LoRa

LoRa is signal modulation providing long range and low power consumption. Great for M2M communication, IoT sensors,etc. To get long range and low power consumption there is no wide bandwidth, but for sensors - ideal radio connectivity.

We liked this board very much, especially when we did created breakout board. With this PCB is much easier to use RA-01 with Arduino or Raspberry. Breakout board was designed with Ra-01 in mind, but it should work with Ra-02 too.

Ra-01 and Ra-02 differ only by antenna connector. Former has place for spring antena, RA-02 has U.FL/IPEX connector for external 433 MHz antenna.

Specification:

• modulation LoRa, FSK, GFSK, MSK, GMSK, OOK
• radio module: SX1278
• receive sensivity even as low as -141 dBm
• SPI inteface (half duplex)
• bit rate up to 300 Kbps
• working frequencies - 410-525 MHz
• U.FL/IPEX antenna connector
