Remark
1. The development board selects the 470-510 frequency band. Be sure to read it carefully and don't make the wrong choice!
2. The antenna needs to be noted as 470 MHz . Using an antenna that is not suitable for this frequency may burn out the amplifier!
3. Antennas can be selected as needed, as long as they have an SMA male connector. If the recommended housing is used, the maximum supported antenna diameter is 12.7mm.
4. The GPS module is optional.
