The module can be powered by any voltage in the range 3,3V to 5V and takes about 50-70mA of current. An GPS antenna must be connected to the GPS Antenna port, you can run the module with an indoors GPS antenna that you put next to a window but for best performance use an outdoors antenna with a clear view of the sky.

A serial controllable synthesizer that will output any frequency between 33MHz to 4.4GHz. Arduino Pro Mini + ADF4351. It's a frequency generator that you control using serial commands. The synth has a built-in pre-programmed Arduino Pro Mini that runs a commands parser so you can set any frequency simply by sending is over the serial port. It can be run on voltages from 3,3V to 5V and takes about 140mA of current. There are two complimentary 50 ohms outputs that give out 0dBm. The output is pretty flat over the entire frequency range. It has a stability of 2.5ppm (parts per million) or better when using the built-in TCXO 10MHz reference.
