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 use UART to read the specific card number, it can directly read whether the card is swiped successfully through the IO port of J2.
Successful card swiping will be accompanied by UART data output. During data output, J2 port maintains high level. When the data output is completed or in the idle state, it always outputs low level.

3. The J1 port and the J2 port have an opposite level, but this port is an open-drain output, and the corresponding level can be output through a pull-up resistor. It can also be connected to 12V load and 24V load.
The port design is for subsequent product upgrades, driving relays, etc. The sink current of the port cannot exceed 100mA. (If the customer needs to directly drive the relay, the corresponding program needs to be replaced).
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
