We designed Feather to be a new standard for\nportable microcontroller cores. This is the Adafruit Feather 32u4 Bluefruit\nwith Headers - our take on an 'all-in-one' Arduino-compatible + Bluetooth Low\nEnergy with built in USB and battery charging. Its an Adafruit Feather 32u4\nwith a BTLE module, ready to rock! We have other boards in the Feather family,\ncheck'em out here. For the Feather 32u4 without pre-soldered headers, check\nout this link. Bluetooth Low Energy is the hottest new low-power, 2.4GHz\nspectrum wireless protocol. In particular, its the only wireless protocol that\nyou can use with iOS without needing special certification and it's supported\nby all modern smart phones. This makes it excellent for use in portable\nprojects that will make use of an iOS or Android phone or tablet. It also is\nsupported in Mac OS X and Windows 8+. At the Feather 32u4's heart is at\nATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of\nexperience with as it's the same as the Flora. This chip has 32K of flash and\n2K of RAM, with built in USB so not only does it have a USB-to-Serial program\n\u0026amp; debug capability built in with no need for an FTDI-like chip, it can also\nact like a mouse, keyboard, USB MIDI device, etc. To make it easy to use for\nportable projects, we added a connector for any of our 3.7V Lithium polymer\nbatteries and built in battery charging. You don't need a battery, it will run\njust fine straight from the micro USB connector. But, if you do have a\nbattery, you can take it on the go, then plug in the USB to recharge. The\nFeather will automatically switch over to USB power when its available. We\nalso tied the battery thru a divider to an analog pin, so you can measure and\nmonitor the battery voltage to detect when you need a recharge.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eATmega32u4 @ 8MHz with 3.3V logic\/power\u003c\/li\u003e\n \u003cli\u003eYou also get tons of pins - 20 GPIO pins Hardware Serial, hardware I2C, hardware SPI support 7 x PWM pins 10 x analog inputs\u003c\/li\u003e\n \u003cli\u003e3.3V regulator with 500mA peak current output USB native support, comes with USB bootloader and serial port debugging\u003c\/li\u003e\n \u003cli\u003eBuilt in 100mA lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking Power\/enable pin 4 mounting holes Reset button\u003c\/li\u003e\n \u003cli\u003eMeasures 2.0\" x 0.9\" x 0.28\" (51mm x 23mm x 8mm) without headers soldered in Light as a (large?) feather - 5.7 grams\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2025-10-24T10:27:45+11:00","created_at":"2025-10-24T10:27:43+11:00","vendor":"Adafruit","type":"Single Board Computers","tags":["electronics_selected_Oct2025","weight_unknown"],"price":24000,"price_min":24000,"price_max":24000,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":48915355599085,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B071HTMXCH","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit (PID 3379 Feather 32u4 Bluefruit LE with Headers - Assembled","public_title":null,"options":["Default Title"],"price":24000,"weight":0,"compare_at_price":null,"inventory_management":"shopify","barcode":"717520031444","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/leoforward.com\/cdn\/shop\/files\/B071HTMXCH.jpg?v=1775799078","\/\/leoforward.com\/cdn\/shop\/files\/51QNCP6YGjL.jpg?v=1761262065","\/\/leoforward.com\/cdn\/shop\/files\/51B5TljspAL.jpg?v=1761262065"],"featured_image":"\/\/leoforward.com\/cdn\/shop\/files\/B071HTMXCH.jpg?v=1775799078","options":["Title"],"media":[{"alt":null,"id":36968926445805,"position":1,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/files\/B071HTMXCH.jpg?v=1775799078"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/B071HTMXCH.jpg?v=1775799078","width":500},{"alt":null,"id":36968926478573,"position":2,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/files\/51QNCP6YGjL.jpg?v=1761262065"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/51QNCP6YGjL.jpg?v=1761262065","width":500},{"alt":null,"id":36968926511341,"position":3,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/files\/51B5TljspAL.jpg?v=1761262065"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/51B5TljspAL.jpg?v=1761262065","width":500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eAdafruit (PID 3379 Feather 32u4 Bluefruit LE with Headers - Assembled\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eFeather is the new development board from Adafruit, and like its namesake it\nis thin, light, and lets you fly!
