{"title":"GNSS Timing Breakout - ZED-F9T-20B (Qwiic)","handle":"sparkfun-gnss-timing-breakout-zed-f9t-20b-qwiic","url":"/products/sparkfun-gnss-timing-breakout-zed-f9t-20b-qwiic","description":"Built around the u-blox ZED-F9T-20B receiver, this breakout is made for projects where precise time matters as much as location. Under clear skies it can provide five nanoseconds of timing accuracy without requiring external GNSS correction data, making it suitable for 5G IoT networks, distributed sensor grids and high-precision NTP servers.The module supports multi-band reception across major constellations, helping maintain timing stability even if one or more constellations drop out. It also includes native Galileo OSNMA support to help verify the authenticity of GNSS data and protect against spoofing.For connectivity, the board includes USB-C for primary power and communication, two Qwiic connectors for solder-free I2C integration, three SMA connectors and PTH breakouts for advanced access to the ZED-F9T-20B pinout. An onboard rechargeable backup battery powers the internal RTC to reduce Time-To-First-Fix from a cold start to a hot start.Documentation and resources provided by SparkFun include the schematic, Eagle files, board dimensions, hookup guide, ZED-F9T-20B documents, u-center software resources, Qwiic information, Arduino Library - v3 and the GitHub hardware repo.Features:Concurrent reception: GPS / QZSS, Galileo, BeiDou, NavIC constellationsMulti-band reception: Receives L1/L2/L5, E1/E5, and B1/B2 bandsGPS / QZSS bands: L1C/A, L2C, L5Galileo bands: E1B/C, E5b, E5aBeiDou bands: B1I, B1C, B2a, B2ISecurity: Built-in security, including Galileo OSNMASMA Connectors: Includes three SMA connectors (one for the antenna and two dedicated for timing pulse signals), allowing for secure, low-loss connections to external equipment.USB-C & Qwiic: Features a modern USB-C connector for primary power and communication, plus two Qwiic connectors for easy, solder-free I2C integration with the rest of your system.Full Access: For advanced users, a host of PTH pins are broken out, enabling direct access to most of the ZED-F9T-20B's pinout.Fast acquisition: Onboard rechargeable backup battery powers the module's internal Real Time Clock (RTC), reducing Time-To-First-Fix from a cold start (~24 seconds) to a hot start (~2 seconds).Specifications:Voltage: 5V or 3.3V (all logic is 3.3V)Current: 68mA - 130mA (varies depending on operating conditions and constellations)Fix Acquisition: ~24s (Cold) / 2s (Hot)Time Pulse Signal Accuracy - Absolute Timing Mode: 5nsTime Pulse Signal Accuracy - Differential Timing Mode (with correction data): 2.5nsTime Pulse Signal Frequency: 0.25Hz to 25MHzTime Pulse Signal Jitter: ±4nsHorizontal Position Accuracy: 2.0mMax Altitude: 80km (49.7 miles)Max Velocity: 500m.s (118mph)I2C Address: 0x42Qwiic Connectors: 2x Qwiic ConnectorsA strong choice for timing labs, network synchronisation, GNSS development and embedded systems that need accurate time pulse outputs with Qwiic-friendly integration.","vendor":"SparkFun","product_type":"GNSS Timing Breakout","in_stock":true,"options":[],"variants":[{"id":15866,"title":"Default Title","sku":"SF-GPS-30975","mpn":"GPS-30975","price":658.2,"on_sale":false,"in_stock":true,"available_quantity":9}]}
