The Onion product line revolves around the Omega2+, an easy-to-use, expandable IoT computer packed with built-in Wi-Fi connectivity, a MicroSD card slot, and a powerful 580 MHz MIPS processor. Though just a fraction of the size of other single board computers, the Omega2+ is a full computer with a Linux operating system, 128 MBytes of DDR2 memory and 32 MBytes of flash storage. The device also offers 15 general-purpose inputs and outputs (GPIO), two PWM, and two UART interfaces. Mouser also now stocks a variety of docks and expansion boards, which provide additional functionality to the Omega2+ board.
