Introduction

The Onion Omega2 is a Wi-Fi enabled, Linux-based development module, designed specifically for IoT applications. It provides a drop-in, low-power solution ideal for prototyping and building IoT hubs and devices. It features a MIPS 24KEc processor running at 580 MHz, built-in DDR2 DRAM, flash storage, and a 2.4 GHz 802.11b/g/n Wi-Fi radio. It supports a wide variety of I/O protocols, with dedicated pins for USB 2.0 and ethernet, and 18 pins available to the developer. The module is self-contained and only requires a power supply to operate. Measuring 42.9x26.4x9.9 mm, the Omega2 is a very small, self-contained, plug and play computing and connectivity device. It is a through-hole device, featuring 32 pins at a 2mm pitch. For prototyping and proof-of-concept work, it can be plugged into any of the Onion Omega2 Docks that provide ports, serial command line access, easy access to I/Os and more. At the next stage of development, custom hardware can be designed to accept the Omega2 depending on the end user’s specific needs. Onion also provides the Omega2S, a surface-mount version of the Omega2, designed specifically for high volume production. By virtue of the pre-loaded Linux operating system, developers can create their own applications using a programming language of their choice, and make use of existing network stacks and a rich set of software packages to implement their desired software functionality.
