RFM95/ 96 /97/98(W) @Davet998

Wireless Specifications of RFM95W  168 dB maximum link budget.  +20 dBm - 100 mW constant RF output vs.  +14 dBm high efficiency PA.  Programmable bit rate up to 300 kbps.  High sensitivity: down to -148 dBm.  Bullet-proof front end: IIP3 = -12.5 dBm.  Excellent blocking immunity.  Low RX current of 10.3 mA, 200 nA register retention.  Fully integrated synthesizer with a resolution of 61 Hz.  FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation.  Built-in bit synchronizer for clock recovery.  Preamble detection.  127 dB Dynamic Range RSSI.  Automatic RF Sense and CAD with ultra-fast AFC.  Packet engine up to 256 bytes with CRC.  Built-in temperature sensor and low battery indicator. @Davet998

Power Consumption Caution: Power supply requirements of the RFM module may be relevant in some circumstances: RFM95/96/97/98 modules are capable of pulling 120mA+ at full power, where Arduino's 3.3V line can give 50mA. @Davet998

RadioHead Libraries http://www.airspayce.com/mikem/arduino/RadioHead/index.html RH_RF95 Works with :-  Semtech SX1276/77/78/79  Modtronix inAir4 and inAir9  HopeRF RFM95/96/97/98  and other similar LoRa capable radios. Server Client ‘Hello World’ @Davet998

iC880a Raspberry Pi Gateway Bill of Materials Raspberry Pi 3 £32.80 16Gb Micro SD card £4.65 BackPlane £11.22 IMST iC880a £239.69 pigtail antenna 2A PSU £6.00 Total £294.36 @Davet998

Build  Assemble the backplane  Plug in the Pi, iC880a and antenna  Download the raspbian-jessie-lite image  Configure the Pi  Follow the excellent instructions here to install Gateway https://github.com/ttn-zh/ic880a-gateway/wiki  Remember to note down the mac address!  3D Print a mount for the antenna @Davet998
