It features a 64MHz ARM Cortex M4F processor with hardware floating point, 512KB flash, 64KB SRAM, built-in USB serial converter, battery charging, and a robust 2.4GHz BLE radio. Designed for efficient, low-power wireless projects, it supports direct programming via Arduino IDE without auxiliary microcontrollers, making it ideal for professional-grade IoT and wearable applications. ## Description ARM Cortex M4F (with HW floating point acceleration) running at 64MHz 512KB flash and 64KB SRAM Built in USB Serial converter for fast and efficient programming and debugging Bluetooth Low Energy compatible 2.4GHz radio (Details available in the nRF52832 product specification) FCC / IC / TELEC certified module Up to +4dBm output power 1.7v to 3.3v operation with internal linear and DC/DC voltage regulators 19 GPIO, 8 x 12-bit ADC pins, up to 12 PWM outputs (3 PWM modules with 4 outputs each) Pin #17 red LED for general purpose blinking Power/enable pin Measures 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 4 mounting holes Reset button Optional SWD connector for debugging Review: Read Adafruit's information and technical before writing a bad review. - This board works as described, so long as you read the notes about this device on Adafruit's page. I've read a few reviews about this product and I have to really wonder if they did any of that. The first thing you need to do is to upgrade the bootloader. Easy enough following Adafruit's directions and Arduino IDE. Also, do not pair the device before running the Adafruit App, or you will not see it in the App. Following these simple instructions will save you much grief and also prevent you from leaving a 1 star review and looking silly as everyone else follows the instructions and winds up having no troubles. Review: Incredible board! - Blazing fast, super low power consumption, and bluetooth works well for my bluetooth HID keyboard application. Be ware that certain libraries won't work for this if they haven't been ported to the NRF52 chipset yet (mainly anything that's chip specific such as setting PWM frequency or triggering low-power mode). Adarfuit has a quite complete "Adafruit_nRF52_Arduino" git repo for their library with great examples that work flawlessly out of the box. Would buy again for my next bluetooth project. ## Features - The Adafruit Feather nRF52 Bluefruit is an easy-to-use all-in-one Bluetooth Low Energy board, with a native-bluetooth chip, the nRF52832! It's our take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB and battery charging. - This chip has twice the flash, SRAM and performance of the earlier nRF51-based Bluefruit modules. Best of all it has Arduino IDE support so there is no 'helper' chip like the ATmega32u4 or ATSAMD21. Instead, this chip is programmed directly! It's got tons of awesome peripherals: plenty of GPIO, analog inputs, PWM, timers, etc. Leaving out the extra microcontroller means the price, complexity and power-usage are all lower/better. - It allows you to run code directly on the nRF52832, straight from the Arduino IDE as you would with any other MCU or Arduino compatible device. A single MCU means better performance, lower overall power consumption, and lower production costs if you ever want to design your own hardware based on your Bluefruit nRF52 Feather project! - The chip comes pre-programmed with an auto-resetting bootloader so you can upload quickly in the Arduino IDE with no button-pressing. Want to program the chip directly? You can use our command line tools with your favorite editor and toolchain. - The example code works great with Adafruit's existing iOS and Android app. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071ZSQDSJ | | Best Sellers Rank | #924 in Single Board Computers (Computers & Accessories) | | Customer Reviews | 4.5 4.5 out of 5 stars (75) | | Date First Available | March 30, 2017 | | Is Discontinued By Manufacturer | No | | Item Weight | 3.52 ounces | | Item model number | 4328317162 | | Manufacturer | Adafruit | | Product Dimensions | 0.31 x 1.97 x 0.91 inches | ## Product Details - **Brand:** Adafruit - **CPU Speed:** 64 MHz - **Memory Storage Capacity:** 512 KB - **Model Name:** nRF52832 - **Ram Memory Installed Size:** 64 KB ## Images ![Feather nRF52 Bluefruit LE - nRF52832 - Image 1](https://m.media-amazon.com/images/I/71n1IWQAexL.jpg) ## Questions & Answers **Q: Is the logic level 3.3v or 5v?** A: 3.3v. You will need a level shifter to talk to 5v. Been looking into that recently as I found a great deal on a 5v led matrix. **Q: Can i get schematics, and pcb gerber files(or pcb gerber picture files)?** A: not sure about the gerber file, but I did find schematics. **Q: Does it come with the 16 pin connector strips?** A: Yeah **Q: Can you connect a bme280 to this and use the feather to bt the data back to the rp4b?** A: Yes, the humidity sensor can make use of i2c or spi and send the data to your pi via BT. If you use the serial transfer service it will be very easy. You’ll need puiiup resistors for the i2c pins, start at 10k. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Read Adafruit's information and technical before writing a bad review. *by S***N on October 24, 2019* This board works as described, so long as you read the notes about this device on Adafruit's page.

Range was a bit low, maybe 15 feet for my HID application but i can live with it. I only wish win7 had ble support ## Frequently Bought Together - Adafruit Feather nRF52 Bluefruit LE - nRF52832 - Adafruit HUZZAH32 – ESP32 Feather Board - Adafruit Feather Stacking Headers - 12-pin and 16-pin female headers [ADA2830] --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/487422918-feather-nrf52-bluefruit-le-nrf52832](https://www.desertcart.ie/products/487422918-feather-nrf52-bluefruit-le-nrf52832) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-24*
