This is big news today from Nordic Semiconductor! The #nRF9151 is here, which is a drop-in replacement for the #nRF9161 and #nRF9160 (albeit with a 20% smaller footprint) with all the amazing features, but that adds Class 5 output power which even further reduces power-consumption.
This is a small lecture I gave to a team of students on how to approach designing the software architecture for a #cellularIoT project.
It uses the Nordic #nRF9160 as a habit tracker in a 12 sided enclosure and connects to AWS IoT.
In the talk I speak about:
- design considerations
- how to separate work between three teams
- make sure the project is aligned with the user's goals
- how end-to-end tests support integration between teams

#NordicSemiconductor launches the Connect for Good: Low Power Sustainability Challenge in collaboration with Wevolver and contest sponsors Mouser Electronics, SORACOM, and Crowd Supply.
The most innovative idea solving issues related to sustainable living and the environment will receive a grand prize of $20,000 and in-kind project support.
The first 100 valid entries will receive an #nRF9160 Development Kit!

Another showcase that is using the demo application I have been building the last weeks is used here to demonstrate a #NordicSemiconductor #nRF9160 connected to the internet without a physical SIM, using the #Onomondo #SoftSIM!

@schiermi @chris_gammell This is the guide that covers what has significant influence on the power consumption of the #nRF9160: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/app_dev/optimizing/power.html#power-saving-features
The biggest cost is using the modem, so the less frequent you send data the better.
We recently did measurement with the asset_tracker_v2 sample for CES 2023 and the solar demo we showed, and arrived at 3.4 mA average if you send data to the cloud every minute, and 2.3 mA if you do it every hour.
@rdmueller Exeger demoed this at CES this months, so it's quite new. I am not aware that the shields can be purchased, right now, but Powerfoyle itself is available and you can order a DevKit at https://www.exeger.com/sign-in/.
In good conditions we get over 4.5mA which is enough to send data to the cloud every minute using the #nrf9160
