Create a heart-felt NeoPixel LED badge using Adafruit's QT Py development board. This is cute project was created for makers getting started with SMD soldering.

This singled-sided PCB features SMD pads for six 5050 NeoPixel LEDs and the Adafruit QT Py. The center cutout allows a SPI flash chip to fit through the board. It's simple, easy to assemble and customizable.

Use a desktop CNC to mill your custom PCBs using FR-1 blanks. You can fit up to four QT Py heart PCBs on a 4x5in PCB blank in less than 10 minutes! 

Use a PCB service like OSHPark to create custom PCBs with beautiful solder mask and silkscreen. Download the CAD file and upload it to have them shipped to you.
