GNSS module U70

Introduction
The U70 is an RX/TX datalink module covering 410–470 MHz and supporting LoRa (CSS) modulation. Its SMD package and compact size make it suitable for GNSS-related integrations, telemetry and low-power long-range data links.

Key Features

• LoRa (CSS) modulation for long range and low power consumption
• Half-duplex RX/TX operation
• Adjustable frequency range: 410–470 MHz
• Surface-mounted design, compact 30×30×3 mm footprint
• 12.5 kHz channel spacing

Applications
Ideal for GNSS augmentation and RTK correction links, UAV telemetry, remote sensors and asset tracking where compact form factor, low power and reliable long-range communication are required.
