2.2 Suggestions for using module PCB
⚫ It is recommended to use LDO to supply 3.3V DC and provide the driving capacity of at least 80mA
peak current. It is recommended to place a 10uF capacitor at the module power inlet.
⚫ In PCB layout planning, BLE modules should be placed away from magnetic field sources such as
transformers and coils.
⚫ Antenna areas should be kept PCB design clear and not protected by any enclosure. Antennas must
be at least 10mm away from metal or tall components.
⚫ If there are other special requirements, the module can be customized.
