MakerFocus 868 MHZ LoRa Spread-Spectrum Communication UART SX1276 Chip RF Receiver Transmitter

Description:This is a 100mW UART transparent and transmission wireless transceiver module, operates at 862~893MHz, based on original imported RFIC SX1276 from SEMTECH. The module integrates the function of receiving and sending information, adopts LoRa spread-spectrum technology, which means the transmitting distance and penetration capacity are one time more than that of traditional Frequency-shift Keying.At the same time, using the FEC forward error correction algorithm, it can actively correct the interfered data packets, making the communication distance farther, the anti-interference ability stronger, and having the air wake-up function (ultra-low power consumption).Four Working Modes:Mode 0:  General mode: M0=0, M1=0; Low power consumption Occasion (Most occasions)Mode 1: Wake mode: M0=1, M1=0; Using low power consumption, it's the mode of the transmitting party, automatically adding the wake-up codeMode 2: Power saving mode: M0=0, M1=1; Using low power consumption, it's the mode of the receving party, cannot transmit in this mode.Mode 3: Sleep mode: M0=1, M1=1; Using low power consumption, it's the mode of the receving party, cannot transmit in this mode. The module is in a sleep state and can accept parameter setting commands.Parameter:Chip:  SX1276 Model: E32-868T20DTransmit power: 100mWCommunication Distance: 3000mRF connector: SMA-KWorking frequency:862~893 MHz (Default: 868MHz)            Transmitting power:10~20 dBm, Default: 20dBm    Receiving sensitivity: -146 dBmAir data rate: 0.3k~19.2kbps(Default: 2.4kbps) Size: 21 * 36 mm(Without SMA)        Antenna type: SMA-K (Not inclueded)         Communication interface: UART (Baud rate: 1200~115200, default: 9600)        Buffer: 512 bytes buffer (Automatically sub-packaging with 58 bytes per package)   Packing List: 1 * 868 MHZ UART SX1276 LoRa RF Receiver Transmitter
