Adafruit Feather M0 with RFM95 LoRa Radio

Description: Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! They designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit Feather M0 RFM95 LoRa Radio (900MHz) - their take on an microcontroller with a 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. 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 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 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 inLight as a (large?) feather - 5.8 gramsATSAMD21G18 @ 48MHz with 3.3V logic/powerNo EEPROM3.3V regulator with 500mA peak current outputUSB native support, comes with USB bootloader and serial port debuggingYou also get tons of pins - 20 GPIO pinsHardware Serial, hardware I2C, hardware SPI support8 x PWM pins10 x analog inputs1 x analog outputBuilt in 100mA lipoly charger with charging status indicator LEDPin #13 red LED for general purpose blinkingPower/enable pin4 mounting holesReset 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 interfacePacket radio with ready-to-go Arduino librariesUses 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. 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!Visit Our eBay Store: Chicago Electronic Distributors
