WhiteCat ESP32 N1
I do not do reviews usually, but I sometimes do exceptions. In this case, it's worth doing it, due to 4 main reasons:
It's a software & hardware open source project It's local (local to me, that's it) It's led by two good friends It's related to LoRa and The Things Network It's awesome! OK, they were actually 5 reasons, but the last one just slipped in.
The WhiteCat ESP32 N1 Board The WhiteCat ESP32 N1 Board is a green board in a long-ish form factor, longer than the LoPy or the Chinese ESP32-based LoRa boards....
M5Stack node for The Things Network
I have a couple of IKEA-like boxes in my home office labeled “Inbox”. They are full of stuff I buy and store waiting for some free time to spend on them. From time to time I pick one of the boxes and take a look at its contents. They are actually full of “wow” stuff. I would buy again most of the things there but at the same time I fear I'm just collecting stuff that will become junk....
Arduino MKR WAN 1300
I've been testing quite a few LoRaWan nodes lately for TheThingsNetwork.cat, some based on HopeRF RFM95W (over AVR, ESP8266, ESP32,…) others using Microchip's RN2483 (an old friend of mine). I have a RAK811 waiting in the INBOX but the last one I've been playing with has been the new Arduino MKRWAN 1300 (so new there is no product page yet) and I liked it, quite a lot.
The device is one of the MKR series Arduino is pushing forward....
Low power in LoRaWan world - Meet the RN2483
I'm working on a project were I have to build a network of battery powered sensors over a territory the size of a small town.The sensors will monitor power consumption, temperature and humidity in energy poor households. Often the families in that situation can't afford an internet connection at home so WiFi is out of question. GPRS would be an option but lately other radio technologies have come to my interest....
