Built in Mass Storage USB with 16 MB storage. Drag and drop your files right on it.

Battery not included

For use with Adafruit LiPoly/LiIon batteries only. Other batteries may have different voltage, chemistry, polarity or pinout. Lipo/Lipoly/LiIon Batteries not included

Comes assembled and tested with a JST cable, 5V input via Micro-B USB connector, For charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells), 100mA charge current, adjustable to 500mA by soldering a jumper closed

Small enough to fit into any project, and low cost enough to use without hesitation.

ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM Internal oscillator runs at 8MHz, but can be doubled in software for 16MHz

USB bootloader with a nice LED indicator & Micro-USB jack for power and/or USB uploading

This battery is for general use. Please make sure this battery will fit your application by measuring against the dimensions below

Add an ear to your project with this well-designed electret microphone amplifier

Built in automatic gain control

Great for when you want to record or detect audio in a setting where levels change

240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS

Integrated 520 KB SRAM

Integrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIP

Si5351A clock generator is an I2C controller clock generator

Precision 25MHz crystal reference

Three independent outputs, each one can have a different frequency

Three axis sensing, 10-bit precision with �2g/�4g/�8g/�16g selectable scaling

Both I2C (2 possible addresses) and SPI interface option

Plus 3 additional ADC inputs you can read over I2C

There's an I2C-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!

It is 5V compliant, which means you can control it from a 3.3V Arduino and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)

6 address select pins so you can stack up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs

Powerful little electronic switch

Control medium-power electronics such as small motors, solenoids, or IR LEDs

Switch up to 40V at peak currents of 1A (not continuously, just peak!), with a DC gain of about 100

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!
