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....

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.

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....

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....
