The HT-RA62 LoRa Series Module is used for ultra-long-range spread spectrum communication, and its chip SX1262 mainly adopts LoRa remote modem for ultra-long-range spread spectrum communication with high interference immunity and low power consumption. With 's patented LoRa modulation technology, the SX1262 has a high sensitivity of more than -129dBm and a power output of +22dBm, with a long transmission distance and high reliability. At the same time, compared with traditional modulation technology, LoRa modulation technology also has obvious advantages in terms of anti-blocking and selection, solving the problem of traditional design solutions can not take into account the distance, anti-blocking, and selection at the same time. The LoRa modulation technology also has significant advantages in terms of anti-blocking and selection compared to traditional modulation technology, solving the problem of traditional design solutions that can not simultaneously take into account the distance, interference, and power consumption. It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers. HT-RA62 is compatible with the following open-source projects: for Disaster Radio for Meshtastic for Tiny GS Color: Black & Silver Material: PCB+Metal Package Contents: 3 * HT-RA62 LoRa Series Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
