Design Guidance 7.1. Module application circuit 200mA,suggest use DC-DC or LDO independent power supply)
Figure 10 Application circuit diagram Note Because THERE is no reset pin for TG-02F, we realize the reset by cutting off power. A triode and PMOS can be used at the power input end to realize the reset of the module. 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 extends out the edge of the motherboard. Scheme 2:Put the module on the edge of the motherboard,and empty an area along the antenna position. To meet the performance of the on-board antenna,metal parts are not placed around the antenna,away from the high-frequency device. Copyright 2022 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 15 of 21 TG-02F Specification V1.0.0 Figure 11 Antenna layout diagram 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. 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. Figure 12 Dc-dc step-down circuit diagram Copyright 2022 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 16 of 21 TG-02F Specification V1.0.0 7.4. GPIO Some IO ports are introduced outside the module. If necessary, it is recommended to use a resistor of 10-100 ohms in series on the IO ports. This inhibits overshoot and makes both sides level more stable. It is helpful for EMI and ESD. For special I/O ports to be pulled up and down, refer to the usage instructions in the specifications, which may affect the module startup configuration. The IO port of the module is 3.3V. If the IO level of the main control and the module do not match, a level conversion circuit needs to be added. If the I/O port is directly connected to a peripheral port or terminals, for example, a pin row, reserve an ESD device near the terminal of the I/O cable.
