When you were a kid you may have learned about the \"buddy\" system, well this product is kinda like that! A board that will watch your QT Py's back and give it the power and support to drive NeoPixel strips, rings, and panels.\u003c\/p\u003e\n\u003cp\u003eThis PCB is designed to fit onto the back of any \u003ca href=\"\/en-eu\/search?q=qt%20py\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eQT Py\u003c\/a\u003e or \u003ca href=\"\/en-eu\/collections\/xiao\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eXiao board\u003c\/a\u003e, it can be soldered into place or use pin and socket headers to make it removable. Onboard is a 74AHCT125 single-gate level shifter that will take pin A3's output, and shift it up to 5V using the USB power as a reference. The USB power, ground and shifted data is then piped out to a JST PH 2mm 3-pin connector.\u003c\/p\u003e\n\u003cp\u003eIf using a NeoPixel strip with a JST-PH connector on them already, you can just plug it right in for instant lights. If you're using a common JST SH (black in-line) connector on the strips, you can use a JST-PH-to-female-header cable and use that to plug into the pins on the input of the SH port and\/or can jam the wires into the header sockets.\u003c\/p\u003e\n\u003cp\u003eNote that Adafruit connect the USB 5V power directly out to the NeoPixel power pin on the JST PH connector and PH connectors are only rated for about 2 Amps, so it's not for powering directly more than maybe 30-60 NeoPixels (less if they're on full white brightness).\u003c\/p\u003e\n\u003cp\u003eAdafruit include some header that you can solder to your QT Py.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eComes as an assembled and tested PCB\u003c\/li\u003e\n\u003cli\u003eFor any QT Py or Xiao boards\u003c\/li\u003e\n\u003cli\u003eUses the 5V input via USB Type-C connector on QT Py to Power 30ish NeoPixels\u003c\/li\u003e\n\u003cli\u003eLevel-shifted data from pin \u003cstrong\u003eA3 default\u003c\/strong\u003e, can solder-jumper select \u003cstrong\u003eSCL\u003c\/strong\u003e, \u003cstrong\u003eTX\u003c\/strong\u003e, \u003cstrong\u003eRX\u003c\/strong\u003e, \u003cstrong\u003eSCK\u003c\/strong\u003e or \u003cstrong\u003eMOSI\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFor driving any WS2812\/WS2811\/NeoPixel LEDs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNeoPixels and QT Py are not included.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cp\u003eProduct Dimensions: 20.9mm x 17.9mm x 7.2mm \/ 0.8\" x 0.7\" x 0.3\"\u003c\/p\u003e\n\u003cp\u003eProduct Weight: 1.6g \/ 0.1oz\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":40420032938067,"sku":"ADA5645","price":4.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/5645-02.jpg?v=1745607419","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-neopixel-driver-bff-add-on-for-qt-py-and-xiao","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
