Frequently Asked Questions

Q: Are these boards and modules compatible with Arduino projects?

A: Yes! Many of our boards and modules, including our TFT LCD displays and SPI-based modules, are fully compatible with Arduino microcontrollers and other popular development platforms. Product listings include pinout and wiring details to help you get started quickly.

Q: What is the difference between NFC NTAG213 sticker tags and IC smart cards?

A: NFC NTAG213 sticker tags are thin, adhesive labels ideal for embedding into objects, packaging, or surfaces for asset tracking and automation. IC smart cards, such as our 13.56MHz cards for Tuya hotel door locks, are rigid cards designed for access control and authentication systems. Both operate at 13.56MHz but serve different form-factor needs.

Q: What should I look for when choosing a brushless motor for my FPV drone?

A: Key specs to consider include KV rating (RPM per volt), stator size, and compatible battery voltage (e.g., 1S or 2S LiPo). Our 1104 4300KV brushless motor is optimized for mini and micro FPV quadcopters running on 1-2S batteries, offering an excellent power-to-weight ratio for racing and freestyle flying.

Q: Do the lithium battery PCB protection boards work with all 18V tool batteries?

A: Our 18V Li-ion PCB protection boards are specifically designed for BL1850B and BL1840B battery configurations. Always verify cell count, discharge rating, and connector compatibility with your specific battery pack before installation to ensure safe and reliable operation.
