I have the new ESC FPV 4-in-1 with Built-in Power Module (MDK-M0138) and am looking to connect it to the VOXL2 but none of the cables it comes with have the right connector (Molex, 0050375043) to go to the VOXL2 power input. 

Anyone know how to power VOXL2 from this ESC?

@restore Can you please share a picture of the ESC and the power cable that comes out of the VOXL power regulator solder pads?

@Alex-Kushleyev there was no cable coming off of the pads

@restore, which cables did the ESC come with?

@Alex-Kushleyev 
The ESC came with the 4-pin UART cable for data to the ESC but nothing for power. That's it.

@Alex-Kushleyev as Dan said there were no power cables. We received three cables : MCBL-00015-1, MCBL-00082-1, and MCBL-00091-1

@restore , sorry about that, we will email you and send the cable to you. It should have been included.

Also, just a reminder, if you are using a custom motor / propeller combination, please calibrate the ESC, otherwise RPM control may not work well. this calibration needs to be done once per motor/prop combo (for a give battery type), then you can use the same parameters on all boards that control these motors / props.

@Alex-Kushleyev Yes thank you, we will be going through all of the calibrations as our application is completely custom.
