Jetbot - No OLED, No Motors

Hello,

I’m pretty sure I failed on the soldering of all the connections on the motor controller board. The JetBot boots and I can get in to the Jupyter Notebook. Motors don’t run, OLED does not light up, no blinking lights. Other than ordering a replacement (inexpensive) motor controller board, should I try anything else? TIA.

Forgot the output of this command

jetbot@jetbot:~$ i2cdetect -y 2
