Arduino Nano 33 BLE Sense system

I need to create designs around the Arduino nano 33 ble sense. Anyone can help be start (I just downloaded the program with a donation)

The first thing to do would be to use the corrected Fritzng part in this post as the original on the Arduino site is broken.

After that if you upload the sketch (the .fzz file, upload is the 7th icon from the left) that illustrates the problem you are having someone here will likely help.
