Unlike earlier Bluefruit Feathers that used a separate helper chip, the nRF52832 runs your application code and handles BLE directly — resulting in lower power consumption, lower cost, and better performance.\n\nThe nRF52832 features a 64 MHz Cortex M4F with hardware floating point, 512 KB flash, and 64 KB SRAM — twice the resources of the earlier nRF51-based modules. It supports the standard Nordic UART service for transparent data transfer, custom GATT services, HID keyboard emulation, heart rate monitoring, beacon advertising, and over-the-air firmware updates.\n\nKey Features\n\n\nnRF52832 Processor – ARM Cortex M4F at 64 MHz with hardware floating point acceleration\n\n512 KB Flash + 64 KB SRAM – Twice the memory of nRF51-based modules\n\nBluetooth Low Energy – 2.4 GHz BLE radio with up to +4 dBm output power\n\nFCC / IC / TELEC Certified – Pre-certified wireless module\n\nArduino IDE Support – Program directly with the Adafruit nRF52 board support package\n\nAuto-reset Bootloader – Upload code via USB without pressing any buttons\n\nOTA Updates – Flash firmware wirelessly via the Nordic or Adafruit apps\n\nUART Service – Transparent BLE data pipe to iOS and Android via the Bluefruit Connect app\n\nHID Keyboard – Act as a Bluetooth keyboard for compatible devices\n\n19 GPIO Pins – 8× 12-bit ADC, up to 12 PWM outputs (3 modules × 4 channels)\n\nBuilt-in USB Serial – Fast programming and debugging\n\nLiPo Battery Support – JST connector with built-in charger and battery voltage monitoring\n\nOptional SWD Connector – Solder pads for advanced debugging with a CMSIS-DAP or J-Link\n\nCompact Design – 51 mm × 23 mm × 8 mm, weighing 5.7 g\n\n\nAlso Available\n\n\nFeather nRF52 Pro – Same hardware with Apache Mynewt bootloader (advanced users)\n\nFeather nRF52840 Express – Upgraded nRF52840 with USB native, 1 MB flash, CircuitPython\n\nFeather nRF52840 Sense – nRF52840 with on-board sensors\n\n\nIdeal For\n\nBluetooth Low Energy projects with iOS and Android\nWireless sensors and data logging\nBLE HID keyboards and controllers\nBeacon and proximity applications\n\n\nPackage Contents\n\n1× Feather nRF52 Bluefruit LE (nRF52832)\n1× Header pin set\n\n\n\nNote: LiPo battery and USB cable sold separately. FeatherWings that require hardware UART (such as GPS FeatherWing) are not compatible.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13350,"title":"Default Title","sku":"AF-3406","price":50.48,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
