RDM6300 125KHz (ID) RFID reader module (HCRFID0006)
RDM6300 125KHz card reader mini-module (HCRFID0006) is designed for reading code from 125KHz (ID) compatible read-only tags and read/write cards. It can be applied in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc. The reader will output id code of any compatible tag placed with within range via its serial UART interface. The reader requires no software interaction and can be interfaced directly to a microcontroller or to a PC via a serial port interface such as a USB to serial adaptor (also available via our website).Specification:
Support external antenna
Maximum effective distance up to 150mm*
Less than 100ms decoding time
Uart interface (9600 Baud)
Support EM4100 compatible read only or read/write tags (125KHz ID)
Small outline design
*Please note range is also dependant on sensitivity of tags used. Approximate range when used with HCRFID0005 and HCRFID0009 passive tags is between 2 ~ 4cmPinout:FAQ:Could you clarify power to the board, is that 5v on (P1, pin 5) or (P3, pin 2) ?
Either 5V power pin will do, they are connected together.What is the LED pin for ?
It allows an LED to be connected to act as an indicator. There is a 100 ohm pullup resistor connected from 5V to this pin. The pin is momentarily pulled low whenever a card or tag is in range. You can connect the anode (+ve) of an LED to this pin and the cathode (-ve) to the GND pin. The LED will be illuminated when no tag is in range and will continuously blink when a tag is in range. However we've found to be quite short (about 1ms) so its only just visible. If you are using it with a microcontroller we'd recommend using it to control an LED instead.
