7.3. Antenna layout requirements
In the installation position on the motherboard, the following 2 methods are recommended:
Scheme 1: Place the module on the edge of the main board, and the antenna area extends out of
the edge of the main board
Scheme 2: Place the module on the edge of the motherboard, and the edge of the motherboard
hollowed out an area at the antenna position
In order to meet the performance of the on-board antenna, it is forbidden to place metal
parts around the antenna, away from high-frequency devices
Figure 12 Antenna Layout
7.4. Power supply
Recommended 3.3V voltage, peak current above 50mA
LDO is recommended for power supply; If DC-DC is used, it is recommended that the
ripple be controlled within 30mV
The DC-DC power supply circuit suggests to reserve the position of the dynamic response
capacitor, which can optimize the output ripple when the load changes greatly
It is recommended to add ESD devices to the 3.3V power interface

7.5. GPIO
Some IO ports are led out from the periphery of the module. If you need to use a resistor of
10-100 ohms in series on the IO port. This can suppress overshoot and make the level on
both sides more stable. It is helpful for both EMI and ESD
For the up and down of the special IO port, please refer to the instructions in the
specification, which will affect the startup configuration of the module
The IO port of the module is 3.3V. If the level of the IO port of the main control and the
module does not match, a level conversion circuit needs to be added
If the IO port is directly connected to the peripheral interface or terminals such as pins, it is
recommended to reserve ESD devices at the IO port wiring close to the terminals

8. Storage conditions
The product sealed in the moisture-proof bag should be stored in a non-condensing
atmosphere of <40℃/90% RH.
The moisture sensitivity level MSL of the module is level 3.
After the vacuum bag is unpacked, it must be used within 168 hours at 25±5℃/60% RH,
otherwise it needs to be baked before it can be put on line again.
