The LR9101 GPS module is a high sensitivity, low power GPS module that supports NMEA, SIRF binary data output.
The LR9101 is a compact surface‑mount GPS receiver designed for OEM integration in devices such as PDAs, handhelds, and fleet‑management units. It is based on the SiRFStarIII architecture and offers high sensitivity, low power consumption, and RoHS‑compliant construction.
The document lists the module's electrical interface (TTL serial, NMEA‑0183/SiRF binary), mechanical dimensions, environmental limits, and performance figures such as position accuracy, acquisition times, and dynamic constraints, helping designers evaluate suitability for their applications.
