The SparkFun Kit features a LoRa SX1276-based 915MHz unlicensed band radio with 902-928MHz configurable output, 256-bit AES GCM encryption, AT command set, built-in Frequency Hopping Spread Spectrum (FHSS) technology, point-to-point and multipoint configurations, 3D printed enclosure (may darken over time), configurable air speeds from 400 bps (40 bytes per second) to 19200bps (1920 bytes per second), configurable standard serial data rates from 2400 to 115200bps, 4-LED RSSI indicator, 3.3 to 5V operation, USB-C connection available for industrial systems and single-board computers (SBCs like Raspberry Pi), 6-pin JST connector available for embedded systems (5V and 3.3V tolerant I/O) with flow control, small footprint, lightweight, easily mountable, and open source software and hardware with 1 Watt (30dBm) power output.
This kit is a pair of serial radio modems that simply passes serial back and forth between one another, allowing you to report data every few seconds even if it’s located beyond WiFi or Bluetooth® range. We’ve been able to successfully transmit data over a 9mi (15km) line-of-sight using two LoRaSerial radios with a larger 5.8dBi antenna on the transmitter and the stock 1/2 wave dipole antenna on the receiver.
The SparkFun LoRaSerial Kit is a great way to transmit data over LoRa, providing you with a range far greater than that of WiFi or Bluetooth®.
