Easy/Newbie PCB for MySensors

I'm not profi, is my logic correct?
general, not PBC related
I could power the mini 5V with 9V and mini's regulator converts it to 5V.
Mini could give power to radio by 5->3.3 regulator.
I could measure the voltage without booster, but the booster is good to use the battery until it is possible ? -

You will have power as long as the battery is between aprox. 6 and 9 v (minis voltage converter specs), below that it will die.

I have ordered some boards and i am looking forward to play with them.
I tried soldering some part and a nano on a soldering board but apparently my soldering skills and patience isn't what it used to be in the past.
@sundberg84 it looks good. -

I do have some questions :smiley:
I think i got it a bit. When i use a 3,3V mini then i do not need the 3,3V regulator and it is powered with a battery. If i use a 5V mini then i need the regulator. Is this correct?
Do i need the booster if batteries are used?
How about the RAW option? How does it go to 5V? i need the regulator to go to 3,3V so how do i loose the 6-12V :smiley:

Correct!! You need to add the jumper to BAT if you go with 3.3 and battery or REG if you go with 5v and voltage regulator.
Do i need the booster if batteries are used?
No, you can bypass it with a jumper/wire - but it will give you alot of extra. Without the booster the arduino 3.3v will die somewhere between 2.8 and 3 volts, with booster you can go down to 1.9v.

There is a voltage regulater on board the pro mini that handels from 6-12v (be cautious using 12 v, 9v is max i recommend on clones). This will convert your RAW to 5v and provide the board with this. Then the external regulator will go from 5 to radio 3.3v.

Ok, very clear.
So now i have a new question, i want to use a solar panel and a battery but this will go above the 3.7V when there is light and the battery pack is 3.7V so i must use the raw connection.
I also want to measure the battery and i think this needs PWR :smiley:Can i do this?
I want to build the solar powered mini weather station:

Thanks already.

@tlpeter You can use raw for 3.7V and make it down to 3.3 with the internal voltage regulator onboard the arduino, but you can not connect anything to PWR then because this will allready be 3.3V! The internal voltage regulator vill output 3.3v to the PCB from the arduino.
However, I think you can connect the battery directly to the battery measurment on the board as long as you use the same ground for both. You will need to make some new calculations (most are based on 2xAA = 3.0V) for your battery.

I didn't use your board in this case (the weather station) but i will do in the future.
I did connect the battery to the raw pin and it is working fine.
Funny, a solar panel with a battery powering the pro mini with DHT22 and BMP180.
For now i will keep it simple but later on i want a rain gauge and windmeter too.
Rain sensor is on a different Nano as this needs to be powered all the time.
It will control my sunscreen later on. -
This board looks great! Definitely going to order some.
Just getting started with MySensors. Waiting for over 20 orders from eBay with stuff. Should be fun!
Already running Domoticz (Pi 2) with RFXtrx433, 1-wire and z-wave. Going to build a serial gateway for direct connection to the Pi.My last name before I married (now divorced) was Sundberg btw. Could have had Sundberg82 as nickname. ;)

@NiklasO - Thanks! I hope it will suite you well!
The wait is a pain, but well worth it in the end. Sounds like got alof going already!Hehe, we can create a forum group - "sundberg dreamteam!" ;)

Recived my boards today and I love them, I ordered the white ones and they are looking really great
Thanks @sundberg84 !

hehe yeah, just need to change my last name back to my original one but I don't know if my kids likes that idea. ;)
Where do you get your x to 3.3v boost converter? Found some on eBay but they are quite expensive if comparing to x to 5v versions.

@NiklasO - they are quite expencive yes, but i order the ones in the mysensors store

Has anyone tried one of these boosters:
- They are sometimes much cheaper than the 3.3v ones
- Since they are adjustable, I would think you could optimize the output voltage for maximum battery.
I'm not sure, is there a problem using them with the PCB boards? I imagine the input and output ground would have to be connected together.
Thanks!

@ileneken3 - sorry never tried them.
The footprint looks different from the PCB so you need to connect this with wires to the PCB.Controller: Proxmox VM - Home Assistant

The footprint looks different from the PCB so you need to connect this with wires to the PCB.I took a chance and tried these boosters. After adjusting the pot to boost to 3.3V, and using wires to connect, they seem to work the same as the "recommended" ones. I am hoping they produce less noise for the radio - I seem to have trouble with that, even with adding the capacitors. (Maybe my radios are not good).
Another experiment - boosting them to just over the 2.8V fuse limit. I would think that would be more energy efficient.
