Overview
The Nano Every is Arduino’s 5V compatible board in the smallest available form factor: 45x18mm!
The Arduino Nano is the preferred board for many projects requiring a small and easy to use microcontroller board. One example is low cost robotics, where the Nano is broadly used. If you are in the situation of needing many boards for your classroom, or if you need to present a complex prototype with many functional blocks, this pack will offer you exactly what you need: a series of Arduino Nano Every boards at a discounted price.
The Arduino Nano Every is an evolution of the traditional Arduino Nano, but featuring a lot more powerful processor, the ATMega4809. This will allow you making larger programs than with the Arduino Uno (it has 50% more program memory), and with a lot more variables (the RAM is 200% bigger).
The pack is available in two sizes with either 3 or 6 boards of Arduino Nano Every without headers. Whether you want to minimize the size of your prototypes or share the joy of electronics with your friends, this is the best option you will find.

Easily monitorize your garden's environment with simple components.

Greenhouses are excellent ways to grow plants due to their compact nature and the fact that they can absorb and store the sun’s light as heat to keep their internal temperature higher than outside. But when it comes to adding ventilation for cooling things down, decreasing the humidity, or simply to avoid rain, most non-commercial ones still rely on someone to manually open or close the windows. This need for automation is what drove Michael Bernhard to create his own greenhouse climate regulation system. This project relies on a Nano Every to read the ambient temperature/humidity as well as control up to six motorized windows via three L298N dual H-bridge drivers. The Nano receives commands and other data over WiFi from an accompanying ESP8266 board for wireless remote control with a mobile phone. Each of these components and their connectors were added to a custom PCB and placed within a simple wooden enclosure to keep moisture out. An LCD at the top shows pertinent information such as the time, temperature, and humidity. The aforementioned WiFi control scheme not only allows for remote control of the windows, but also for the visualization of historical sensors data on a graph. Safety information, including errors and stored EEPROM data, can be viewed on the web application, too. To see more about this project, you can read Bernhard's write-up here on Hackster.io.
FAQs
Batteries, Pins and board LEDs
- Batteries: the Nano Every has no battery connector, nor charger. You can connect any external battery of your liking as long as you respect the voltage limits of the board.
- Vin: This pin can be used to power the board with a DC voltage source. If the power is fed through this pin, the USB power source is disconnected. This pin is an INPUT. Respect the voltage limits to assure the proper functionality of the board.
- 5V: This pin outputs 5V from the board when powered from the USB connector or from the VIN pin of the board.
- 3.3V: This pin outputs 3.3V through the on-board voltage regulator.
- LED ON: This LED is connected to the 5V input from either USB or VIN.
