SparkFun GNSS Flex pHAT - DAN-F10N

Equip your Raspberry Pi projects with precise dual-band GNSS positioning using the SparkFun GNSS Flex pHAT. This development platform combines a versatile GNSS Flex pHAT carrier board with the reliable DAN-F10N module, offering an affordable and easy-to-integrate solution for any single-board computer with a 40-pin header. The GNSS Flex pHAT bridges your SBC and the modular SparkPNT ecosystem, mounting securely via an extended 40-pin header and connecting to the GNSS module using standardized 2x10-pin headers for easy module swaps.

Compatible with a range of single-board computers, the 40-pin header connects directly to Raspberry Pi, NVIDIA Jetson Orin Nano, Google Coral, and other compatible devices. A USB-C port provides an alternative data interface, while a microSD card slot is perfect for logging position, velocity, and time data. Complete with mounting hardware, including standoffs, screws, and an extended header, it ensures a clean and stable setup.

At the core of this module is the cost-effective u-blox DAN-F10N, designed to perform exceptionally in challenging environments like dense urban areas. Utilizing dual-band L1/L5 GNSS technology and a sophisticated multipath mitigation engine, it achieves meter-level accuracy. Its robust RF architecture, featuring a SAW-LNA-SAW filter chain and an additional notch filter for the LTE B13 band, offers outstanding out-of-band interference rejection, ensuring clean signal reception even near cellular modems.

The DAN-F10N includes a high-performance, integrated 20mm x 20mm x 8mm dual-band patch antenna. This Right-Hand Circularly Polarized (RHCP) antenna provides a wide beamwidth, allowing flexibility in device orientation without sacrificing performance. For extended range, an onboard switch enables easy connection to an external dual-band antenna, optimizing signal reception for specific applications.

Comprehensive software support ensures a quick start, with full compatibility with the u-blox u-center 2 GNSS software for real-time performance analysis, configuration, and data logging. Fast acquisition is facilitated by AssistNow Online, Offline, and Autonomous A-GNSS services, significantly reducing time-to-first-fix. Standard protocols, including the industry-standard NMEA 4.11 and the powerful UBX binary protocol, offer direct module interface for advanced control.
