The venerable Arduino Uno is the de facto standard in microcontroller development boards, but there are also other boards that can be hidden in a project to make it “smart.” Some even provide extra features like built-in Bluetooth or WiFi capabilities. While the Uno will certainly be used for years to come, due to its familiar form factor and available accessories, here are nine other options in even smaller form factors to hide in your project.
If you like the Arduino Uno, but just want it smaller, then the Arduino Nano provides very similar specs. While the Uno board measures 68.6 x 53.4mm at 25g, the Nano measures only 18 x 45mm at 7g. The Nano gets its size down by eliminating the DC power jack and utilizing Mini-B USB. (more…)
