The application of information

The input power

It is recommended to filter the VCC port with a capacitance of 100~470uF to reduce the traction t o the power supply caused by the quick opening and closing of the power amplifier during RF tran smission. 0.1uF/100pF capacitors filter out power supply ripple in different frequency bands. Since the current is high when the module is working at full power, the module may not work sta bly when the battery is low when the handheld device is powered directly by the battery, so it is r ecommended to boost the VCC to 5V.

Enable or reset
is enabled, with built-in pull-up resistance (100k) to VCC. When the module is powered on at h igh level or suspended, the module will be powered off when it is connected to low level (low level should be less than 0.4V, high level should be greater than 0.9V and less than VCC). Rst reset, built-in pull-up resistance to 3.3V, reset when connected to low level.
GPIO interface

Input:

Logic low ＜ 0.8V minimum 0V
Logic high ＞ 2 V Maximum 3.3 V

Output:

Logic Low maximum 0.4V
Logic High has a minimum of 2.9V and a maximum of 3.3V The maximum output current of the I/o port is 5mA.

The antenna connection

The output impedance of the antenna port is 50 ohms, and the antenna standing wave ratio is rec ommended to be less than 1.5. A better antenna standing wave ratio can get better card reading effect.

The communication interface (RDX/txt)

The communication interfaces RXD and TXD are at TTL level, and the default baud rate is 115200b ps

However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
This device may not cause harmful interference, and this device must accept any interference received, including interference that may cause undesired operation.

FCC Caution:
