    I killed both of my 22HV with 8V. It’s rated up to 8.5V. I belive its to weak. The first one worked for a week, the second one died on the bench.

    210DMH 3.9kg/cm (stock)
    vs
    22HV 2.5kg/cm

    21HV 3.2 kg/cm
    20HV 4.3 kg/cm

    The next one i try is the 20HV. Bit more torque than stock. It should be also faster with load.

    Really? I thought i did it once. Maybe is was betaflight or inav.

    Then flash betaflight 3.0 the your board, do the passthrough. And flash back triflight.

    Yes its possible. No FTDI is needed.

    First connect with cleanflight app go to cli an type:

    passthrough 2 56700
    Com1 = 0
    com2 = 1
    com3 = 2
    ….

    Disconnect cleanflight app and open MW_OSD_GUI. Then connect to the same serial port. the passthrough is active until you power off the flight controller.

    It depends how the R8 restistor on you board is set. Is it set to BEC it should take up to 3 Amps without problems.
    Is it set to 5V then only 200mA can be drawn and you killed the LDO.

    F3FC Tricopter Frame (with integrated Power distribution)

    Instructions on how to select UART1 voltage and UART2,3 and PWM voltages:
    R8, which have the marking 5V/BEC sets the voltage output on UART2,3 and PWM5+6. If BEC is selected (which is the default) The voltage will be whatever the built in BEC voltage is set to (5V default) If a higher BEC voltage is selected (for instance 8V) the 0 ohm resistor can be moved to the 5V position. This will engage a small LDO voltage regulator that will supply the UART2,3+PWM5,6 with 5V power. The current rating on this regulator is rather small (around 200mA) so it’s extremely important that you don’t try and power LED’s through any of the PWM ports while using this option. This option is available so that sensitive UART devices that cannot operate on 6 or 8V can still be powered through the board without an external power source.

    Telemetry setting has to be S.Port or Smart Port. On one Uart 2 or 3 . (img 6)

    Frsky is the older Telemetry type of Frsky. The XSR like the X4R, X6R and X8R only knows s.Port.

    And then TX and RX (of the UART you choose 2 or 3) have to be connected both to the one s.Port Telemetry wire. (img 4)

    And i suggest updating the Taranis to 2.1.18 telemery is handled a bit different (better).

    Soldering looks good.
    When i connect both pin with a wire it enters bootmode but it won’t be recognized by cleanflight.

    The board has two problems. One is the button, i don’t care.
    But it wont be recognized as dfu.

    Without Battery connected it shows always strange things, depends on the flight controller and current sensor. On some quads i have -24Amps, thats ok.

    Important is whats shown with flight battery connected.

    “Cleanflight say current draw is 0.36 A then only Battery and FatShark VTX (not OSD) connected.”
    That sounds right…

    MinimOSD needs about 500mA, if it is powered via usb port (I don’t know if the F3FC board does that) there might be a problem. But it should not make problems when flying.

    what is showing in Cleanflight (with flight battery) when all is connected and
    1.) disarmed?
    2.) Cleanflight armend?
    3.) MWOsd armed?

    Remove your props when doing that.

    I tried it on a fresh computer (my wife’s laptop) where no zadic and no lots of different driver are installed.
    Didn’t worked either.

    Does the comport appear in cleanflight?

    Is something else connected to the serial 1? like osd or gps.

    What is the yaw tab? Never seen.

    Spinning like crazy:

    You did the servo reverse because when pushed yaw on the transmitter to the left. The servo went to the left (right turn for the tricopter)? When the tri startet yawing to the left the board tried to stop and made more left rotation because of servo reverse.

    What if your transmitter is reversed?

    With the new board pick up the tricopter. Leave it armed. And totate by hand. Only then you see if the servo is making the right moves.

    Spinning like crazy = servo direction wrong in FC
    Left/Right wrong in Hover = transmitter yaw reversed

    Ist your computer detecting to usb port?

    Ofcause Airmode was on… (I reviewed the Taranis log file) The quad was perfect balanced when it tried to kill me. 🙂

    Next time doingt repairs i let the Gopro run. 🙂

    to repair your board you can do this. cut the signal line from the minus pad (red X) with a sharp knive ( be carful). And use the minus from the other side.

    Then take some very small wire and solder it the the signal wire (blue) scrap of the coating until you see the cooper.

    Then hotglue or epoxy the wire (blue) to the board. so that nothing rips it off.

    I killed lots of boards and ESCs that way.

    in reply to: Are resistors needed for the servo feedback? #30081

    I’m running a ACS758 (100A) current sensor on the ADC with 5V supply. Most of the time I’m in the range 0-3.3V but it can go up to 5.0V at 100 amps current. Never damaged something. First board is still working.

    But im using a RC filter with a resistor about 500k so there is not much current on the signal pin.
    The maximum reading i get is something about 67Amps that 3.3v on the adc.

    To be on the safe side you could put a 1k resistor in series for current limiting it will protect the adc pin.

    I don’t know exactly but i thought the servo feedback never reaches more that 3.3v at 40 deg.

    Stm32 does have two type of pins:
    5V tolerant: VCC+4.0V = 7.3V
    non-tolerant: VCC+0.4V = 3.7V

    I can’t find it in the manual what a adc pin is.
