Overview
Unicore UM220-IV NL is a multi-system GNSS positioning module. Based on the
low power and high performance GNSS SoC-UFirebird, the module supports GPS L1
+BDS B1 dual system joint positioning and single system standalone positioning, as
well as the QZSS signal. The module supports AGNSS, which can reduce the
positioning time with the help of assisted data service when connected to network.
UM220-IV NL is compact in size, with SMT pads, and supports fully automatic
integration of standard pick-and-place and reflow soldering, especially suitable for
low cost and low power consumption fields.
