Description
Overview
GAOTek High-Performance LoRa Wireless Module for Long-Distance Communication is a 433MHz,1W industrial-grade wireless data transmission unit with high stability. The DTU’s core module uses SX1278 main chip, Lora spread spectrum transmission, RS232/485 level output.
Features
- High-speed stability
- Lora spread spectrum
- Strong universality
- Low power consumption
- Long range
