Nordic Semiconductor Nordic Thingy:52 IoT Sensor Development Kit for nRF52832

The Nordic Semiconductor is an easy-to-use prototyping platform, designed to help in building prototypes and demos, without the need to build hardware or even write firmware. It is built around the nRF52832 Bluetooth 5SoC. All sensors and actuators can be configured over-the-air using Bluetooth Low Energy. It makes it possible to create demos and prototypes without starting from scratch. It connects to Bluetooth Low Energy-enabled smartphones, tablets, laptops and similar devices, and it sends/receives data from/to its sensors/actuators to an app or cloud. It includes an NFC antenna and has 1 button and 1 RGB LED that simplifies input and output. The speaker for playing pre-stored samples, tones or sound streamed over Bluetooth low energy (8-bit 8kHz LoFi). It is used to sense movement, orientation, temperature, humidity, air pressure, light, colour and air quality.
