Shanghai Yancan Electronic Technology Co.,Ltd. 4. Application and Layout 4.1 Application Block Diagram Figure 3. Application Block Diagram 4.2Layout Guideline 1. The antenna needs to have enough clearance area. 2. The filter capacitor should be as close as possible to the module. 3. Do not place strong interference lines under the module. Note: When using PUART, UART_CTS signal must be pulled down to the ground.
