About the Football gnss tracker PCB

Football gnss tracker is an open source Nordic nRF PCB design by Bouhafs-Aek, published on GitHub. It is a 4-layer board measuring 42 × 72 mm, with 44 components from 27 distinct parts.

Its main chip is the MDBT50Q-1MV2, from the Nordic nRF family. Other key parts include the NEO-M9N-00B, ISM330DHCX, MCP73831-2-OT, AP2112K-3.3 and USBLC6-2SC6. By type, the board carries 14 capacitors, 12 resistors, 6 ICs, 3 connectors, 3 diodes and 1 transistor.

It belongs with the rf & radio, iot & wireless and power & battery designs in this gallery.

From the project

A wearable player tracker for football: a pod worn between the shoulder blades in a vest, logging position, speed and inertial data for training analysis. In the paper's terms it is an EPTS, an Electronic Performance and Tracking System.

Their prototype (a Maduino Zero A9G with a GPS-only receiver logging at 1 Hz) reached 0.21 m mean error after outlier removal and an 11-sample moving average. They list the limits themselves: 1 Hz misses sprints and changes of direction, GPS-only suffers multipath, there is no IMU, and satellite count and DOP were never logged. Their conclusion asks for…

Football gnss tracker: common questions

What microcontroller does the Football gnss tracker use?

The Football gnss tracker is built around the MDBT50Q-1MV2, from the Nordic nRF family.

How big is the Football gnss tracker PCB?

The Football gnss tracker measures 42 × 72 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Football gnss tracker?

44 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Football gnss tracker design files?

From the Bouhafs-Aek/football-gnss-tracker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Football gnss tracker design in my own project?

The repository has no license, so all rights stay with Bouhafs-Aek. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Football gnss tracker without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
