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 code
Mode 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.
