akorIoT Nano with Arduino Nano / STM32 Nucleo 32 and NB-IoT, GSM and GNSS module

NB-IoT reference design in credit card size including PCB track antenna

The wireless IoT market is crying for small mobile devices transmitting for years from tiny batteries. With akorIoT Nano we developed the next open design.  “akor” is the Proto-Celtic word for “open”. With placing the order for akorIoT Nano you get the schematic diagrams, some demo code for a unique PCB with NB-IoT-, GSM-, GNSS module in credit card size (85 mm x 55 mm), five sensors, including the embedded cellular antenna.

The akorIoT team offers not just a plain piece of wireless IoT hardware. You have the freedom to ask for antenna matching of any kind of antenna bought by any party up to placing an order for your own customised antenna. One reason for an own antenna will be maybe cost reduction. Another reason is that rectangle chip antennas does not fit in “round corners”. The akorIoT team is able to develop antennas in different shapes up to copper structures sprayed inside of the plastic enclosure.

The basic akorIoT Nano will cost Euro 119. The Arduino Nano or STM32 Nucleo is Euro 20 on top. The software development environment is free of charge. The battery for quick setup you can pull out of your old smartphone. Your main invest will be your time. Ask for details by email to harald.naumann (at) lte-modem.com or info (at) akorIoT.com

  1. Dear Mr. Naumann,
    do you have more infomaterial how the Extension to bridge to LoRa and BLE for the akorIoT Nano looks like and what is the Price for? I would need a modul with NB-IOT, Lora and BLE in it and another modul with NB-IOT and BLE – can you offer such a moduls?
    THX in advance!
    br, Josef

  2. Dear Mr. Geider, yes I do but it is to complex to share it with the answer to a comment. Just to let you know that our NB-IoT seminar will stay in week 41 in Vienna.

  3. Hi Harold,

    Please can you send me a proposal or some engineering services to make your IoT idea a cost-effective reality.
