💬 Easy/Newbie PCB for MySensors

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

@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

[dakipro]

hey, has anyone maybe made a fritzing drawing/component of the board?
I know, I'm lazy as f but.. since the board is that easy, documenting with it could be easy as well :)

[markjgabb]

@sundberg84 interesting question...or maybe stupid question not sure...

i have a tonn of 3v pro mini's but im thinking of mains powering some for motion sensors.... would i set it up as battery, and then just use a voltage regulator on where the step up usually would be? or is there a better way to handle it?

[gohan]

there is a voltage regulator footprint on the pcb made for that
