Wired Connections

The QT Py RP2040 is powered by a 5V 1A USB power supply.

• The AW9523 connects to the QT Py using Stemma QT cable.
• The 4x red LED noodles connect to pins 15-12 on the AW9523.
• The 4x green LED noodles connect to pins 7-5 on the AW9523. 
• 220ohm resistors are inline with the ground (cathode) of the green LED noodles.
