4. Precautions 4.1 Power supply Power supply, try to use a clean power supply, the ripple is controlled within 30mV； 4.2 Antenna 4.3 The module can choose the on-board antenna or the external wire antenna. When laying the patch, the antenna should be completely clear, and no copper or wiring should be placed； 4.4 The side with IC on the module should not face the high-frequency components on the driver, but should face the outside of the driver board； 4.
4.7 For the module with the antenna welded, there are front welding and back welding methods. If you find that the module with the antenna welded on the front is not easy to place, you can consider using the module with the antenna welded on the back. 6/6 © Granwin IOT Technology (Guangzhou) Co.
