## Description

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](https://www.u-blox.com/en/product/u-center), 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.
 
This product requires a Raspberry Pi *(or similar single-board computer)*. Users can find [Raspberry Pi](https://www.sparkfun.com/development-boards/single-board-computers/raspberry-pi/raspberry-pi-boards.html) and [Nvidia](https://www.sparkfun.com/development-boards/single-board-computers/nvidia.html) single-board computers in our catalog.

**Note:**

- The GPS `L5` signals are currently, considered as *"pre-operational"* and not utilized by default in navigation solutions. However, it is possible override the receiver's configuration to evaluate the GPS `L5` signals. Please refer to the integration manual for more details.
- This is an operational limitation of the satellite/space segment and not an issue of the u-blox product.
 
- Users have the option to connect an external GNSS antenna to their GNSS receiver.
- The GNSS Flex module has an U.FL connector for external antenna.
- Users can find [GNSS Antennas](https://core-electronics.com.au/wireless/gps/antennas.html) in our catalog.
 
- By default, Sparkfun 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.
