Just a minor upgrade of my NB-IoT Hat Cleaned up ground plane, remove one UART, added new SWD and resistors on SPI1. I have still not have time to assemble test the previous one, so will do that as soon as I get a SIM card.
This Hat is cool because NB-IoT means you buy a SIM card with close to no monthly cost and send data from anywhere you can connect. NB-IoT is gaining momentum in Norway, so I am on my way to get a SIM card.
