This Audrino device is TINY! …
Arduino’s Nano line will soon welcome four new products. They’re all small boards like the classic one, making Nano a family of small boards meant for compact projects. All the new boards boast low energy consumption and processors more powerful than what the classic has. Even better, they’re all pretty affordable: the most basic entry called Nano Every, which you can use for “everyday” projects and can replace the classic Nano, will even set you back as little as $9.90.
The Arduino Nano 33 IoT will cost you twice that much ($18), but it’s compatible with Arduino’s Internet of Things application platform and can run connected devices. For projects like wearables that require Bluetooth and low power consumption, there’s the Arduino Nano 33 BLE, which is priced at $19. But if the device needs sensors for proximity and gesture, as well as various environmental sensors, then the Arduino Nano 33 BLE Sense is the best choice. It even has an embedded microphone and costs only $29.50.
