RF1276
LoRa module
V3.0
1. General
RF1276 series is a low cost, ultra-low power, high performance transparent two way semi-duplex LoRa
modulation transceiver with operation at 915Mhz band. It integrates with high speed MCU from ST and high
performance RF IC SX1276. Adopting high efficiency forward error correction with interleaving encoding
(FEC) technology, it makes anti-interference ability and reception sensitivity greatly improved. That
guarantees good performance in the harsh environment such as some industrial application. The FEC
technique is advanced and unique in radio data communication field.
RF1276 has the UART/RS232/RS485 interface, that make it is easy to implement wireless data
transmission. It is flexible for users to set the baud rate, frequency, output power, air data rate etc parameters.
It can transmit transparent data with large data buffer and also can provide over 32 channels. The compact
size makes it an ideal option for radio data communication application.

  • Page 4 RF1276 LoRa module V3.0 Timing Sequence in Standard Mode b. Low power mode In this mode RF1276 enables serial port and CAD monitor which means the module monitors the wireless link periodically. When it detects the wireless signal in the wake-up period, it will open the receive circuit, pick out the effective data and transfer it to the host through the serial port.
  • Page 5 RF1276 LoRa module V3.0 c. Sleep mode In this mode most functions of the modules are disabled so if two modules are set to the Sleep Mode, they can’t communicate with each other so one module must be in Low Power Mode. Comparing to Low Power Mode, the modules in SLEEP MODE will not enable serial port and only keeps CAD monitor.

    RF1276 LoRa module V3.0 Please note that the working modes changed by the 0x03, 0x04 and 0x05 commands will not be written into nonvolatile memory so the working mode will be restored to the former mode before change after power-off. Users can use the WRITE command to change the working mode of module to standard mode or low power mode but the sleep mode will be restored to standard mode after next power-on even if the WRITE command is used.
