EVA-7M - Cost effective compact u-blox 7 GNSS module

Measuring just 7mm x 7mm x 1.1mm, the EVA-7M 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 u-blox EVA-7M standalone GNSS module features the reliable performance of the u-blox 7 positioning engine. It is able to track GPS (QZSS), GLONASS and SBAS satellite signals. The EVA-7M delivers high sensitivity and achieves minimal acquisition time, all in the ultra compact 7 x 7 mm EVA form factor.

The EVA-7M 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-7M has been  especially developed to ease design while limiting near field interferences since RF and digital domains are kept separated. EVA-7M uses a crystal oscillator to lower system costs. Like other u-blox GNSS modules, the EVA-7M uses components selected for functional reliability in the field as well as over the full operating temperature range.

Key Features:

  • Industry's smallest standalone GNSS module
  • Lowest system cost in the industry
  • Minimal power consumption
  • Simple integration with u-blox wireless modules
  • Eases design and manufacturing
  • No host integration or external components needed
