  • Working voltage: Ultra wide 0.7V to 9V
  • Frequency adjustment range: Wider than 88-108MHz
  • Launching distance: Open space 50-100m  (When working at 9V, use 70cm wire for antenna)
  • The relationship between operating voltage (volts) and supply current (mA) and transmit power (dBm) is as follows:
    • 9V, 24mA, 10.2dBm (that is, 11mW)
    • 8V, 21mA, 9.5dBm
    • 7V, 19mA, 8.5dBm
    • 6V, 17mA, 7.1dBm
    • 5V, 14mA, 6.1dBm (about 5mW)
    • 4V, 12mA, 4.5dBm
    • 3V, 9mA, 2.2dBm
    • 2V, 6mA, -1dBm (about 1mW)
    • 1.5V, 4.2mA, -4dBm (about 0.5mW, the general home environment launch is enough, the green radiation is small!)
    • 1V, 2.4mA, -9dBm
    • 0.7V, 0.9mA, -20dBm (ie 0.01mW)
  • Wiring method: The back of the core board is marked with +, -, and ANT, which represent the positive pole, negative pole and antenna end of the power supply. The antenna is usually soldered with a short wire of 0.7 meters long. It is very easy!
