UM220-IV NL

UM220-IV NL

Industrial Grade Multi-GNSS Navigation and Positioning Module

UM220-IV NL is a multi-system GNSS module based on Unicore's proprietary low power high performance SoC - UFirebird. It supports AGNSS function, which improves the positioning speed with the help of assisted data transmitted through network. The module also supports high precision solution on the user's hardware platform to improve positioning accuracy. UM220-IV NL is of compact size and adopts SMT pad, supporting standard pick-and-place and fully automated integration of reflow soldering, particularly suitable for low cost and low power consumption applications.
