true… I’ll try a few different usb-serial modules first 
Absolutely, got some 
and of course I’ll have to ask… where can I find it , lex’s code ?
for battery level I have CH2I lib so no resister divider
14399 nA … WOW… I’m jealous 
I think he maybe is using this one as described in this post :
@pe1mew, please correct me if i’m wrong.

Last but not least, got 1mA sleep mode, but better after putting flash to sleep

I need to write a small sketch just to test sleep mode for this modules with RFM95 modules
Q : maybe stupid, but if we leave the protection diode on the board and use a 3v6 battery ?
will the voltage drop enough to ‘protect’ the mcu/rfm95
A: You will loose 0.6 Volt of “use”. When the battery voltage drops the node will stop operating earlier than without.
BTW: I have abused RFM95 many times using 5V and they never failed me. (lucky me)
yes… but with the BOD set at 1.8 ?
Absolutely not stupid, that’s the deal, what I’m doing first is to think how board will be powered
- Lipo : leave protect diode (to protect if on board charger and connected with USB) and regulator
- 3.6V battery remove LDO and Diode
so the first if “how the board will be powered”

amazing, same for me, latest was even with RN2483 module
you two should buy a lottery ticket today !

I fried LoRaDuino yesterday, putting FTDI reversed and with 5V, no smoke nor either, but no more upload
Removed diode and LDO
In my Lora-Radio-Node
Buzzer and moisture-oultet shall be added later.

ok ordered some… will take the risk of frying
Nice, I need to do that, You could even let the diode, wiring 3V3 to VBAT with dupond on connector

I’m using this one works fine
