sounds like nice projects, but from my experience the maintenance costs are much higher than the pure hardware costs. In addition, certification costs shouldnt be underestimated, especially for radios - so any m2 / minipcie solution for lower volumes is much cheaper.
Lilygo [1] got quite impressive low cost devices... but there its the same, limited certification and not sure about industrial temperature/humidity capabilities. [1] https://www.lilygo.cc/products/t-sim7600 |
