Reference Design
Typical application design
As shown in the preceding figure, PIN17 and PIN16 are UART interfaces and need to be connected to the customer’s MCU. The user can reset the module through the RESET. PIN9 is the AUX pin, which is used to output the state of the module, the customer can choose to connect the LED to show whether the current module is busy. If you need the library files of schematic diagram and PCB diagram, please contact the technical support of ManThink.
Antenna wiring
As shown in the preceding figure, the antenna design can refer to the preceding figure.
The detailed rules are as follows:
- Cr2,Lr1 and Cr1 form a π-type impedance matching network, which can select vertical and horizontal topologies. Its purpose is to reserve parameter values for fine tuning capacitance and inductance, by default, Lr1 is welded with a resistance of 0Ω, while Cr1 and Cr2 are not welded.
- Two-layer PCB, FR4 material, 1 ounce copper thickness, suggested theoretical line width is 20mil
- In addition, it should be noted that the impedance matching of the interface is 50Ω.
