GPS logger sa SD karticom je projekt dimenzija 75mm x 50mm x 45mm. Nije baš mali ali je opensource. U mogućnosti je da snima lokacije 40 sati bez prestanka a u standby modu može biti 4 mjeseca zbog male potrošnje struje. Podaci se snimaju na SD karticu u blokovima od po 512 bajta. Na kartici nema fajl sistema tako da čitanje podataka sa kartice treba raditi blok-po-blok (jedan blok iznosi 512 bajta). Nakon iščitavanja podataka, njih je moguće predstaviti na stranici OpenStreetMap koja za divno čudo ima i našu državu u bazi.
