Help with Low Power Lora Node PCB

[BoRRoZ]

I suggest study the CH2I node a bit too, same components … very low power !

Full Arduino Mini LoraWAN below 1uA Sleep Mode

Hi Guys, I’d like to introduce my new demo node, no wire, just battery powered, Arduino Mini 3.3V 8Mhz. I created a demo for a customer with a fully Temperature Humidity sensor (I2C SI7021) with Battery Level Monitor, and here it is.

So I decided to test some with battery and my old ULPNode Power Efficient Library (not released yet but soon) but trust me this lib…
