We’ve been busy the last month, hence the long silence on this blog. Still, we did make a lot of progress on several fronts. I was mostly occupied with this prototype LoRaX board. I’ve programmed the Murata chip on it to send periodic Lora messages and enter a deep sleep mode in between messages.
This RN2483 based LoRaWAN board was designed and built by eTh0maz Electronics. It has performed beyond our expectations. He sent it to us on the third of February – running on three AAA batteries. We could track its course through the country – using the KPN LoRa network – before it arrived here. It’s kept steadily sending messages and we do not expect it to stop any time soon.

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?
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.
