Not so long ago, the typical development board was big, bulky, and often handmade. Recently a flood of Lilliputian-size development boards has been released — one for just about any need.
We’ve assembled a collection of 10 boards so small you might lose them in the cushions of your couch. Click on to the next page to begin.
The Femtoduino, an incredibly tiny Arduino clone, will use the Arduino compiler and should work with Arduino libraries, as well. It weighs only two grams and sports the computing power of an AT Mega 328p, just like the Arduino UNO. Its makers call it the smallest Arduino clone available.
The Digispark is a close contender for smallest of these small boards. It costs less than the Fem to dui no but doesn’t have quite as much power. The processor at the core of the Dig spark is the AT Tiny 85. There are six IO pins to choose from; two are reserved for USB. It may not be as strong as the Arduinos or have the same pin count, but the lower cost is a happy compromise.
