The Thingy:52 development kit is a a fully-loaded sensor platform that is ready for web and app connections. Like the nRF52 DK, the Thingy:52 platform is built on the nRF52832. The nRF52832 is Bluetooth 5 ready, although it does not support the new long-range LE Coded PHY.
The Thingy:52 development kit is designed for developing demos right out of the box. The range of components provided with this dev kit is impressive and useful for many Bluetooth prototyping scenarios.
- Color/light sensor
- Gas sensor
- Humidity (and temperature) sensor
- Pressure (and temperature) sensor
- Digital microphone
- 9-axis IMU (accelerometer, compass, gyroscope)
The kit comes fully assembled with a charged battery. Demo firmware is flashed by the factory, allowing you to test out the device immediately by using demo smartphone applications.
Nordic provides excellent documentation for the Thingy:52. Source code for the iOS, Android, and web applications are available for download. Nordic also provides an example Node.js library for working with the Thingy:52.
This is an extremely versatile prototyping platform for Bluetooth sensing applications. It's also just fun, since it comes pre-loaded with peripherals for you to play around with.

About the nRF52832
The nRF52832 is the mid-tier Bluetooth 5 chip. The nRF52832 is built on a Cortex-M4F processor. The nRF52832 provides a significant increase in flash, RAM, and peripherals over the nRF52810. These improvements make the nRF52832 an attractive choice as a primary processor for your system or for exploring new BLE features like IPv6 support. The nRF52832 includes an on-chip NFC tag to support out-of-band pairing. You can utilize the NFC pairing method for a simpler process of exchanging authentication information between two bluetooth devices.
