LC29T Evaluation Board Description

Quectel LC29T (AA) is a high-precision, multi-constellation GNSS module designed to deliver reliable timing and positioning in demanding applications worldwide. It simultaneously receives and tracks the L1 frequency band from multiple GNSS constellations (GPS, BDS, GLONASS, Galileo, and QZSS). The module’s timing functionality remains available even when only a single satellite is being tracked. Internal AEC‑Q100–qualified silicon and strict manufacturing/testing control ensure consistent, high-quality performance.

  • Any GNSS-enabled equipment requiring robust interference resistance and fast acquisition

LC29T Evaluation Board (EVB) benefits

An evaluation board for the LC29T (AA) lets you integrate, test, and validate the module quickly without designing a custom PCB first. The EVB simplifies development and speeds time-to-prototype by providing breakouts, power management, antenna interfaces, and example connections/firmware. Other benefits include easier signal debugging, access to the module’s timing/PPS outputs for system integration, and reduced risk in early-stage design—helping you design faster and with greater confidence.
