## Description

This GNSS Flex board combines a u-blox ZED-X20P all-band RTK GNSS receiver with a Feyman IM19 IMU, giving compatible carrier boards centimetre-level positioning plus compensated attitude data for demanding navigation and surveying projects.It is designed for the SparkPNT GNSS Flex ecosystem, with a swappable, pin-compatible module format for future upgrades. The carrier connection breaks out GNSS interfaces including USB, dual UARTs and I²C, plus dedicated UART connections for the IMU.The ZED-X20P navigation data is fed to the IM19 by default, allowing the IMU to output proprietary NMEA messages containing compensated position and roll, pitch and yaw. Onboard jumpers let you reconfigure that default link for your project.An external antenna and a GNSS Flex carrier board are required. You can connect an active multi-band GNSS antenna directly to the module’s U.FL connector, or use the SMA connector on a GNSS Flex pHAT carrier via a short U.FL jumper cable.Features:Swappable Flex format: Designed to be easily swappable and pin-compatible for future upgrades.RTK & PPP Ready: Supports Real-time Kinematics (RTK), PPP-RTK, and Precise Point Positioning* for ultimate flexibility.L-Band Corrections: Natively supports L-band correction services*, eliminating the need for external receivers.High Update Rate: Ensures smooth and reliable operation in high-speed robotics and vehicle control systems.Uncompromising Security: Features multi-layered defences including a Root of Trust, advanced jamming and spoofing detection, and Galileo OSNMA cryptographic authentication.Survey-Grade Accuracy: Delivers roll and pitch measurements accurate to within 0.05 degrees.Tilt Compensation: The IM19 can calculate a virtual digital level point at any tilt angle.Sensor Fusion: Offers a continuous navigation solution (Dead Reckoning) even during brief GNSS signal loss.Programmable flash memory: Supported by the ZED-X20P.Carrier phase output: Supported by the ZED-X20P.Jamming detection: Supported by the ZED-X20P.Galileo OSNMA: Supported by the ZED-X20P.Secure boot: Supported by the ZED-X20P.Specifications:Module: GNSS Flex Module - ZED-X20P and IM19GNSS module: u-blox ZED-X20P Allband, GNSS moduleGNSS constellation: GPS (USA)GNSS constellation: Galileo (EU)GNSS constellation: BDS (China)GNSS constellation: QZSS (Japan)GNSS constellation: NavIC (India)SBAS system: WAAS (USA)SBAS system: EGNOS (EU)SBAS system: BDSBAS (China)SBAS system: MSAS (Japan)SBAS system: GAGAN (India)IMU: IM19 Inertial Measurement UnitHeaders: Two 2x20-pin, 2mm-pitch female headersSocket: 40-pin socket for GNSS Flex pHAT / BreakoutPower: 3.3VPower interface: Backup powerUSB bus detect: not a power sourceUSB: USB (x1) (Read USB note)UART: UART (x4)I2C: I2C busPPS signal: PPS signal (x1)PVT signal: PVT signal (x1)RTK signal: RTK signal (x1)Event signal: Event signal (x1)U.FL connector: GNSS Antenna (Active, Multi-band)Active antenna power: 3.3V power for an active antennaDimensions: 44.0mm x 34.0mm (Approx. 1.73" x 1.34")Mounting holes: Four mounting holesMounting screw compatibility: 4-40 screw compatibleHole centers: 39.0mm x 29.0mmHeader spacing: 36.0mmUSB: ZED-X20P only (D+ and D-) (Read USB note)I2C: ZED-X20P only (SDA and SCL)Flex COM1: ZED-X20P UART1 (TX and RX only)Flex COM2: ZED-X20P UART2 (TX and RX only)PPS1: ZED-X20P TIMEPULSEPPS2: N/CEVENTA: ZED-X20P EXTINTEVENTB: N/CRTK LED: ZED-X20P RTK_STAT (Inverted)PVT LED: ZED-X20P GEO_STAT (Geofence)Supply voltage: 2.7V to 3.6VGPS support: L1C/A, L2C, L5Galileo support: E1B/C, E5a, E6BeiDou support: B1I, B1C, B2a, B3IQZSS support: L1C/A, L1C/B*, L2C, L5, L6NavIC support: L1*, L5SBAS support: L1C/AZED-X20P interface: USB (Read USB note)ZED-X20P interface: UART x2ZED-X20P interface: SPIZED-X20P interface: I2CService: AssistNowService: PointPerfectOperating temperature: -40°C to 85°CAccelerometer operating range: ±8gGyroscope operating range: ±1000°/sAccelerometer Bias: ±5mgGyroscope Bias Accuracy: ±0.2°/sRoll/Pitch: ±0.025° (1σ)Heading: ±0.25° (1σ)RTK: + 0.3mm/tilt°, with 200cm straight pole (1σ)Auto Steering Yaw: 0.25° (1σ)Initialization: ~1s*: Feature in developmentAccording to u-blox, support for Precise Point Positioning (PPP) and full L-band correction services is still under development and will be made available through a future firmware update.
