Hi @tbowmo, do you mind to explain a bit about the design? I'm interested with your design.
I will use these steps for removing voltage regulator, http://goo.gl/CsZaNg
So the design will be battery > external step up regulator (http://goo.gl/PFt99R - to stabilize 3.3v) > vcc pin ?
with these then I can use my first post design?
Thanks
Hi @Siddharth-Velappan
The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time.
Do you mind explaining your setup a bit more? I would love to do something similar but I do not know where to get started with the PIC microcontroller!
@NeverDie Perhaps but the design is a bit too simple and unoriginal. I'd have to clean up the files a bit and I haven't touched Eagle since I made this board several years ago.

I also on my last work removed the LG33, it's faster
Well this most likely have been provided as info, but else it's here:
Remember to burn new OPTIBOOT 8MHz into the Arduino Pro Mini
and then I also use avrdude with a usbtinyISP to set the fuse to not check battery voltage monitoring, this is done after I have flashed this with Arduino IDE
avrdude -c usbtiny -p m328p -U efuse:w:0x07:m```
