Adafruit 5x5 NeoPixel Grid BFF Add-On for QT Py

This PCB is designed to fit onto the back of any QT Py board, it can be soldered into place or use pin and socket headers to make it removable. Onboard is a grid of 25 1.5x1.5mm NeoPixel LEDs (SK6805 to be exact), connected to pin A3 by default. You can cut/solder some jumpers to select A1, or A2 instead if you like. There's also solder pads for 5V, GND and IN data, in case you want to power externally. Advanced solderer's can use a thin wire to connect from the IN pad to other GPIO pins if desired.

Features:

• Comes as an assembled and tested PCB
• For any QT Py boards
• Uses the 5V input via USB Type-C connector on QT Py to Power 25 NeoPixels
• Default connected to pin A3 for NeoPixel data line. Not level shifted but the SK6805's are happy to run at 5V power with 3V input logic level
