피더 32u4 RFM69HCW LoRa 라디오 -868 / 915MHz
(Adafruit Feather 32u4 RFM69HCW Packet Radio
- 868 / 915 MHz)
개요
- 본 제품은 Atmega32u4 마이크로컨트롤러 및 900MHz RFM69HCW LoRa 라디오 트랜시버를 장착한 개발보드입니다.
- USB와 배터리 충전(3.7V 리포배터리)을 지원하며, 원거리 통신을 하고자 할때 사용이 가능합니다.
- 900Mhz 버전으로 868Mhz 나 915Mhz 무선 전송 수신에 사용이 가능합니다.
- Atmega32u4는 8Mhz에서 동작을 하며, 3.3V 로직과 동작합니다.
- USB기능을 칩에 내장하고 있어 FTDI 칩이 별도로 필요없으며, 마우스, 키보드, USB MIDI 장치 등등으로 동작할 수 있습니다.
- 리포배터리를 꼽은 상태에서 micro USB 포트에 케이블을 연결하면 충전이 됩니다.
- battery를 디바이더를 통해 아날로그 핀으로 연결하여서 배터리 전압 레벨을 모니터링할 후 충전할 수 있습니다.
특징

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
The Feather 32u4 Radio uses the extra space left over to add an RFM69HCW 433 or 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 ned more range than 2.4 GHz (BT, BLE, WiFi, ZigBee)
- SX1231 based module with SPI interface
- Packet radio with ready-to-go Arduino libraries
- Uses the license-free ISM band ("European ISM" @ 868MHz or "American ISM" @ 915MHz)
- +13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
- 50mA (+13 dBm) to 150mA (+20dBm) current draw for transmissions
- Range of approx. 350 meters, depending on obstructions, frequency, antenna and power output
- Create multipoint networks with individual node addresses
- Encrypted packet engine with AES-128
- Simple wire antenna or spot for uFL connector
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!
