💬 Easy/Newbie PCB for MySensors

[Tommas]

Dear @dbemowsk

I bought these: https://www.ebay.com/itm/401088383355

Thank you!

@Tommas - this is the voltage regulator that the board is designed for so the markings/pinout will be right for you. If you put 5v on the PCB input and use 3.3v pro mini though, the only choise you have is to put 5v on RAW and let the onboard voltage regulator on the PCB regulate it down to 3.3v. The voltage regulator on the PCB only regulate the voltage to the radio and are meant for a 5v input on a 5v pro mini. Using raw means there is no need for the LE33.

@sundberg84 Is there any way to say if booster is a bad one or not before ordering them?
The one I ordered was the one on shoping list from aliexpress. Will try I capacitator and see if I can get a new booster from kjell&Comany tomorrow just to try. Build a setup on bread bord where I powered radio with 2 AA and got the same result. Got a fju places where I like to put some sensors with no power so realy need to get this working :). Could the radiomodules be bad to?

[gohan]

Bad quality from cheap Chinese suppliers, is always an option 😁

[sundberg84]

@keldandorin - could be a weak clone radio yes.
Just to get your hopes up, I got booster driven nodes all around the place with Nrf24l01+ radio and they works great!
I change battery every 1-1.5 years but as I said, the experience is that the radio - booster needs a good teamwork :)

[keldandorin]

@sundberg84 Sounds good, Thats what I'm looking for. Have never worked with tinkers like this befor so everything is new. But this place is great thx for taking time.

Sorry, I'm a bit slow and maybe a little off-topic: A quicky:

Can I read somewhere how payment is done when ordering from openhardware.io? On the start page for openhardware.io there is no clue. I've also tried to search this section (easy-newbie-pcb-for-mysensors) for "payment".

Yes, I've read that the "order" is more like a forward of orderinformation to the supplier, but do I really need to order first and after that ask what payment solution is present?

:)

[sundberg84]

@pellusfromtellus - to get a 100% right answer we ping @hek but I recommend paypal!

@pellusfromtellus

I think most of them handle paypal/card. You can press the "Order" button to find out. Nothing is binding until payment has been done.

Is there a drilling and outline file available?

[sundberg84]

@Paul-Robertson - hi!
Yes, but this is Eagles output gerber files.

Drill: SundbergMys9.TXT
Outline can be found in all other files:

Damn. Just missing the 0,1uF capacitor ..... to complete the 5v build. This will be my smallest build yet ;-) using PCB v9

IS it possible to use TP4056 (https://www.aliexpress.com/item/5-pcs-Micro-USB-5V-1A-18650-TP4056-Lithium-Battery-Charger-Module-Charging-Board-With-Protection/32728720869.html?spm=a2g0s.9042311.0.0.A0lkC7) this instead of using the step up booster?
Thanks!!

[gohan]

If you want to use a lipo battery, you need a voltage regulator

[sundberg84]

@hiddenuser - well not out of the box as mentioned by gohan. Im not really sure what you want to do. Its not possible to use this instead of step-up booster since it outputs 5v and the step-up needs to output 3.3v. But with a voltage regulator in between maybe? As I said - don really understand so maybe you can explain some more about your project?

[gohan]

@sundberg84 that tp4056 outputs just the lipo battery voltage

[hiddenuser]

Thanks @sundberg84 and @gohan

I have used made the board for 3.3v set up as per the instruction. I have usd the output from tp4056 into the Battery connector of the board I have a step board from https://www.aliexpress.com/item/New-Electric-Unit-1-PC-NEW-DC-0-8-3-3V-to-DC-3-3V-StepUP/32724361266.html According to the specification given in the same link it is supposed to stabilize to 3.3v above 3v but the sensor reports something else back to the gateway.

[sundberg84]

@hiddenuser - well, what would a battery measurer be if it reported a constant 3.3v boosted voltage? ;)
It all depends on how everything is connected (pictures?) but if you have connected it as battery instryctions the radio and voltage divider that measured the incoming battery are not a part of the booster circuit. This to prevent noice to the radio and to be able to actually measure the battery voltage and not step-up voltage which is the idea behind the board.

[gohan]

@hiddenuser I'm missing how can you use a booster to get 3.3v from a lipo battery
