The state-of-the-art 66 channels MediaTek MT3329 GPS Engine
High sensitivity: Up to -165dBm tracking, superior urban performance
USB/UART Interface
Build-in patch antenna for optimal sensitivity
DGPS(WAAS, EGNOS, MSAS) support (optional by firmware)
Maximum update rate : up to 10Hz (optional by firmware)
RoHS compliant

Note that the new MediaTek has custom and exclusive "DIYDrones" firmware that allows the unit to output an efficient and very compressed binary protocol. You can still change between NMEA and Binary protocol with standard MTK messages, and switch the refresh rate between 1hz to 10hz, or set any standard serial baud rate (by default is set to 38400 bps and custom binary protocol).

Features:
-Based on MediaTek Single Chip Architecture.
-Dimension：16mm x 16mm x 6mm
-L1 Frequency, C/A code, 66 channels
-High Sensitivity：Up to -165dBm tracking, superior urban performances
-Position Accuracy：< 3m CEP (50%) without SA (horizontal)
-Cold Start is under 35 seconds (Typical)
-Warm Start is under 34 seconds (Typical)
-Hot Start is under 1 second (Typical)
-Low Power Consumption：48mA @ acquisition, 37mA @ tracking
-Low shut-down current consumption：15uA, typical
-DGPS(WAAS, EGNOS, MSAS) support (optional by firmware)
-USB/UART Interface
