[Introduction]：E77-400M22S series products are standard LoRaWan node modules designed and produced by Ebyte, with an operating frequency band of 410~510MHZ, supporting LoRaWAN 1.0.3 EU433/CN470 standards, supporting CLASS-A/CLASS-C node types, and supporting ABP/OTAA network access methods. At the same time, the LoRa module has a variety of low-power modes, and the external communication interface uses a standard UART. Users can access the standard LoRaWAN network through simple configuration of AT commands, which is an excellent choice for current IoT applications.

Note
1: PA6 and PA7 pins are used as internal control RF switches of the
module. PA6 = RF_TXEN, PA7 = RF_RXEN. RF_TXEN=1 and RF_RXEN=0 are the
transmit channels, and RF_TXEN=0 and RF_RXEN=1 are the receive channels.
Note
2: The PC14-OSC32_IN and PC15-OSC32_OUT pins have a 32.768kHz crystal
oscillator internally connected to the module for users to choose during
secondary development.
Note 3: The OSC_IN and OSC_OUT pins have a 32MHz crystal oscillator connected inside the module for users to choose to use during secondary development.
