Will try to share soon. Almost all elements are 0402.

Wow! I have been struggling with 0603 size. You must have eagle's eyes :eyes:

[pepson]

But v2 is also for radio RFM69HW ?

[Koresh]

@pepson Yes. radio footprints are the same. You can use HW or CW via adapter.

[pepson]

@koresh

Ok please share list components... i wait for it.
And diffrent with v1 and v2 is only that v2 have two batteries ?

[Koresh]

@pepson Yes. So it have longer lifetime, radio range and working temperature range.

[pepson]

@koresh

Ok thanks. only wait for list component

[pepson]

Hi
Can you share your project file and file gerber with this specification
https://support.jlcpcb.com/article/44-how-to-export-kicad-pcb-to-gerber-files

Or can you put description to also file gerber ?
Thanks

[pepson]

Description to model elemnts. Ex. U4

[pepson]

Please share also layer describe...

Failed load project to production.

You mixed gerbers of the main board and adapter board.

It is standard. If you really need it you can find layers description here

No I can't. Have no time today, sorry.

Can you explaine me more ? What can i do ?

[Koresh]

@pepson
pcb2.* - main boards gerbers
rfm69c_to_rfm69hc.* - adapter gerbers
You need only main board gerbers

Hi @koresh I'm having problems with battery monitor. Trying to find out what's wrong, I have realiced that A6 analog reads from regulator output. So It allways reports 3,3V, isn't it?

Also, I read that unregulated could go up to 6,5V. Wouldn't this destroy radio module? I think I'm missing something.

Thanks.

[diogoc]

Hi. Do you have unassembled pcbs to sell?

[Koresh]

@gerator Oh.. so sorry. It is new forum reporting system. Didn't saw your message.
A6 reads unregulated voltage (3.5-6.5V) through divider (1/3). So it can't destroyed nothing.

[Koresh]

@diogoc I will try to find them. But all of components are 0402... :eyes:

@Koresh I still have a bunch of v1 boards that I never got to work because of power consumption (I presume). I thought I'd make one more attempt.

I tried bridging the jumper and I'm using a 2032 battery. Consumption varies between 2 and 4mA on different boards. On some boards it fluctuates a lot. The instructions above are not immediately clear. Do I have to remove the LDO AND capacitors as well?

[yury]

@bjornhallberg

while measuring current draw , was there FDTI adapter connected also?

[bjornhallberg]

@yury No I ran them on just a 2032 battery at the time, just had it in an external battery holder. I also removed the LDO on one of the boards and bridged the two top pads, with no apparent effect.

Unless there is something wrong with my DMM.

[alexsh1]

@bjornhallberg I have the same v1 board you have with a sleeping power consumption being 5uA. I also have Si1132 sensor soldered and had some issues with power consumption initially as the standard Si1132 lib did not implement sleep function for this sensor.

1. what sensors do you have? Do they properly put to sleep? BH1760?
2. can you share the sketch?
3. removing the LDO will not help you to bring down consumption from 3mA. 3mA most likely mean your radio is not sleeping. Such consumption will kill CR2032 very quickly - no chance running the board on such consumption
4. did you try a different multimeter?
5. there could be a problem with one of the tantalum capacitor. @yury could you remind which one has to be removed please?

I suggest you start with 5)
