Design guidance 7.1. Module application circuit
(>=200mA,suggest use DC-DC or LDO independent power supply) Figure 10 Application circuit diagram Note:
Because the PB-03M does not have the reset pin,we can achieve the reduction by power off,we can restore the module with a PMOS to achieve the reduction of power off. TX&RX serial port line,2 resistors are reserved,in series in the line.The 3.3V voltage used to prevent the serial port affects the reset of the module. Copyright 2021 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 15 of 25 PB-03F Specification V1.0.0 7.2. Antenna layout requirements The installation position on the motherboard suggests the following 2 ways:
Scheme 1:Put the module on the edge of the motherboard,and the antenna area out of the motherboard edge position. Scheme 2:Put the module on the edge of the motherboard,and empty an area along the antenna To meet the performance of the on-board antenna,metal parts are not placed around the antenna,away from the high-frequency device Figure 11 Schematic diagram of the antenna layout 7.3. Power supply Recommended 3.3V voltage,peak current over 200mA. Power supply is recommend to use LDO;If the DC-DC is used,the ripple is recommended to be controlled within 30mV The DC-DC power supply circuit proposes to reserve the dynamic response capacitance to optimize the output ripple with large load changes. 3.3V power interface it is recommended to add ESD devices.

GPIO Some IO ports are lead outside the module,if using,a proposed resistance of 10-100 ohms on the IO port.This suppresses the overshoot and enables smoother levels on both sides,helping for both EMI and ESD. The up and down of the special IO port should refer to the use instructions of the specification,which will affect the start-up configuration of the module. The IO port of the module is 3.3V,if the main control does not match the IO port level of the module,the level conversion circuit should be increased. If the IO port is directly connected to the peripheral interface,or terminals such as pin header,it is recommended to reserve ESD devices at the IO port line near the terminal.
