Adafruit Feather M0 with RFM95 LoRa Radio - 900MHz

• Adafruit Feather M0 RFM95 LoRa Radio - 900MHz<br />
• 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)

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. If 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. Features: 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).
