UM220-III N

BDS/GPS Dual-System Dual-Antenna High Precision Heading Board

• Brief Introduction

  UM220-III N is a BDS/GPS dual-system module designed for automotive applications, handheld devices, and balloon sounding.
  UM220-III N is the third generation UM220 series module, based on Unicore Low power GNSS SoC- HumbirdTM,and is by far the smallest BDS/GPS module in the market. It is most suitable for large volume BDS applications requiring small size and low power consumption.

• Product Characteristics

  • Small size and light in weight
  • Ultra-low power (120mW)
  • In support of the single system independent positioning and multi-system interoperation
  • BDS/GPS in single chip, able to send NMEA data without Auxiliary CPU
  • SMD surface-mount technology makes it easy for users production.
