Board based on Atheros AR9331 CPU and ATmega 32u4 MCU. It is a smaller version of the turquoise board with a breadboard-friendly form factor.
The Qualcomm Atheros CPU runs at up to 400MHz supporting a Linux distribution based on OpenWRT named Linino OS and an ATmega32u4 MCU for GPIO control. The board has built- in Wi-Fi (IEEE 802.11b/g/n up to 150Mbps 1x1 2.4GHz), it has 20 digital input/output pins (up to 7 can be used as PWM outputs and up to 12 as analog inputs), a 16MHz clock, a micro USB connector, TWI, SPI, UART interfaces, an ICSP header, two reset buttons, and one user button.
