The Omega2+ Expansion Dock is a development board that provides all of the interfaces your various modules, sensors, and USB devices might require. Access SPI, I²S, I²C, UART, USB 2.0, and Ethernet without the need for additional breadboards or soldering. It also provides a real-time clock with dedicated battery power. Just slot your Omega2+ into the expansion dock, and use it like you would a Raspberry Pi or any other single-board computer.
Here at Factorial Group, we have incorporated the Onion Omega2+ into several of our IoT, industrial automation, and robotics projects. Along the way, we encountered a number of challenges:
To address these shortcomings, we decided to design and manufacture a convenient, inexpensive dev board for embedded Linux developers and other users of the Omega2+.
To make use of the Omega2+ Expansion Dock, you will of course need an Omega2+ IoT computer module. If you don’t already have one, you can pick one up at the official Onion store or from Mouser.
Omega2+ runs the LEDE distribution of Linux on an MT7688 SoC, which operates at 3.3 V and includes a 580 MHz MIPS CPU, 128 MB of DDR2 DRAM, and 32 MB of flash storage (expandable through MicroSD). It supports 802.11 b/g/n Wi-Fi at 2.4 GHz and 10/100 Mbps Ethernet. It does not, however, include an Ethernet port, which is one of the many utility features of the Omega2+ Expansion Dock.
Documentation for the Onion Omega2+ IoT computer module is online. If you have any questions, you can reach us using this campaign’s Ask a technical question form.
Produced by Factorial Group in Kiev, Ukraine.
Sold and shipped by Crowd Supply.
