Thank you for the clue. Upon closer inspection I noticed that the solder joint on the M2 wire closest to FET#2 (Q2's Drain) had pushed through and lifted the solder pad :-( During our initial tests, the resistance check across all the motors worked because I was testing directly at wire connections....

Hi again, So here is my update after following your suggestion: - I attached the props and plugged in the battery - I did not attach the USB cable to the micro USB port - The LEDs flashed in the correct sequence Outcome: - Three of the four motors rotated correctly (M1 and M3 in CCW direction and M4...

First, thank you so much for the prompt response!
I have not done these steps yet. I was worried when the boot-up did not show all the expected behavior so I did not proceed any further. I will do these tests later this evening and post back. Thanks again.

Hi all, I soldered the four motors and did a resistance check across each of them to confirm 2Ohms. (NOTE: The reading stabilizes to 2 ohms after about 3 or 4 seconds). Everything seems to be fine so far. When I plug it into a PC, the green LED quickly flashes 5 times and the red led blinks after th...
