Ordering information 
  • With GPS module Gmm-u2p : NLC-CRN-LITE-U2P
  • With GNSS module Gmm-g3 : NLC-CRN-LITE-G3
(1) GNSS antenna is required to track GPS+GLONASS constellation.

Important Note :

Gmm-u2P and Gmm-g3 receivers do not have an internal Flash memory to store configuration.
We can do a customized firmware to your application with required NMEA messages, baud rate, update rate….
For example you need only GGA, RMC, ZDA messages at 5Hz 115200 baud, we preload the module in factory with your customized firmware with your default configuration.
You do not have to send any packets to manage GPS/GNSS module configuration, your configuration is preloaded!

Mounting flanges are not included by default. If required please contact us. Picture above includes flange.
