NB-IoT shields with Arduino header plus consulting, service and antenna design in support with a value of Euro 10000+ to win

Today the bunny will jump out of the heat. Next week at the embedded world you have a chance to win a Gold, Silver, Bronze and Student kit. The Student kit has a higher value than the Bronze kit. Students are our future. All kits together have a value of mare than Euro 10000. The […]

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 […]

Antenna Tutorial -Self-made PCB antenna for NB-IoT and GSM for cost US$ 0

Self Made Embedded Antenna Design versus Chip Antenna The wireless Internet of Things has a need for inexpensive wireless modules and antennas. An LTE-Cat-NB1-module (NB-IoT) will cost less than US$ 6 at 1K order. A self-made NB-IoT antenna on PCB could cost US$ 0. Within 60 minutes you will learn which is commercially and technically […]

Wi-Fi module – five minute set up

This Wi-Fi module arrived yesterday.  The complete package includes the Wi-Fi module,  a USB connector and a Serial Peripheral Interface (SPI) to USB converter. The operating voltage is supplied via USB from the PC. After plugging the module into the USB port, a standard terminal software application was started on the PC. With the first […]

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 […]

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 […]
