Supply voltage

5V DC from USB or 6-position JST-GH (100mW)
7~35V DC form 4-position JST-GH (500mW or 1000mW)

Transmit current

300 mA/5V at 20dBm
500mA/7V at 27dBm 800 mA/7V at 30dBm

Receive current

40 mA Serial interface: 3.3 V UART

Please note: when 500MW or 1000MW output is taken, battery must be used for power supply, otherwise the transmission will be unstable.
