The M5 Stack Atomic GPS Base V2.0 uses the AT6668 chip with MAX2659 amplifier and ceramic antenna, supporting GPS, BD2, BD3, GLONASS, GALILEO, and QZSS reception. It outputs via NMEA0183 4.1 protocol, offering high accuracy and strong anti-interference positioning.
M5Stack Atomic GPS Base V2.0is a GPS positioning module based on the Atom series of hosts. It integrates a high-performance AT6668 chip with a built-in MAX2659 low-noise amplifier and ceramic antenna, providing accurate and reliable satellite positioning services.
It uses the NMEA0183 4.1 protocol for output and supports multi-frequency and multi-mode GNSS signal reception. It can receive signals from multiple satellite navigation systems such as GPS, BD2, BD3, GLONASS, GALILEO, and QZSS. It can be widely used in applications such as high-precision multi-system joint positioning and single-system independent positioning. It has strong anti-interference ability and high positioning accuracy, making it suitable for vehicle positioning and navigation, IoT positioning devices, industrial automation and robot positioning, and drone positioning.
