-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.

if use 2S battery please make sure voltage not lower than 6.8V
when ESC in heavy load.
LDA-F411E12A parameters
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).
