Description Atomic GPS Base v2.0 is a compact GPS and GNSS positioning base for Atom series hosts. It integrates an ATGM336H-6N-74 module with the AT6668 positioning chip, a MAX2659 low-noise amplifier, and a ceramic antenna to provide accurate satellite positioning for embedded projects. The module outputs NMEA0183 data and supports multi-frequency, multi-mode GNSS reception across GPS, QZSS, BDS, GALILEO, and GLONASS systems. With 50 channels, strong anti-interference capability, and positioning accuracy under 1.5m, it is suitable for both multi-system joint positioning and single-system independent positioning. For vehicle navigation, IoT location devices, outdoor positioning, industrial automation, robot positioning, and drone tracking, Atomic GPS Base v2.0 provides a compact low-power path to reliable satellite data while staying compatible with Arduino IDE, UiFlow1, and UiFlow2 development workflows. Features GNSS base design: positioning base for Atom series hosts. Multi-system GNSS: supports GPS, QZSS, BDS, GALILEO, and GLONASS reception.
