Hardware Guide
4.1 Typical Applications
Note: You can’t use USB to TTL 3.3V or 5V power supply, it is recommended to use two dry batteries or after conversion through the LDO 3.3V, it is strongly recommended to buy a new development board.

4.5 Antenna placement reference
The AW-01 module uses an onboard antenna or an external antenna in the 2.4G wi-fi frequency band. If the onboard antenna is used, the following figure shows two commonly used antenna placement methods that have less impact on the antenna performance. It is recommended to choose as much as possible One of the ways to place the module; Note: The second way of placement requires that the two sides of the PCB antenna are at least 5.0mm away from the two sides of the base plate
4.6 WIFI product structure design considerations
The following points should be paid attention to when placing the product board of the WIFI module in the product structure Since the metal plate and metal surface have a strong shielding effect on wireless signals, the side of the WIFI module PCB antenna must face the outside of the product in the product structure. It is forbidden to face the PCB antenna side of the WIFI module in the direction that has the shielding effect on the wireless signal, such as the PCB board and the battery;
- When installing the actual product board, the position of the WIFI module PCB antenna needs to be vertically upward;
- The WIFI module should be as far away from metal as possible in the actual product structure, such as external equipment such as transformers and motors;
- In the structural design, pay special attention to avoiding screw posts around the position of the WIFI module PCB antenna. When the screws are screwed in, it is actually equivalent to placing a metal post next to the WIFI module PCB antenna; After the actual product structure is determined, in order to achieve For the best antenna performance, it is recommended to do the antenna matching test of the whole machine.

2.4 Limited module procedures
Not applicable. The module is a Single module and complies with the requirement of FCC Part 15.212.
2.5 Trace antenna designs
Not applicable. The module has its own antenna and doesn’t need a host’s printed board microstrip trace antenna etc.
2.6 RF exposure considerations
The module must be installed in the host equipment such that at least 20cm is maintained between the antenna and users’ body; and if RF exposure statement or module layout is changed, then the host product manufacturer is required to take responsibility of the module through a change in FCC ID or new application. The FCC ID of the module cannot be used on the final product. In these circumstances, the host manufacturer will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
