LTE GPS Tracker with Voice & SOS
A personal safety tracker that fits LTE cellular, GNSS, Bluetooth LE, two way voice, and an SOS button into a 52 × 38 mm board, with motion and fall detection, a multi rail power system for long battery life, and careful RF and grounding work to make three radios and a mixed signal audio path coexist in almost no space. Delivered as the full hardware cycle in Altium Designer, from system architecture and schematic through multilayer PCB layout, component selection, and the complete fabrication and assembly package.
