@Nca78
on the proto board, it is nrf24 low power, smd version, actually. Works ok here but for better perf, i'm planning to use the PA/LNA through hole version with sma connector.
So far (but not digged a lot) i've only seen PA smd modules with ipex (but would be better if i could fit sma) or chip antenna (lol). Are you thinking to an other reference, or have a favorite module??
@bilbolodz not from my side anywhere soon... Just too busy...
Hi,
I'm actually adding "last minute" features (so the delay) without increasing board size.
Features like:
See you soon with good news i hope 
@mfalkvidd - thanks. Have to recheck... maybe 2mA was during loop and there was a peak up which I didnt notice when transmitting. * feeling a bit more confident *
@ileneken3
I'm having some fun with @d00616 work And it's working fine so far (thx again).
I have not tested battery performance for the moment.. NRF52 is capable of very low power but i think the low power is not enabled yet in the porting, it's explained in the project prez if i remember
Regarding range, sure NRF52 is an improved chip compared to NRF24 for instance, but the most important part is the antenna. That's the case for all mcu though. Take a long range capable mcu and a bad antenna choice, or a bad antenna design (bad gnd plane, bad clearance for antenna etc) and you'll never get the long range (example: miniaturized chip antenna, or some pcb antennas too).
For the simplest devices to buy, no idea as i'm making custom boards.
@sundberg84 no. It should consume 16-45 mA. See datasheet.
To answer my own question I found this thread where he gets the exact same sleep current as I do (5.2uA). Still wondering about the high send current though.
Is 2.0mA a normal power consumption for RFM69W when its transmitting? Will investigate but all input appreciated...
@NeverDie for a theoretical maximum, check out https://physics.stackexchange.com/questions/880/how-many-photons-per-second-is-one-lumen
A perfect led would convert all the electrical energy into photons of your chosen wavelength(s). Seems like leds are only able to convert about 10% though.
What signal voltage do you need to measure? Octocouplers need to be choosen accordingly
So I have made the adjustment for low power/battery mode (removed the LED, voltage regulator and sleeping most of the time).
Im having a hard time to trust my Multimeter at this point... showing 5.1uA in sleep() mode while sending shows almost 2mA! This cant be right???
At the moment im all out of boosters... I was sure I had more so I didnt order.
What I have done now is uploaded a sketch sleeping 15min, running the vcc check (since I dont have a booster) and reporting it back to me. Lets see what happens...
