Overview

Wiring Connections

TX (Transmitter):
- Connect to the RX (Receive) pin of your microcontroller or UART interface.
RX (Receiver):
- Connect to the TX (Transmit) pin of your microcontroller or UART interface.
VCC (Power):
- Connect to a 5V or 3.3V power supply depending on the module specifications.
GND (Ground):
- Connect to the ground of your power supply or microcontroller.

Power

Operating Voltage: 5V or 3.3V (check the module specifications for exact requirements)
Current Consumption: Typically low, around 50 mA during operation

Input and Output

Input: RFID card placed within the reader’s range.
Output: Serial data stream corresponding to the RFID card’s unique identifier (UID). The UID is transmitted via the UART interface.

Physical Characteristics

Dimensions: Compact and small, often around 40 mm x 30 mm (1.6 inches x 1.2 inches)
Weight: Light and easy to handle
Housing: Usually enclosed in a plastic or metal case for durability and protection

Technical Specifications

Frequency: 125 kHz (EM4100 standard)
Serial Communication: UART with standard settings (9600 baud rate, 8 data bits, 1 stop bit, no parity)
Data Format: Sends the UID of the RFID card as a series of bytes
Response Time: Typically fast, with data readout in milliseconds

Additional Features

LED Indicator: Some models include an LED to indicate card detection or read status.
Mounting Holes: Often equipped with holes for easy mounting on various surfaces.
Integration Support: Compatible with popular microcontrollers like Arduino, ESP32, and Raspberry Pi.

How to Use

Connections:

- Power: Connect the VCC and GND pins to your power supply.
- Serial Communication: Connect TX and RX pins to the corresponding UART pins on your microcontroller or serial interface.

Setup:

- Power On: Ensure that the reader is powered correctly.
- Serial Configuration: Configure your microcontroller or serial interface to match the UART settings of the RFID reader (usually 9600 baud rate).

Reading Cards:

- Card Placement: Place an EM4100 RFID card within the effective range of the reader.
- Data Reception: The reader will transmit the card’s UID via the UART interface.
- Data Handling: Read the UID data on your microcontroller or computer and process it according to your application needs.

Integration:

- Programming: Write code to handle the incoming data from the reader. For example, use Arduino code to read and process the UID.
- Application: Use the UID for access control, identification, or other applications where RFID cards are used.

Maintenance:

- Check Connections: Regularly ensure that all connections are secure and correctly configured.
- Test Functionality: Periodically test the reader to ensure it is accurately reading RFID cards.

Troubleshooting:

- No Response: Verify power supply and connections.
- Incorrect Data: Check UART settings and ensure the card is within range.

The UART EM4100 RFID Card Reader RDM6300 is a versatile and reliable module for reading RFID cards. Its UART interface allows easy integration with various electronics projects, making it suitable for applications such as access control and identification systems.
