HT-AT62 is a cost-effective LoRa node module, it has the characteristics of long communication range, high receive sensitivity, low power consumption and low cost. The HT-AT62 is composed of an MCU (32-bit T-Head Microsystems) and Semtech LoRa Transceivers (SX1262).
Regarding the software side, it already integrated LoRaWAN 1.0.2 protocol with AT command support. This means that when you use the module, you only need to simply send the corresponding information through the UART to achieve LoRaWAN-related configuration and communication. In addition, 10 GPIOs that can be controlled via AT commands to accomplish some simple functions such as HIGH/LOW reversal, input and output, delay inversion and so on.
