Beefed up pro mini with Mega2560

gohan Mod last edited by

I was wondering if this could be an option for nodes that are running low on power/memory. Does anybody know if it is too power hungry compared to a regular pro mini?

@mrussi I am also interested in using an esp32 with lora as the gateway. Did you make it work? I planning to buy, https://www.botnroll.com/en/esp/2979-esp32-wifi-bluetooth-lora-sx1278-433mhz-with-0-96-oled-display.html

@evb said in Please give me an advice for a simple sensor node: But the node will continue to work till 1.8V in a safe operating area. Yeah sure, but alkaline batteries are nearly depleted when they get to 1V, so barely worth the hassle.
