Onion Omega is an Atheros AR9331 Wi-Fi Module Supporting Various Docks and Add-on Boards (Crowdfunding)

There are so many inexpensive Wi-Fi modules running Linux that it would be easy to discard Onion Omega as yet another Wi-Fi module based on Atheros AR9331 WiSoC. However, the developers have tried to bring some added value by making programming easier for web developers, integrating it with a cloud platform (free for non-commercial use), and providing basicor Arduino dock, and add-on boards for Ethernet, OLED, Relay… to make building hardware projects easier too. Let’s go through the hardware first, starting with the module specifications: SoC –  Atheros AR9331 400MHZ MIPS 24K System Memory – 64MB DDR2 400MHz Storage – 16MB Flash Connectivity – 10/100 Mbps Ethernet + 802.11b/g/n Wi-Fi up to 150Mbps with PCB antenna w/ uFL connector I/Os –  18 GPIOs USB – 1x USB 2.0 Power Supply – 3.3V; Typ. consumption: 0.6W Dimensions – 28.2mm x 52mm (1.1″ x 2.0″) Since this type of module is not […]
