It features 32KB of Flash and 2KB of RAM, along with native USB support. This means no separate USB-to-serial converter chip is required, and the board can also emulate USB devices such as a mouse, keyboard, or MIDI device. The Feather 32u4 is fully supported in the Arduino IDE and works with a wide range of existing sensors and libraries.\u003c\/p\u003e\n\u003cp\u003eFor portable use, the board includes a JST connector for 3.7V Lithium polymer batteries and built-in battery charging. It can run directly from the micro USB connector without a battery, or automatically switch to USB power when connected for charging. A built-in voltage divider connects the battery to an analogue pin, allowing you to monitor battery voltage in software.\u003c\/p\u003e\n\u003cp\u003eThe Basic Proto version includes a small onboard prototyping area, making it easy to add simple components such as buttons or sensors without needing a separate breadboard.\u003c\/p\u003e\n\u003cp\u003eEach board comes fully assembled and tested, with a USB bootloader pre-installed for quick setup in the Arduino IDE. Header pins are included (unsoldered) for use with breadboards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e Lipoly battery, breadboard and USB cable are not included.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/NneG1LLdyxs?si=DBpG3Bw3d5H56_tY\u0026amp;start=736\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eATmega32u4 @ 8MHz with 3.3V logic\/power\u003c\/li\u003e\n\u003cli\u003e3.3V regulator with 500mA peak current output\u003c\/li\u003e\n\u003cli\u003eUSB native support, comes with USB bootloader and serial port debugging\u003c\/li\u003e\n\u003cli\u003eYou also get tons of pins - 20 GPIO pins\u003c\/li\u003e\n\u003cli\u003eHardware Serial, hardware I2C, hardware SPI support\u003c\/li\u003e\n\u003cli\u003e7 x PWM pins\u003c\/li\u003e\n\u003cli\u003e10 x analogue inputs (one is used to measure the battery voltage)\u003c\/li\u003e\n\u003cli\u003eBuilt in 100mA lipoly charger with charging status indicator LED\u003c\/li\u003e\n\u003cli\u003ePin #13 red LED for general purpose blinking\u003c\/li\u003e\n\u003cli\u003ePower\/enable pin\u003c\/li\u003e\n\u003cli\u003e4 mounting holes\u003c\/li\u003e\n\u003cli\u003eReset button\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMeasures: 51mm x 23mm x 8mm without headers\u003c\/li\u003e\n\u003cli\u003eWeight: 4.8 grams\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRevision History\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of July 26, 2023\u003c\/strong\u003e – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003cli\u003eTutorial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Adafruit Feather 32u4 Basic Proto\u003c\/li\u003e\n\u003cli\u003e2x 16-pin header\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48623664595162,"sku":"kiq1789675045105","price":19.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/adafruit-feather-32u4-basic-proto_1.jpg?v=1789675072","url":"https:\/\/memoryfoamwear.shop\/products\/adafruit-feather-32u4-basic-proto","provider":"My Store","version":"1.0","type":"link"}
