Features: Support parameter adjusted by Betaflight,fligth controller,OSD 25mW/200mW/600mW and Turn-off (PITMODE) switchable 5V BEC output, support power for receiver and camera 0% inteference when power on and swtich channel, definitely won& 39;t intefere others With overheating auto protective design, to prevent damge With protective function that will not damage when forget to connect the antenna. Support OSD configuring channel, power level and PITMODE mode switch Support PMW channel switch and PITMODE switch It can save the power setting It can lead out buttons to adjust the parameter out of the module Mini Nixie tube displayer Descriptions: Working Voltage : DC6-24V Working Current : 130mA(25mW)/230mA(200mW)/280mA(600mW)/12V Working Frequency : 5.8G Working Channel : 48CH Transmit Power : 25mW/200mW/600mW/Turn OFF adjustable Transmit Distance : 200m(25mW)/1.5km(200mW)/5km(600mW), in open area with 4-leaf clover antenna Interface : 1*RP-SMA ANT Connector 1*7P Socket (Video-in,GND,PMW-IN,Audio-in,5V-out,GND,Video-in) 1*Displayer 2*Button Specifications: Color:black Size:40*22.6*7.25mm/1.57*0.89*0.29inch Adjustable 4 models:25mW/200mW/600mW/off Package Included 1 *FPV Transmitter 1 *Aerial 1 *Cable Note : Had better connect the antenna before you power on it, can pretect the module. 2. 5V voltage input, the max current is 1A. Operation : Power Switch *Power on, power setting is same as last time you used. *Long press Power Button, switch among 25mW,200mW and 600mW circularly *Short press Power Button twice, turn on or turn off transmitting. "TX" indicator on is tranmitting, off is turon off(regardless of the other 2 LED) *25mW works : "TX"on; 200mW works : "TX""200mW" 2 indicators on; 600mW works : 3 indicators all on Channel Switch : *Long press Channel Botton, switch among A-B-C-D-E-F circularly, short press to switch CH1-CH8 circularly *When connect PMW, there is signal in 3 seconds, the decimal point on displayer is lighting, you can use the remote control transmitter to configure 1-8 channels and turn off the transmitter; Otherwise, it will enter the button configuring mode aftger 3 seconds, the decimal points won& 39;t show up. *Can lead out the configuring button for setting, there is bonding pad for button on module.
