On the Shoulders of Giants

An older ITalks LoRa tracker next to a two euro coin. The device is huge compared to the coin. This illustrates the recent progress in the miniaturisation of tracker hardware.We’ve had this LoRa tracker lying around. We used it to test the KPN LoRa network coverage as it unfolded throughout the country. This thing is huge compared to more recent tracking solutions, and it’s only a few months older. Will this trend of miniaturisation continue?

New hardware ­– It’s so tiny!

Size comparison between a Murata LoRa chip and a two euro coin. The tiny hardware is much smaller than the coin.We’ve gotten our hands on some tiny hardware samples from Murata for our LoRa project. These are about a fifth of the size of the previous chips we used. With this tiny hardware it might be possible to create a tracker that’s smaller than a two euro coin – excluding the battery. With a stacked coin cell battery the completed device might actually look like a fat coin. For now we need to get these chips soldered onto a test board.
