Summary
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.
It can be widely and easily used in smart cities, farms, homes, industrial controls, wireless meter reading, etc. fields.
Main Features
- LoRaWAN 1.0.2 protocol with AT command supports;
- 32-bit high-performance and low-cost microcontroller and SX1262;
- Low power design, 12uA in deep sleep mode;
- 1.27 stamp edge design, friendly for batch SMT producing;
- Good impendence matching and long communication distance;
- GPIO HIGH/LOW control via AT commands;
