SparkFun GNSS Flex pHAT - DAN-F10N

The DAN-F10N GNSS Flex pHAT brings meter-accurate satellite positioning to your Raspberry Pi, with dual-band receivers that work in urban canyons where simpler systems fail.

Equip your Raspberry Pi projects with meter-level, dual-band GNSS positioning using the SparkFun DAN-F10N GNSS Flex pHAT. This development platform combines our versatile GNSS Flex pHAT carrier board with the reliable DAN-F10N GNSS Flex Module, providing an affordable and easy-to-integrate solution for any single-board computer with a 40-pin header. The GNSS Flex pHAT acts as the bridge between your Raspberry Pi and the modular SparkPNT ecosystem. It mounts securely via an extended 40-pin header and connects to the included GNSS module using standardized 2x10-pin headers, making it simple to swap modules for repairs or future upgrades.

* Raspberry Pi Connectivity: Standard 40-pin GPIO header for a direct, secure connection.

* USB-C Port: Provides an alternative data interface to the GNSS module.

* MicroSD Card Slot: Perfect for data logging position, velocity, and time data.

* Mounting Hardware Included: Comes with the necessary standoffs, screws, and an extended header for a clean, stable setup.

Economical Urban Performance At the heart of this module is the affordable u-blox DAN-F10N, engineered to excel where other receivers struggle. By harnessing dual-band L1/L5 GNSS technology and a sophisticated multipath mitigation engine, it delivers meter-level accuracy in challenging environments like dense urban canyons. Additionally, its robust RF architecture features a SAW-LNA-SAW filter chain and an additional notch filter for the LTE B13 band. This design provides exceptional out-of-band interference rejection, ensuring clean signal reception even when operating near cellular modems. Flexible Antenna Options The DAN-F10N includes a high-performance, integrated 20mm x 20mm x 8mm dual-band patch antenna. This Right-Hand Circularly Polarized (RHCP) antenna offers a wide beamwidth, giving you flexibility in device orientation without sacrificing performance. Need even more range? An onboard switch allows you to easily connect an external dual-band antenna to maximize signal reception for your specific application. Powerful Software & Connectivity Get up and running quickly with comprehensive software support. The DAN-F10N is fully compatible with the u-blox u-center 2 GNSS software, a tried and tested tool for real-time performance analysis, configuration, and data logging.

* Fast Acquisition: Utilize AssistNow Online, Offline, and Autonomous A-GNSS services for significantly reduced time-to-first-fix.

* Standard Protocols: Interface directly with the module using the industry-standard NMEA 4.11 or the powerful UBX binary protocol for advanced control.

Users have the option to connect an external GNSS antenna to their GNSS receiver.

* The GNSS Flex module has a U.FL connector for an external antenna.

This product requires a Raspberry Pi (or similar single-board computer). By default, we use the Raspberry Pi's primary serial bus (i.e. TX: GPIO14/Pin 8; RX: GPIO15/Pin 9) to communicate with the GNSS receiver on our SparkPNT GNSS Flex modules.
