@toyman I guess I made an error then. Thanks for pointing that out. In general, I haven't gotten much feedback on the PCB's that I've posted, so any feedback is always appreciated. :)

I actually think you were correct in your design, @NeverDie ;-)
A while ago part of the e73-2g4m04s schematic was posted on this forum:
Clearly the inductors to use the DC/DC converter are not connected to DCC. There is however a capacitor C17 from DEC4 to GND.
The Nordic reference schematic shows the missing L2 and L3, but capacitor C10 is actually present in the e73-2g4m04s (the mentioned C17, albeit only 100nF instead of 1.0uF in the reference):
Therefore I think your breakout is correct, as only the inductors between DCC and DEC4 need to be added to match the reference schematic :+1:

@Mika what is your experience regarding battery consumption on these?
I put together a sketch witch seems to work fine but one CR2032 just lasts a couple of days.
Sketch:

QFABC0
1646UUQFAB translates to 16kB RAM, 128kB flash and I can not even select this option in the arduino IDE. Can this be the problem?
@d00616 refer to his document for some high current consumption issue but I'm not sure what to do with the info.
Is there something wrong with my sketch or is there just an old crappy chip on the device??

So I tried your code with a more recent version of the chip and I have a power consumption around 1mA.
This is not surprising because in fact issue 39 seems to not be completely fixed, if I believe this link:
https://devzone.nordicsemi.com/f/nordic-q-a/577/current-consumption-when-using-rtc-ppi-and-gpiote#post-id-18533"The third revision hardware of the nRF51 has a solution for the GPIOTE OUT tasks, which has very low current consumption (<1uA). The third revision nRF51 hardware will be released in a few days. The third revision hardware still does not have a solution for the GPIOTE IN events, they still consume high current, so for low current applications, use the GPIOTE PORT event instead or the app_button libary."
From what I see it was never fixed.

I'm seeing a special offer for this at 2€ with coupon https://www.aliexpress.com/item/nRF52832-2-4GHz-Wireless-rf-Module-CDSENET-E73-2G4M04S-SPI-SMD-rf-Receiver-transmitter-Bluetooth-Module/32819293925.html

I don't know if it is a good one and I already have a bunch of stuff I bought still in the drawer :sweat_smile:

Thanks again for pointing out a possible solution but again I do not know how. I will just have to be patient and wait for someone to post an example of how to use one of the methods you mentioned.

I have started to test a NRF51822
and I can upload to it with Arduino IDE but I want to use vim + platformio. And I think i'm quite close :)

I'm trying to implement it right now, not really useful for me as I will only have one beacon board for which I will need it, but it's a good occasion to learn. I'll post my results here, but probably next week as I'll have short holidays :)

ok, I bought 2 of the nrf52 at half the price, now what would be the cheap solution among the programmers? Jlink is on the pricy side.

Cheap jlink clones with 4 wires from AliExpress/Ebay seem to work. So does the ST-Link v2 which is probably the cheapest option.
-
I got kind of lost with all those jlink clones with so many different versions. The ST-Link V2 I found it on digikey and similar sites for around 18/19€, is it the right one?

Don't do that. Either buy $2 clones or invest into DK or:
