These boards measure in at only 31 x 15.5mm, and weigh 1.85g. These boards feature an ATmega32U4 chip, allowing them to emulate a USB keyboard, mouse, or whatever human interface device (HID) you desire.įor extreme tininess, it’s hard to beat the Adafruit Trinket. It is, however, similar in function and name to the Arduino Micro, as well as the retired Arduino Pro Mini, which is more closely related to the Nano. Often referred to as the “Arduino Pro Micro,” this board isn’t actually an Arduino product. Once programmed, they can be used in the same space and with many accessories originally meant for the Nano. Available with up to 256K of flash memory, these boards run on a 32-bit ARM processor and can be programmed in a variety of IDEs. Arduino has even made an adapter board that allows UNO footprint shields to be used with the MKR footprint, which makes industry development streamlined for those who want to scale with the MKR.įor enhanced capabilities in the same form factor as an Arduino Nano, the STM32 Nucleo-32 series of boards present a variety of options. Importantly, it includes WiFi capabilities, and also features a real-time clock (RTC), analog output, and built-in Li-Po charging. While one of the larger “mini” boards here, it’s still less than half the footprint of the Uno, and is powered by a SAMD21 Cortex-M0 32-bit processor, operating at 48 MHz. If you’d like to stay within the official Arduino family, the MKR1000 is an excellent choice for its small size and enhanced features. The Nano gets its size down by eliminating the DC power jack and utilizing Mini-B USB. While the Uno board measures 68.6 x 53.4mm at 25g, the Nano measures only 18 x 45mm at 7g. If you like the Arduino Uno, but just want it smaller, then the Arduino Nano provides very similar specs. 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. ![]() 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. ![]()
