QT Py Boards are a great way to make very small microcontroller projects that pack a ton of electricity - and now there's a way to quickly add a touch of NeoPixels with a 5V level switch and a detachable JST PH connector. It is an excellent way to make small portable, cosplay or IoT projects with dazzling LEDs.
The Adafruit NeoPixel DriverBFF is a "Best Friend Forever". If you were a child, you may have learned about the "Buddy" system, then this product is so simple. A board that observes the back of your QT Py and gives it the power and support to drive NeoPixel strips, rings and panels.
This PCB is designed to fit the back of any QT Py or Xiaoboard, it can be soldered in place or with pin and female headers to make it removable. Onboard is a 74AHCT125 single gate level shifter, which takes the output of the pin A3 and shifts it up to 5V with the USB power supply for reference. The USB power supply, grounding and wired data are then fed to a JST PH 2mm 3-pin connector.
If you use a NeoPixel strip with a JSTPHH connector, you can simply plug it in for instant glow. If you use an ordinary JST-SH male (black inline) connector on the strips, you can use a JSTPH-to-female head cable and use it to plug into the pins at the input of the SH port and/or clamp the wires into the header sockets.
This includes some headers that you can solder to your QT Py. You can also accommodate an Itsy Bitsy short socket header set to make it removable but compact. You only need to shorten the header to 7 pins.
