This Arduino-compatible development board is a smaller version of the popular Leonardo. It measures just 23 x 20mm and is a great choice when you need a low-cost and compact Arduino project. The power and three of its analogue and digital pins go to large gold-plated tabs, making them suitable to connect alligator clips or for sewing onto clothing with conductive thread (sold separately). The board features a 32u4 ATMEL processor with a 16MHz clock, 10 x digital pins, 5 x analogue pins, 4 PWM pins, ICSP, I2C, and a serial port.
