High Precision GPS Module with TTL Level, 110Hz Update Rate and Flash Memory - VK2828U7G5LF

Welcome to our shop! This GPS module is equipped with a standard 25 x 25 x 4MM high sensitivity GPS antenna, ensuring good positioning effect. It adopts UART/TTL level, with optional 232 interface, providing stable performance and high transmission. The module uses KDS 0.5 PPM high accuracy TCXO, built-in SQI flash memory, and built-in RTC crystal and Picofarads capacitor, ensuring faster heat root. It also has a built-in LNA, low noise amplifier 1-10Hz, creating a quiet working environment. This module supports online AssistNow and offline AssistNow, GPS, GLONASS, GALILEO, SBAS (WAAS, EGNOS, MSAS, GAGAN) hybrid engines for better performance.
