Adafruit Feather M0 with RFM95 LoRa Radio - 868-900MHzFeather 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 M0 RFM95 LoRa Radio (900MHz) our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging.

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 M0 RFM95 LoRa Radio (900MHz) - our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather M0 with a 900MHz radio module cooked in! Great for making wireless networks that are more flexible than Bluetooth LE and without the high power requirements of WiFi. We have other boards in the Feather family, check'em out here.
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. We also sell a 433MHz version of the same radio chipset!
At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.
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 M0's you get:
- Measures 2.0" x 0.9" x 0.3" (51mm x 23mm x 8mm) without headers soldered in
- Light as a (large?) feather - 5.8 grams
- ATSAMD21G18 @ 48MHz with 3.3V logic/power
- No EEPROM
- 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
- 1 x analog output
- 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 M0 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).
- SX127x 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!

A Must-Have for History Enthusiasts and Young Readers!
Format: Paperback
As an avid history enthusiast and a parent, I am always on the lookout for engaging and educational books that can captivate my children's interest in the subject. "Great Battles for Boys: Bunker Hill to WWI" exceeded my expectations on all fronts, making it an absolute gem in our family library.
From the moment I picked up this book, I was impressed with the attention to detail and the beautifully presented information. The author, Joe Giorello, has a remarkable talent for simplifying complex historical events and presenting them in a manner that is both informative and accessible to young readers. This book is perfectly suited for boys aged 8-12, but it can certainly be enjoyed by readers of all ages.
The book takes readers on an incredible journey through some of the most significant battles in history, covering a wide range of conflicts from the American Revolution to World War I. Each battle is meticulously described, allowing young readers to visualize and understand the strategies, key figures, and outcomes of these momentous events. The inclusion of maps, illustrations, and photographs further enhances the reading experience, making it all the more immersive.
One aspect that sets "Great Battles for Boys" apart from other history books is its interactive nature. Throughout the chapters, readers are encouraged to actively engage in the material through trivia questions, hypothetical scenarios, and thought-provoking discussion points. This interactive approach not only keeps young readers engaged and entertained but also encourages critical thinking and a deeper understanding of the subject matter.
Additionally, I appreciated the inclusion of personal stories and firsthand accounts, which added a human element to the historical events. By highlighting the experiences of individual soldiers and their contributions, this book successfully humanizes the battles and helps young readers relate to the courageous men who fought on the frontlines.
In terms of writing style, Giorello has a knack for keeping the narrative engaging and exciting without sacrificing historical accuracy. The pacing is well-balanced, and the author's passion for history shines through in every chapter. It's clear that extensive research was conducted, and the information is presented in a manner that is both educational and entertaining.
In conclusion, "Great Battles for Boys: Bunker Hill to WWI" is an outstanding resource for history enthusiasts and young readers alike. With its engaging writing style, interactive elements, and comprehensive coverage of pivotal battles, this book is an excellent addition to any library. Highly recommended!

8yo son and mom love this book
Format: Paperback
I’m a mom of two boys and one girl. I would first like to address the people complaining about the title saying “for boys.” The author has addressed this too and it’s part of the reason why I purchased this book. Boys are falling behind in school and reading. Not sure why some people are allowed to review these books when they haven’t read them or purchased them. Do your research if you have a boy in your life. I would also like to point out that bookstores frequently have shelves dedicated to girls about strong women, strong girls, etc and yes boys can read books in those sections just like girls can read these Great Battles for Boys books.
My 8yo son loves history and is devouring this book. I highly recommend. This book is really exciting and I (mom) am enjoying it too. We use it for read aloud time and independent reading. As soon as I finish this review I will be ordering more in the series, per my sons request.
