Output Voltage: Two output voltages, It can supply power to 5V and wide voltage cameras, Select the output voltage through a three-point jumper pad, and check the wiring scheme drawing for operation details. 1.The jumper pad is short circuited to the two points on the right, and the output is 5V at this time. 2.The jumper pad is short circuited to the left two points, and the input voltage of the power supply is output at this time. Three schemes of actual wiring diagram: Wiring scheme 1: It is suitable for Mini camera with voltage of 3.3-5v and current less than 100mA. If there is no condition to verify that the camera meets the above voltage and current conditions, this wiring is prohibited, otherwise there is a great risk of damaging the transmitter. Due to different batches, there may be differences in the appearance, color, and printing of the product, which will not affect its use. Transmission Characteristics: Output Power: 2000mW Operating Voltage: 8V-25V(2S-6S) Operating Current: 800mA(12V testing) Channel : 24CH Video Format: NTSC/PAL Output Voltage: 5V/Input Voltage(Jumper cap selection) Antenna Interface: SMA(External thread internal pin) Material: plastic+metal colour: Black Package Contents: 1 x Transmitter Kit 1 x 1200TVL 2.5mm CMOS Wide Angle PAL FPV Camera 1 x for FPV USV OTG 5.8G UVC Receiver(Random color and appearance, Cannot be chosen the specific color and appearance) 1 x Type-C OTG cable 1 x Micro-USB OTG cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
