EVA-8M - Cost effective standalone GNSS SiP module

The EVA-8M is a compact GNSS module, offering high sensitivity, minimal power consumption and superior anti-spoofing and anti-jamming.

The EVA-8M standard precision GNSS module features the reliable performance of the u-blox 8 positioning engine (receiving GPS, GLONASS, QZSS and SBAS signals). The EVA-8M delivers high sensitivity in the ultra compact EVA form factor.

The EVA-8M supports advanced Power Save Modes and provides message integrity protection, geofencing, spoofing detection, and odometer functionalities and is an ideal solution for cost and space-sensitive applications. It is easy to design-in, only requiring an external GNSS antenna in most applications. The layout of the EVA-8M is especially designed to ease the customer's design and limit near field interferences, since RF and digital domains are kept separated.

EVA-8M uses a crystal oscillator for lower system costs. Like other u-blox GNSS modules, the EVA-8M uses components selected for functioning reliably in the field over the full operating temperature range.

The module combines a high level of integration capability with flexible connectivity options in a miniature package. This makes it perfectly suited for industrial and massmarket end products with strict size and cost requirements. The DDC (I²C compliant) interface provides connectivity and enables synergies with most u-blox cellular modules.

Key Features:
  • High sensitivity of -164 dBm
  • Cost‑efficient system
  • Minimal power consumption
  • Superior anti‑spoofing and anti‑jamming
  • Pin‑compatible to EVA‑7M
