pay attention:
1. The input voltage should not be too high to avoid damage to the module
2. The read 10-digit hexadecimal number is not the card number, the card number is the number after converting the last 6 digits of the read-out number from hexadecimal to decimal.
1. This product is a 125KHz RFID card decoding module, and the antenna is integrated in the PCB.
2. The interface adopts 5PIN interface, which are VCC, J1, Tx, J2, and GND. At the same time, Schottky diodes are added to the power supply for anti-reverse connection protection.
3. This module is suitable for most low-frequency ID cards.
4. The module has 3 output modes: UART output, IO direct output, and transistor open-drain output. The module adopts three kinds of interface output:
1. Pin Tx uses UART to output data, the output data format is 10 ASCII codes + 1 space, and the card number is 10 data (see Figure 1). The baud rate is set to receive data in the way of sampling figure 1.
2. If the product does not need to
