LDARC AK103, Manual

-3-

  <1> STM32F411 MCU,Operation at 100Mhz,firmware target MATEKF411.
  <2> MPU-6000 six-axis SPI sensor.
  <3> Low power version AT7456E,support Betaflight OSD. 
  <4> BEC use MP9943 High-Efficiency Synchronous mode DC-DC,
          support 5V@1.5A output. 
  <5> TX1 and RX1 pads,can support IRC-Tramp or Camera control.

<6> UART2 have 4 pads, TX2, RX2, invert TX2, invert RX2, support

          all type receiver, like S.BUS, DSM, iBUS, F.Port, crossfire etc.

  <7> TX2 and RX2 pads,RX2 support NOT invert receiver,for example 
          DSM or iBUS.
  <8> Invert TX2 and invert RX2 pads,invert RX2 support invert receiver 
          like S.BUS,and PPM receiver also need connect to invert RX2 pad.
  <9> Support buzzer and LED strip.

KKT-VTX200 

parameters

        How to use the VTX: 

BULE

 LED is channel (CH) indicator,flash 1~8 

times mean CH-1~8;

GREEN

 LED is band(BD) indicator,flash 1~6 times mean 

BAND-A~F;

RED

 is output power(PW) indicator,flash 1~3 times mean 

25mW / 100mW / 200mW output power.In normal working state,quickly 

double-click button,R/G/B sync flash mean VTX turned off,and also quickly 

double-click can turn on the VTX.In normal working state,press and hold 

the key for 3s,only 

BLUE

 LED flashes,now click the key change channel(CH). 

Press and hold the key for 3s,only 

GREEN

 flashes,now click the key change 

band(BD).Press and hold the key for 3s,only 

RED

 LED flashes,now click the 

key change output power (PW).
