Onion is a small company created by artists, engineers and craftsmen with offices in Boston, Toronto and Shenzhenie. After a failed attempt to create the design of miniature thermal printer the staff of the Onion decided to look for ideas on new solutions required by the modern technological world. In 2016, the company has developed and introduced to the market Onion Omega – minikomputer running on the Linux operating system, with the possibility of connection via wi-fi network. The project jednopłytkowego computer was launched in 2015 campaign crowdfundingową on the portal Kickstarter. Onion Omega2 wi-fi and Omega2 Plus wi-fi is a small platform for the development of that open before you new world of possibilities in the field of IoT – the Internet of things.
One of the smallest IoT modules available on the market that are running on Linux. It works on the basis of a processor Mediatek MT7688 with frequency signal 580 MHz, has 64 MB RAM and 16 MB of internal Flash memory. In addition, there is a wi-fi module and the interfaces: 15x GPIO, PWM, UART, I2C, SPI.
One of the smallest available on the market IoT module that are running with Linux. Works on the basis of processor Mediatek MT7688 with frequency signal of 580 MHz, has 128 MB RAM and 32 MB of internal Flash memory. In addition, there is wi-fi module, reader of memory cards microSD and interface 15xGPIO, PWM, UART, I2C, SPI.
Extension module for Onion Omega 2, which allows, among other, to power the device via a microUSB port and a built-in stabilizer 3.3 V. In addition, it has a Converter UART-USB, a USB connector, an RGB LED, reset and power buttons. Derived pins GPIO for a female connector enables the connection of additional extensions.
Extension module for Onion Omega 2, which allows, among others, to powered the device with a battery lipo 3.7 V or via microUSB. It has a built-in stabilizer 3.3 V port 3.7 V lipol raster 2.00 mm, USB connector, reset and power buttons. The extension also has derived GPIO pins, so it is very useful in projects where they are used.
Extension module for Onion Omega 2, which allows, among other, to power the device via a microUSB port and a built-in stabilizer 3.3 V. In addition, it has a Converter UART-USB, a USB connector, reset and power buttons. The ectension has no derived GPIO so it is also bery useful in projects where these pins are not used.
The board allows for independent creation of electronic circuits. There is a connected extension type dock for Onion Omega. It has two-way mounting hole (raster 2.54 mm), allowing to solder the goldpin connectors, sensors, modules and integrated circuits in a DIP case.
Extension for Onion Omega2 with ATmega microcontroller ATmega328P known from Arduino Uno. The communication between the chips is performed through a serial UART interface programmable in the Arduino IDE environment. The module allows you to connect popular extensions, so-called Arduino Shields.
Extension for Onion Omega2 to manage devices with power consumption up to 60 W from the minicomputer. The system has two relays for switching voltage up to 250 V AC at current up to 2 A, with maximum power up to 60 W. The system communicates via the I2C bus.
Extension for Onion Omega2 allows you to generate the PWM signal, which is used to control servos and DC motors. The system has 16 independent PWM channels, DC power connector and a socket with derived GPIO pins, communicates via the I2C bus.
Extension for Onion Omega2 enablec communication NFC / RFID with frequency 13.56 MHz. The extension uses the controller PN532, which finds application in smartphones and NFC-supporting devices. It can read and save tags and cards, communicates with phones, for example, during the payment process. The set includes 2 NFC stickers.
Extension for Onion Omega2 with Converter ADS1115 ADC enabling the connection of analog sensors. The extenions has analog channels, each with 16-bit precision. On the board there are three additional Grove connectors. For connection of the extension it is also required to have a extension type Dock, for example Espansion Dock.
Heart “bulbs” in the last game, with the first version of the Mediatek processor MT7688 clock frequency to be processed is 580 MHz. We find here also the internal memory of 128 MB and FLASH memory of 32 MB that can be expanded because it is located on the PCB of the memory card reader microSD. Platform Omega2 wi-fi and Wi-Fi Plus Omega2 supports programming languages such as Python, Perl, Ruby, Node.js C++, Lua, php, BASH, as well as the environment Node-red, which allows modeling and simulation of the processes in a simple way for beginners. Miniature computers Onion IoT can work with computers running based on Windows operating systems, Linux and macOS. Thanks to the plates Omega2 wi-fi and Omega2 Plus wi-fi you will be able to design and implement automation budynkową where control will be connected via Internet, for example, with Your machine. Just use your imagination and create interesting projects IoT – technology of tomorrow!
An important advantage of the latter minikomputera Bow is its modularity. In our offer you will find attractive accessories for use with Omega2 wi-fi and Omega2 Plus wi-fi, such as accessories, modules and expansion hardware Expansion Dock free Dock, Mini Dock, Power Dock, OLED Expansion, Expansion Relay, Bluetooth BLE Expansion GPS Expansion – USB and many others. The connectors onboard Omega2 wi-fi and Omega2 Plus wi-fi you can connect devices such as current sensors, temperature and humidity adapter I2C, accelerometer, LED display, gyroscope and others. Omega2 also has a built-in wi-fi module. Last minikomputer also has output pins for communication with external devices via I2C, SPI, UART, and generating the PWM signal.
