NB-IoT shield with Arduino header renamed to akorIoT

NB-IoT Shield Arduino

The idea for the NB-IoT shield with Arduino header was conceived in summer 2016. We then produced the first version of the NB-IoT shield at the M2M Summit in September 2016. The second generation was shown to readers of my IoT/M2M Cookbook in our end of the year mailing and it has proved extremely popular; we […]

HARdunio – Arduino footprint NB-IoT shield update

Arduino shield with NB-IoT module

We have extensively tested the HARduino board over the past few days. We have been testing the GSM version due to the lack of NB-IoT coverage in the region of our office in the North of Germany but both NB-IoT and GSM exhibit the same characteristics in the tests we carried out. The AT command set […]

World’s first free and open IoT out of the box with NB-IoT module with Arduino header

NB-IoT-LTE-Cat-NB1-M1-Arduino-Shield

Many IoT / M2M Cookbook customers asked me for an evaluation kit within the last two years. I launched the first version during M2M Summit in September 2016. In February 2017 the multicellular version came true. The working name is HARduino because it has an Arduino R3 compatible UART interface. HARALD – ALD + duino […]

GPS antenna selection for a GSM / GPS tracker – DUT 3

GPS chip loop antenna temperature drift

Interference of temperature on GPS antenna resonant frequency The device under test is a PCB of size of 40 mm x 20 mm, again with a GNSS antenna for a small tracking device. Small mobile GSM / GPS trackers are common for pets, humans or assets. Chip antennas operate as loop antennas which are magnetic […]

Helical GPS antenna versus GPS chip antenna

Q: I came across a blog of yours some years back. By chance are you still offering assistance with GPS related antenna solutions? If so, we are trying to find a replacement for a Sarantel helical antenna.  We need to match or improve upon the performance of the Sarantel product. We are looking into Maxtena’s […]

Low Cost GSM GPS Bluetooth module on Arduino shield

GSM GPS Bluetooth module as a glance

New GSM / GPS / Bluetooth module adapter for STM32 Nucleo, Arduino, Intel Galileo plus compatible PCBs Your ideas? Your wishes? Your recommendation? Your advice? I will listen to you. Before I started to write the IoT / M2M Cookbook I asked business friends what they would like to pay for such a book. A […]
