μduino May Be the World’s Smallest Arduino Board (Crowdfunding)

OLIMEXINO-85S may have held the title of the world’s smallest Arduino (compatible) board for the last few years, being barely bigger than a micro SD card as it measures about 16.9 x 12.7 mm, but there’s a new mini champion in town with μduino board measuring just 12 x 12 mm.

μduino prototype

μduino board specifications:

  • MCU – Microchip Atmel ATMEGA32U4 8-bit AVR microcontroller @ 16 MHz with 2,560 bytes of RAM, 32KB flash, and 1024 bytes of EEPROM (Arduino Leonardo compatible)
  • I/Os
    • 6x Analog I/O ports
    • 14x Digital I/O ports (including Rx/Tx) including  7x PWM
    • 1x Analog reference voltage port
    • 1.27mm pitch
  • Programming / Debugging – 1x micro USB port; 6-pin ICSP programming ports (load custom bootloaders, program other boards, etc)
  • Misc – Status LED, reset button
  • Power Supply – 5V via micro USB port; 5V voltage regulator (accepts up to 16V DC);  2x 5V ports;  2x ground ports
  • Dimensions – 12x 12 mm with 2 mounting holes (prototype is 14×14 mm)
Sizes Comparison: Arduino UNO vs Arduino Nano vs μduino

The µduino board is said to be particularly suited for projects such as a mini quad-copter, a GPS logging module, small multimeters, heart rate monitors, and other wearables. The project has launched on Crowdsupply with a $5,000 US funding goal. While µduino may be the smallest Arduino board, it’s not quite the cheapest, as you’d need to pledge $18 to get the board with a micro USB cable. Shipping is free to the US, and $7 to the rest of the world, with delivery scheduled for the end of September 2017.
