4.2 Antenna VC4SMN512 default connection board PCB antenna, Users can also choose to connect an external antenna via zero ohm resistor. In order to guarantee the transmission performance, it can not exist around the module ground plane.When using an extenna antenna,you need to pay attention to the antenna lead-out portion of the motherboard design..Ensure the transmission line impedance matching.

6 Module Size Figure6.1 VC4SMN512 Size（mm） 7 FCC Cautions Lbelling requirements This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
pliance. such modifications could void the user's authority to operate the equipment. the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed IMPORTANT NOTE: In the event that these conditions cannot be met (for example co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product.
