❓ Frequently Asked Questions (FAQs)
1. What is the range of the RDM6300 RFID reader module?
The RDM6300 typically has a read range of 20mm to 50mm, depending on the quality and size of your 125KHz RFID card or keychain tag.
2. Can I use RDM6300 to write data to an RFID card?
No, the RDM6300 is a read-only module designed to read the unique ID code from 125KHz EM4100 tags. If you need a read-write module, you may need to look at other options like the RC522 (13.56MHz).
3. How do I connect the RDM6300 to an Arduino Uno?
Connect the VCC to Arduino 5V, GND to GND, and the TX pin of the RDM6300 module to a SoftwareSerial RX pin (e.g., Pin 2) on the Arduino. No complicated hardware setup is needed; standard serial communication is sufficient.
4. Where can I buy the original RDM6300 RFID reader in Bangladesh?
You can buy the genuine RDM6300 RFID Reader Module with the best price directly from HTE Bangladesh (www.htebd.com) with shipping options available across the country.
