User equipment can interact with the module through the serial communication interface (UART). The module supports AT command set, firmware upgrade, AES encryption, low power consumption, network activation and other functions. It has rich peripheral interfaces (UART, ADC, SPI, I2C, GPIOs, USB, etc.), providing users with flexible and simple LoRaWAN network data access operations.
The WSL01-A0 module can be applied to wireless sensors, wearable devices and other battery-powered low-power IoT devices.
