2 2: Power Interface
Power supply
The host device must provide power to the AirPrime soldered-down
module over pins 42 and 44 (VCC_3V6) as detailed in
Table 2-1 .
Note: The host must provide safe and continuous power to the module; the
module does NOT have protection circuits to guard against electrical
overstress.
Electrostatic discharge (ESD)
The host device must provide adequate ESD protection on digital
circuits and antenna ports as detailed in
Table 2-2 .
Note: The level of protection required depends on your application.
