jaredwolff I believe the 9131 does require more certification testing in order to legal deploy devices that use it. Versus the 9160, 9161 and 9151.
Agreed. The nRF9151 is the sanction proof nRF91 and what Nordic Semi recommends for all new cellular designs.
The nRF9131-EK is a very goodcompact reference design for DECT NR+ and LTE with J-Link OB that can be used as a dev board if the additional expansion offered by nRF9151-DK is not required.

Oh yea. Feather-ish formfactor. Didn’t realize they had something this small. Good on them.
AchimKraus Great news. How can it be ordered?
Btw @AchimKraus , the Recovery Fixture is available on the store now. The documentation is also updated: https://docs.circuitdojo.com/nrf91xx-feather-recovery-fixture/overview.html
Great! Do you currently have a schedule for the nRF9151 feather (beta-boards)?

Pre-order is now available. I have a few in stock I can ration between you and @zpm1066. Full availability Q1 2025. 
(I’m aiming for sooner though)
Great!
Any discount code possible? Mainly to compensate the shipping costs ;-).
Hi @AchimKraus
No discounts on the nRF9151 until it’s fully launched. These beta boards take a long time to assemble and test. Upshot is the tester is nearly complete.
Keep an eye out for upcoming discounts on the nRF9160 though..
On another note:
I played around with the nRF9151 Feather using nRF Connect for VSCode. Works well for those who prefer Nordic’s tools. Only big addition is to installing probe-rs or pyocd. Update to the docs are here: https://docs.circuitdojo.com/nrf9151-feather/using-vscode.html
On the current nrf9160 Feather USB does NOT play well when powering the device over the VUSB pin.
It would be nice if the next feather did for debugging purposes. I currently have my feathers deployed in 12V LiFePo battery powered systems with a buck converter to give me 5V for the feather and other devices.
I probably should’ve used the VBAT pin to power the feather, but it would be nice to add small lithium battery to act as a backup so I can continue logging power issues in the larger system.

Voxorin which version do you have again? Can you explain in what way? I removed the diode on 5V a few revisions ago.

Right now i’m powering it via the 5V pin for testing. So, it should work out in the field the same way. The only detail is whether or not it will be happy when you plug in USB.
VBUS pin is directly connected to USB in both designs now:

Gotcha!

I was wrong, this isn’t an issue with the current feather.
It turns out the issue only occurs when I use a C to C cable with my thunderbolt dock, and of course that’s the port I always use for testing haha.
Voxorin ok! Crisis averted
