easyRadio Advanced eRA- LoRa Long Range Datasheet Features Chirped Spread Spectrum technology Pin compatible with easyRadio Advanced (eRA) series RF modules uFL RF connector for remote antennas Point to Point communication Half duplex transparent Serial Data Input and Output Up to 180 bytes per packet Familiar easyRadio commands Built in temperature sensor Flash firmware upgrades. New features and updates can be quickly programmed using LPRS tools Product image for illustration purposes only Key Parameters The easyRadio eRA-LoRa (Long Range) RF transceiver Frequency: 868/915MHz module uses Chirped Spread Spectrum (CSS) modulation Receiver sensitivity: down to -137dBm together with DSP (Digital Signal Processing) to achieve Multi-channel operation greater range than traditional devices using OOK, FSK or RF Power output: up to +20dBm (100mW) GFSK modulation. Receive current consumption: 15mA RSSI dynamic range: 127dB In addition, sensitivity and blocking performance are Line of Sight (LoS) range - 1km 3km plus improved giving high interference immunity whilst still offering low power consumption. User Programmable Options: The module is a complete sub-system that combines a high Spreading factors 6: to 12 performance low power RF transceiver, a microcontroller Error correction rate and a voltage regulator. Bandwidth: 125, 250, 500kHz Over air data rates of up to 300 kbps Key operating parameters can be changed and configured by Host Data Rate: 2.4kbps 115.2kbps sending simple text (ASCII character) commands to the module. The variable spreading factor and error correction rate allow the user to optimise the bandwidth to provide a balance between sensitivity (range) and data rate. Applications Required range is above 1km or transceiver is in poor RF location Suburban security alarms - void buildings, caravan or car storage sites, warehouses Rural security, farm buildings/equipment, livestock monitoring, remote irrigation pumps Data collection and monitoring over a wide area eRA LoRa FCC V1.22.docx Page 1 of 9 easyRadio Advanced eRA-LoRa Long Range Datasheet FCC Warning Statement: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Canada Warning Statement: English: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. French: Conformment la rglementation d Industrie Canada, le prsent metteur radio peut fonctionner avec une antenne d un type et d un gain maximal (ou infrieur) approuv pour l metteur par Industrie Canada. Dans le but de rduire les risques de brouillage radiolectrique l intention des autres utilisateurs, il faut choisir le type d antenne et son gain de sorte que la puissance isotrope rayonne quivalente (p.i.r.e.) ne dpasse pas l intensit ncessaire l tablissement d une communication satisfaisante. Le prsent appareil est conforme aux CNR d Industrie Canada applicables aux appareils radio exempts de licence. L exploitation est autorise aux deux conditions suivantes : (1) l appareil ne doit pas produire de brouillage, et (2) l utilisateur de l appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d en compromettre le fonctionnement. eRA LoRa FCC V1.22.docx Page 2 of 9
