zpm1066 btw - I’ve been field testing nRF9131-EK for DECT NR+ and LTE-M/NB-IoT with GNSS. A very neat board, slightly longer than a Sparkfun Thing+ board, with nPM1300, nPM600, 256Mb external flash memory, and a Segger J-link OB. There are a few more enhancements coming down the line to make it even better.
I believe the 9131 does require more certification testing in order to legal deploy devices that use it. Versus the 9160, 9161 and 9151.
I have not made progress. I’ve been focusing elsewhere. I have been playing with using probe-rs instead as it has been added as a target recently for Zephyr. I ported the pyocd code that updates the modem firmware also to use probe-rs (and using it in production). So I’m leaning to use that.
Just to mention: the nRF9161 prototype does a pretty well job on my side. Works since August without issues.
That’s amazing to hear. Thank you for testing it @AchimKraus !
AchimKraus The pin VUSB is power input from USB? So it’s possible to power the device via that pin, if no USB is connected?
VUSB is connected direct to the headers so you could power the device through the pin:
I have not tested if it plays well with USB. (it may work just fine) I typically recommend using VBAT pin for external power and turning the charger off. It depends on your application though.
