MPM3610 3.3V Buck Converter Breakout – 21V In 3.3V Out at 1.2A: This little buck converter based on the MPM3610 is a marvel, taking up to 21V input and providing a 3.3V output with up to 1.2A current. It’s great for supplying power to popular 3.3V voltage circuits from a range of battery or power options. This chip provides up to 1.2 Amp load current across the entire input voltage range of 4.5 to 21V. The high voltage range is what sets this buck converter apart from most, as many converters max out at ~6 VDC input.
Adafruit Micro SD SPI or SDIO Card Breakout Board – 3V ONLY!: Micro SD cards and microcontrollers go together like micro-peanutbutter-and-jelly: SD cards are inexpensive, durable, easy to find at any shop, come in many sizes and can plug into any computer using a common SD card reader. That makes them perfect for microcontroller storage and retreival – whether it’s images, fonts, GIFs, audio files, or sensor logs.
2.1mm 5VDC Barrel Jack to USB C Adapter: As technology changes and adapts, so does Adafruit, and speaking of adapting, this adapter has a 2.1mm barrel jack socket and a USB C plug – you could use this to power a USB C device from a common wall adapter.
Black LED Diffusion Acrylic Panel 12″ x 12″ – 0.1″ / 2.6mm thick: A nice whoppin’ slab of some lovely black acrylic to add some extra diffusion to your LED Matrix project. This material is 2.6mm (0.1″) thick and is made of special cast acrylic that makes it perfect for glowy projects, especially matricies or NeoPixels.
Unlike smoke or other-tinted acrylic, this material sharpens the pixels, and reduces the glare. You get a great looking display, all colors are vivid and readable indoors and out!
