"The Onion Omega2+ comes packed with built-in Wi-Fi, a MicroSD slot, a Linux Operating System, and a powerful processor, among other things. The new expansion dock has been created to enable users to easily connect sensors, modules, USB devices and more."
"Con interfaces SPI, I2S, I2C, UART, USB 2.0, y Ethernet, este dock de expansión para placa de desarrollo se conecta de forma muy fácil para trabajar gobernado por un sistema operativo GNU/Linux."
"Without the need for additional breadboards or soldering, it can access SPI, I2S, I2C, UART, USB 2.0, and Ethernet.To fulfill it’s functions, just slot the Omega2+ into the expansion dock and use it like any other single-board computer."
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+.
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.
The Omega2+ Expansion Dock will be fabricated and assembled by PCBWay in China. There, each board will be electrically tested before being sent to Crowd Supply for fulfillment. We have worked with PCBWay on the Omega2+ Expansion Dock prototypes, among other projects, and we are confident this production run will go smoothly.
As with any venture, this one will involve some risks. Our design is quite stable at this point, so the risks are primarily in sourcing and logistics (component shortages and shipping delays, for example). A high failure rate during manufacturing could require us to produce a second batch, which would delay delivery. Any such delays will be communicated clearly and promptly to backers through project updates.
