1. A wearable device for coupling to sports headwear that is to be worn on a head of a user, the wearable device comprising:
a housing; and
a printed circuit board (PCB) housed in the housing, the PCB comprising:
alternating layers of core material substrate and prepreg material substrate in a stacked arrangement, wherein each of a top layer and a bottom layer of the stacked arrangement is a core material substrate;
a conducting material layer on each side of each of the core material substrates, a lower conducting layer of the conducting material layers being at a first side of the PCB, an upper conducting layer of the conducting material layers being at a second side of the PCB opposite to the first side, and a plurality of internal conducting layers of the conducting material layers being between the upper and lower conducting layers;
a plurality of electronic components arranged on the upper conducting layer, the electronic components comprising an accelerometer configured to detect an acceleration change experienced by the wearable device;
a short-range wireless antenna arranged on the lower conducting layer, the short-range wireless antenna being for transmitting data indicative of the acceleration change detected by the accelerometer off-board the wearable device;
a satellite navigation antenna arranged on the lower conducting layer adjacent to the short-range wireless antenna, the satellite navigation antenna being for tracking movement of the wearable device; and
a plurality of via holes each providing electrical connection between the conducting material layers;
wherein a plurality of the internal conducting layers are arranged using the via holes as ground planes for the short-range wireless antenna and the satellite navigation antenna.
