Thingy:91 is certified for global, low-power, long-range LTE-M/NB-IoT applications. The device also features Arm TrustZone security, has a range of sensors, and provides embedded support with a Nordic nRF52840 advanced multiprotocol SoC for short-range wireless technologies such as Bluetooth 5, Thread, Zigbee, and ANT.
The devices also includes a Nano (4FF) eSIM card from iBasis with 10MB of data for out-of-the-box cellular LTE-M and NB-IoT connectivity.
The Nordic Thingy:91 is provided in a 6 x 6-cm plastic and rubber case with a USB connector fpr charging the internal 1440 mAh Li-ion battery. Environmental sensors include temperature, humidity, air quality, and air pressure, and colour and light. There are also separate low-power and high G-force accelerometers.
The nRF9160 is a low power SiP measuring 10 x 16 x 1mm, while integrating a dedicated application processor and a multimode LTE-M/NB-IoT modem. The application processor includes a 64MHz Arm Cortex-M33 CPU with 1MB Flash and 256KB RAM dedicated for the application. The nRF9160 SiP features ARM TrustZone and ARM CryptoCell, as well as a range of interfaces to communicate with sensors and actuators.
The nRF9160 SiP integrates GPS support to allow a combination of GPS and cellular data to be used for more accurate positioning.
The Nordic Thingy:91 can be programmed using Nordic’s dedicated cellular IoT ‘nRF Connect SDK’ with integrated Zephyr RTOS.
