Adafruit RP2040 Prop-Maker Feather board

 The Adafruit RP2040 Prop-Maker Feather combines the RP2040 processor with a driver for Neopixels, QT Stemma socket, speaker and a battery charger socket.

The board uses a USB-C connector. 
It has a six screw terminals for the three leads for the Neopixels, two for the speaker and one for a button. 
There is a three pin connector for a servo.
The battery connection is top left. It is important to note that this board includes a charging circuit so only use chargeable LiPo batteries or follow the instructions to isolate the charging circuit.


It is important to note that as a power saving feature the Neopixel driver, the servo and the speaker amplifier are only powered when the GPIO23 pin is high (I spent a while trying to find out why the Neopixels were not lighting up until I remembered).

Here is the board operating a Neopixel strip. 


Code to follow.
