The EVA-M8M GNSS modules feature the exceptional performance of the u-blox M8 positioning engine (GPS, GLONASS, BeiDou, QZSS and SBAS). The EVA-M8M series modules delivers high sensitivity and minimal acquisition times in the ultra compact EVA form factor.
 
The EVA-M8M series 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-M8M is especially designed to ease the customer’s design and limit near field interferences since RF and digital domains are kept separated.
 
The EVA-M8M series uses a crystal oscillator for lower system costs. Like other u-blox GNSS modules, the EVA-M8M series uses components selected for functioning reliably in the field over the full operating temperature range.
