Technology is constantly evolving in two specific directions - the first one is to maximize equipment performance and improve its parameters, the second one is to miniaturize components and systems. Onion IoT is a perfect example, it was launched in 2016 and since then it has become incredibly popular among minicomputer enthusiasts.
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.

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 with module GPS, which works with accuracy up to 1.8 m with 66 channels and a sensitivity of165 dBm. The update frequency is 10 Hz. The system communicates via USB port, it also requires a device type dock with a USB connector.
Extension for Onion Omega2 for communication of the minicomputer with Bluetooth 4.0 BLE. The device is in a form of a USB module, except for the Omega module it also requires the extension type Dock, for example, Power Dock or Mini Dock.
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.
Onion IoT is a crowdfunding project that started its history with a fundraising campaign on the popular Kickstarter website. It quickly gained popularity all over the world thanks to the fact that it is compatible with Linux system, which is very popular among programmers. Even the first version in 2016 was very well-received among the interested users. Due to the fundraising and monitoring the customer needs, the second edition of Onion Omega 2 and the Plus version provide all the components and interfaces that were missing in the initial design. It can be expected that the producer did not say the last word and they will constantly bring out new offers, modules, extensions and versions of the platform.
Not all systems require super-efficient computing power. In most cases, simple tasks need only a few sensors and controllers to, for example, open and close the gate after detecting the motion or the transmitter signal. In that case the use of Raspberry Pi or Arduino turns out to be quite an unprofitable idea as users will not even take advantage of the half of their potential. Fortunately, there is Onion IoT.
In this category you can find interesting modules and accessories that allow you to expand the capabilities and functionalities of Onion IoT. We offer such components as the NFC/RFID extension, PWM signal generators, universal boards, GPIO and USB boards, displays and many others. Onion IoT definitely deserves special attention as it is the smallest module that enables creating Internet of Things solutions in the world.
