nRF6943 - Nordic Thingy:91 nRF9160 Multi-sensor Cellular IoT Prototyping Board

The Nordic Thingy:91 is a battery-operated prototyping platform for cellular IoT, certified for global operation. It is ideal for rapid development of prototypes for cellular IoT systems and is especially suited for asset tracking applications and environmental monitoring.

Nordic Thingy:91 includes a set of sensors to gather data about its own movements and the surrounding environment. Temperature, humidity, air quality, air pressure, color, and light data can easily be extracted for local or remote analysis. For input, the Nordic Thingy:91 offers a user-programmable button. Visual output is achieved with user-programmable RGB LEDs, while a buzzer can provide audible output. The standard application firmware on Nordic Thingy:91 extracts the data from the different sensors and relays it securely to the nRF Connect for Cloud, where it is displayed in a user-friendly interface. The LEDs can be controlled remotely through the same interface.
The firmware supports concurrent operation with LTE Link Monitor, a tool providing an AT command interface enabling link and network testing. The firmware has been developed using the nRF Connect Software Development Kit (SDK). It is open source and can be leveraged and modified to suit your specific needs. The firmware can be updated and debugged by using an external programmer/debugger, for example with the one on the nRF9160 DK (Development Kit).

 

Nordic Thingy:91 integrates the nRF9160 System in Package (SiP), supporting LTE-M, NB-IoT and Global Positioning System (GPS), and the nRF52840 System on Chip (SoC), supporting Bluetooth Low Energy and Near Field Communication (NFC). Source code for firmware, hardware layout, and schematics are all available for free.

Nordic Thingy:91 has an antenna supporting GPS, LTE-M, and NB-IoT that enables it to support a global range of LTE bands. It has two antennas connected to the nRF52840: a 2.4 GHz antenna for Bluetooth LE and an NFC antenna. To connect to cellular network out of the box, Nordic Thingy:91 has a nano/4FF SIM card slot and is bundled with an eSIM card from iBasis that comes preloaded with 10 MB.

 

A 1400 mAh rechargeable Li-Po battery is also part of this prototyping platform giving a smooth transition into prototype field-testing.
