@jlaraujo, I'm searching a more reliable way to connect the RFM69HW module to the Pro Mini.
I'm aware that this project is already 2 years old.
You didn't answer to the question of user @salfare, maybe you didn't see his question?
I'm very limited in height for what I'm trying to build, what is the height of the two stacked?
Hey @ejlane! Many thanks. I didn't see your message from a while ago (don't seem to get these in my email). I just ordered the PCB at JLCPCB.com. Worked great! Thanks again. Looking forward to building this gateway.
@Joost I measured the current with another, even older, analog type of multimeter, a type where you need to read the needle using an integrated mirror
It is measuring approximately the same deep sleep current: 141µA
Maybe the two multimeters are not correct, but they all give the same order of magnitude.
Next weekend, I will redo a measuring:
a new Pro Mini + sketch deepsleep from lowpowerlab
the same Pro Mini without the power led + sketch deepsleep from lowpowerlab
the same Pro Mini without the power led and regulator + sketch deepsleep from lowpowerlab
To be continued
PS: @Joost, did you see my message about your breakout pcb to be able to order it via openhardware.io?
