N20A Introduction
Overview
N20A is a small, high performance and automatic assisted GNSS module. It is based on MTK high sensitivity navigation system, supporting dual-star. It is reliable and can be used steadily for 5-10 years during -40~85℃. It has tiny package and extremely low power consumption, which makes it easier to be applied to power sensitive devices.
