Hello,

I have loaded the sketch "bldc_shield_blinky_test" and it looks like the shield cannot be found. I have tried two different Arduino Unos as well with the same result.

When I open the serial monitor I get:

INFO: Starting initialization
INFO: Sending reset request to all boards
WARNING: Board[1]; Command[901]; Answer[0]
WARNING: Board[1]; Command[901]; Answer[0]
WARNING: Board[1]; Command[901]; Answer[0]

Here is a pic of the unit. LED2 lights up white when 12VDC is supplied to the shield.

Can anyone provide me with some next steps or troubleshooting?

FWIW, I had the same problem when trying an Adafruit ESP32-S2 Metro Express, but it pretty much "just worked" with an old Arduino UNO I had lying around. Would really like to use something newer...than an UNO. Don't have a theory for root cause.
