Introduction

ER-DF-04 Small Size High Precision Direction Finding Board

It can receive GNSS signals from full-frequency points of the whole constellation and fully support the reception of BDS-3 satellite signals.The new swan anti-interference technology is adopted to improve the performance under complex environment.The board card adopts the small size design of 28pin and is compatible with the mainstream direction finding board. It can be used in precision agriculture, mechanical control, navigation and other high-precision applications.

Features
