Product Usage Instructions
Chapter 1: Product Overview
The ZFB0-BT01CL is a BLE 5.4 Slave Bluetooth UART Transparent
Module developed by Ningbo Youwon. It enables communication with
various serial port devices using specified communication
protocols.
The module operates as a slave device by default. A master
device (e.g., smartphone, host module) can actively establish a
connection with it after scanning, requiring no user intervention
during the pairing process. Once connected, users can treat it as a
standard serial port device to transmit data directly to the
module.

Chapter 7. Module Basic Circuitry and Common Issues
7.1 The basic application circuit is shown in Figure 7-1.
Figure 7-1
7.2 Common Issues 1. At room temperature, if the power supply voltage is lower than the
recommended value, the transmission power will decrease as the voltage drops. 2. If there are metal objects near the antenna or if it is placed inside a metal
enclosure, signal attenuation will be severe. 3. When there are obstacles in the direct line of communication, the
communication distance will be reduced accordingly. 4. Temperature, humidity, and co-channel interference can lead to an increase
in packet loss rate during communication. 5. Radio waves are absorbed and reflected by the ground, resulting in poorer
test performance when testing close to the ground.
14
Ningbo Youwon Technology Electronics Co., Ltd.
ZFB0-BT01CL UserManual
6. Seawater has a strong ability to absorb radio waves, leading to poor test performance near the seashore.
7. Errors in setting the power register or an excessively high air data rate (the higher the air data rate, the shorter the communication distance) can also cause issues

Chapter 8. Precautions
8.1 Precautions 1Power Supply Selection The positive and negative poles of the power supply must be correctly connected. Reverse connection may cause permanent damage to the module. It is recommended to use a DC regulated power supply for powering the module, with minimal power supply ripple factor. The module must be reliably grounded, and the power supply voltage should be maintained within the recommended range without significant or frequent fluctuations. Exceeding the maximum voltage value may cause permanent damage to the module. 2Precautions for Secondary Development During secondary development, attention should be paid to the routing method. For example, high-frequency digital routing, high-frequency analog routing, and power supply routing must avoid passing beneath the module. If it is necessary to pass beneath the module, the part of the module soldered on the Top Layer in contact should be covered with ground copper (fully covered with copper and properly grounded), and the digital part near the module should be routed on the Bottom Layer. If the module is soldered or placed on the Top Layer, it is incorrect to route randomly on the Bottom Layer or other layers, as this will affect the module’s stray parameters and receive sensitivity to varying degrees. Furthermore, routing with significant electromagnetic interference (such as high-frequency digital, high-frequency analog, and power supply routing) around the module can greatly affect the module’s performance. Depending on the intensity of the interference, it is recommended to keep an appropriate distance from the module or, if possible, implement appropriate isolation and shielding.
