Main Color:Green(As The Picture Shows)
Relations Working voltage (volts) and supply current (mA) and transmit power (dBm) is as follows:
9V, 24mA, 10.2dBm (that is, 11 mW)
8V, 21 mA, 9.5dBm
7V, 19mA, 8.5dBm
6V, 17mA, 7.1dBm
5V, 14mA, 6.1dBm (about 5 mW)
4V, 12mA, 4.5dBm
3V, 9mA, 2.2dBm
2V, 6mA, -1dBm (about 1 milliwatt)
1.5V, 4.2mA, -4dBm (about 0.5 mW, the average family environment launch sufficient, small green radiation!)
1V, 2.4mA, -9dBm
0.7V, 0.9mA, -20dBm (that is 0.01 mW)
