Yes. We support business purchases and quotation workflows. Use quote request for project-based or custom quantity buying.
How do returns work for electronics modules?
Unused items in original condition are typically eligible under policy terms. Items damaged by incorrect wiring or reverse polarity are usually not returnable.
Can you help with BOM sourcing for projects?
Yes. Share your BOM, target quantity, and timeline. We can propose stocked equivalents and identify long-lead components early.
