REYAX RYLR406 433MHz LoRa Module Products

Description

The LoRa REYAX RYLR406 module is a radio transceiver designed to work in the 433MHz ISMIndustrial, Scientific, and Medical radio bands band with a frequency range between 390MHz to 525MHz. This module has a typical range of 4.5km and a max range of 15km with a programmable RF power output up to +15dBmDecibel-milliwatts (dBm) is a power level that expresses decibels in terms of milliwatts on a logarithmic scale. (31.6mW), spread spectrum communication, and high interference immunity. Transmission communication is half-duplex and supports FSKFrequency-Shift Keying modulation, GFSKGaussian Frequency-Shift Keying modulation, MSKMinimum-Shift Keying modulation, GMSKGaussian Minimum-Shift Keying modulation, OOKOn-Off Keying modulation, and LoRaLoRa (short for Long Range) is a spread spectrum modulation technique derived from Chirp Spread Spectrum (CSS) technology. modulations.

Data is transmitted in packets with a payload message up to 255 bytes in length, AESAdvanced Encryption Standard (AES) is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. It was developed an alternative to the Data Encryption Standard (DES), which was starting to become vulnerable to brute-force attacks.-128 data encryption, and a 2-byte CRCCyclic Redundancy Check checksum for message error detection, and can communicate with up to 255 modules on the same network that share the same network ID.

The main processor is a Semtech SX1276 ICIntegrated Circuit where data interfacing and control is performed by ATShort text string commands where the AT stands for ATtention and every command line starts with "AT" or "at". commands through 2-wire UARTUniversal Asynchronous Receiver-Transmitter (RXDReceive Data, TXDTransmit Data). Data baud rates are selectable from 300bpsbits per second to 115,200bpsbits per second. The module is powered from 2V to 3.6V DC with a max 43mA transmit current, 16.5mA receive current, and 0.5μA sleep current.

Accessories

The REYAX RYLR406 module comes with a spring antenna, but also has a pad on the back of the board to solder a connector for an IPEX/uFL or SMASubMiniature version A (SMA) connector antenna. This is useful if you want to use a better antenna or have a more flexible position with a cable for the antenna. Below are some options for purchasing antennas and connectors.
