Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

This is the Adafruit Feather 32u4 LoRa Radio (RFM9x) - our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather 32u4 with a 868/915 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GHz 802.15.4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi.

This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically.

At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as it's the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

Here's some handy specs! Like all Feather 32u4's you get:

• Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in
• Light as a (large?) feather - 5.5 grams
• ATmega32u4 @ 8MHz with 3.3V logic/power
• 3.3V regulator with 500mA peak current output
• USB native support, comes with USB bootloader and serial port debugging
• You also get tons of pins - 20 GPIO pins
• Hardware Serial, hardware I2C, hardware SPI support
• 8 x PWM pins
• 10 x analog inputs
• Built 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

This Feather 32u4 LoRa Radio uses the extra space left over to add an RFM9x LoRa 868/915 MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee).

• SX1276 LoRa® based module with SPI interface
• Packet radio with ready-to-go Arduino libraries
• Uses the license-free ISM bands (ITU "Europe" @ 433MHz and ITU "Americas" @ 900MHz)
• +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
• ~300uA during full sleep, ~120mA peak during +20dBm transmit, ~40mA during active radio listening.
• Simple wire antenna or spot for uFL connector

Our initial tests with default library settings: over 1.2mi/2Km line-of-sight with wire quarter-wave antennas. (With setting tweaking and directional antennas, 20Km is possible).

Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some headers so you can solder it in and plug into a solderless breadboard. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Lipoly battery and USB cable not included but we do have lots of options in the shop if you'd like!

Say "Hi!" to the WICED Feather! Perfect for your next Internet connected project, with a powerful processor and WiFi core that can take anything you throw at it.

Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit WICED Feather - it's our most powerful Feather yet!

The WICED Feather is based on Cypress (formerly Broadcom) WICED (Wireless Internet Connectivity for Embedded Devices) platform, and is paired up with a powerful STM32F205 ARM Cortex M3 processor running at 120MHz, with support for TLS 1.2 to access sites and web services safely and securely.

We spent a lot of time adding support for this processor and WiFi chipset to the Arduino IDE you know and love. Programming doesn't rely on any online or closed toolsets to build, flash or run your code. You write your code in the Arduino IDE using the same standard libraries you've always used (Wire, SPI, etc.), compile locally, and the device is flashed directly from the IDE over USB.

Since the WICED Feather is based on the standard Adafruit Feather layout, you also have instant access to a variety of Feather Wings, as well as all the usual standard breakouts available from Adafruit or other vendors.

After more than a year of full time effort in the making, we think it's the best and most flexible WiFi development board out there, and the easiest way to get your TCP/IP-based project off the ground without sacrificing flexibility or security. We even cooked in some built-in libraries in the WiFi core, such as TCP client and Server, HTTP client and server, and MQTT client (with easy Adafruit IO interfacing). It can even work with Amazon AWS IoT!

Please note: this is a really cool product but it's also very advanced and there may be firmware updates, tweaks and fixes as we have more people use it. For that reason we are calling this the Developer Edition! This chipset is not identical to the Arduino standard-supported Atmega series and many libraries that are written specifically for AVR will not compile or work with the STM32!

The WICED Feather has the following key features:

• 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
• STM32F205RG 120MHz ARM Cortex M3 MCU
• BCM43362 802.11b/G/N radio
• 128KB SRAM and 1024KB flash memory (total)
• 16KB SRAM and 128KB flash available for user code
• 16MBit (2MB) SPI flash for additional data storage
• Built in Real Time Clock (RTC) with optional external battery supply
• Hardware SPI and I2C (including clock-stretching)
• 12 standard GPIO pins, with additional GPIOs available via SPI, UART and I2C pins
• 7 standard PWM outputs, with additional outputs available via SPI, UART and I2C pins
• Up to eight 12-bit ADC inputs
• Two 12-bit DAC outputs (Pin A4)
• Up to 3 UARTs (including one with full HW flow control)
• TLS 1.2 support to access secure HTTPS and TCP servers
• On board single-cell LIPO charging and battery monitoring
• Fast and easy firmware updates to keep your module up to date
• Based on the excellent community-supported Maple project

The Adafruit Gemma M0 is a super small microcontroller board, with just enough built-in to create many simple projects. It may look small and cute: round, about the size of a quarter, with friendly alligator-clip sew pads. But do not be fooled! The Gemma M0 is incredibly powerful! We've taken the same form factor we used for the original ATtiny85-based Gemma and gave it an upgrade. The Gemma M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse.

The Gemma M0 will super-charge your wearables! It's just as small, and it's easier to use, so you can do more.

The most exciting part of the Gemma M0 is that while you can use it with the Arduino IDE, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. When you're done, unplug the Gemma M0 and your code will go with you.

Here are some of the updates you can look forward to when using Gemma M0:

• Same size, form-factor, and pinout as classic Gemma
• Updating ATtiny85 8-bit AVR for ATSAMD21E18 32-bit Cortex M0+
• 256KB Flash - 8x as much as 8 KB on ATtiny85
• 32 KB RAM - 64x as much as 512 bytes on ATtiny85
• 48 MHz 32 bit processor - 6x as fast as ATtiny85 (not even taking into account 32-bit speedups)
• Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts. (ATtiny85 does not have native USB)
• Can be used with Arduino IDE or CircuitPython
• Built in RGB DotStar LED
• Three big-hole sew-pads can be used for conductive thread or alligator-clips for fast prototyping
  • Each I/O pad can be used for 12-bit analog input, or digital input/output with internally connected pullups or pulldowns
  • We gave the M0 pads the exact same names as the original Gemma so all your existing Arduino code will work exactly the same as-is without changes
  • True analog output on one I/O pad - can be used to play 10-bit quality audio clips
  • Two high speed PWM outputs on other two I/O Pads - for servos, LEDs, etc
  • All three pads can also be used as hardware capacitive touch sensors with no additional components required
  • Can drive NeoPixels or DotStars on any pins, with enough memory to drive 8000+ pixels. DMA-NeoPixel support on one pin so you can drive pixels without having to spend any processor time on it.
  • Native hardware I2C or Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging)
• Same Reset switch for starting your project code over
• On/Off switch built in
• JST battery connector for plugging in AAA's or LiPoly battery (no built-in LiPoly charging so it is safe to use with NiMH/Alkalines)

Each order comes with one fully assembled and tested Gemma M0 with CircuitPython & example code programmed in.
