Arduino Nano33 BLE sense NRF52840 Processor BLE, AI enabled , multiple on board sensors finger size arduino and python supoort

The Arduino Nano33 BLE sense NRF52840 board, officially the Arduino Nano 33 BLE Sense, packs a Nordic nRF52840 processor with Bluetooth Low Energy and a set of onboard sensors into the small Nano form factor. It can run machine learning models with TensorFlow Lite for Microcontrollers and is programmed in the Arduino IDE or in MicroPython, which makes it ideal for wearables, smart sensors and AI-at-the-edge projects.
