Almost every day a new single board computer announced the birth. The so-called “Raspberry Pi effect” has been on the use of this circuit board had a huge impact. Although Raspberry Pi no doubt improves the interests of small computer, only the most important part, this is by no means a single unique case. There are many other circuit boards that have been around for years. On the market, Arduino may be the most famous. It may be licensed to design a small computer board mostly. Among them, Raspberry Pi and Arduino are the most popular available single board computers. From the refrigerator network server to the automatic remote four-axis aircraft, they exist in thousands of projects made by “manufacturers” or electronics enthusiasts. The range of open-source ecosystems for Arduino micro-controller-based projects, source code and expansion boards (called “shields”) is staggering. The adoption of Raspberry Pi will be rapid growth. Using ARM-based microprocessors and Linux operating systems, the incubation projects and application software is completely different from Arduino.

Single board computers are certainly not new ideas. Semiconductor manufacturers have been selling single board computers for years,

As a way to mitigate the adoption of the latest micro controller devices and provide a low-cost evaluation platform equipped with a variety of peripherals and IO, and embedded developers can carry out their new design according to them.

G4418 SBC is an example of such a development board by Graperain in 2015 for embedded development students to learn based on South Korea’s Samsung S5P4418 chip system (SoC) open source hardware and software development and design. Subsequent circuit board iteration, the credit card size of the G4418 SBC quickly joined Arduino and Raspberry Pi ranks, as a strong competitor.

There is no doubt that these three circuit boards can and will continue to be used for electronic theoretical teaching, enthusiast construction projects, so professional embedded developers can use them as a new commercial design basis?

Raspberry Pi

Raspberry Pi is the main source of near-term profit for single board computers. Originally intended for college students, Pi has proven to be a long-time favorite because of its wider community spectrum. Primary schools, Boy Scouts groups and manufacturers have found applications for Raspberry Pi. From a technical point of view, Pi and BeagleBone Black have more in common than Arduino. According to the Broadcom BCM2835 SoC, it has an ARM1176 MPU core running at 700 Mhz and is equipped with 512 megabytes of RAM. You will need to install a 4GB or larger SD RAM card. Different Linux distributions, such as Fedora, Debian, and Raspian can be used with Raspberry Pi, but be aware that they are not preloaded for BeagleBone Black. Although a factor can not affect professional developers, but for a hobby builder, you may initially find this is a cowardly process. Built-in USB, Ethernet, HDMI and composite video output Pi connectivity titles. In addition to SPI, I2C and power, a separate expansion pin can also access GPIO.

Arduino

First of all, Arduino is not just a circuit board. It represents a collection of circuit boards. All but one of the boards are based on Atmel’s well-supported and popular Atmel family of 8-bit AVR-based microcontrollers, and the Arduino family is ideal for a variety of sizes, IO and memory Configuration. Uno in the series (Arduino refers to the reference design) is the most popular circuit board, and use the Atmel ATmega328 device running at 16MHz. IO includes six analog inputs, 14 digital I / O, of which six can be used as PWM. Microcontrollers (MCUs) provide 1kB of electrically erasable read-only memory (EEPROM), 2kB of static random access memory (SRAM), and 32kB Flash memory. Arduino Due is based on Atmel’s SAM3X8E 32-bit Cortex-M3 microprocessor. The improved IO provides 54 digital IOs, of which 12 provide PWM outputs, 12 provide analog inputs, and 2 provide analog outputs. 512kB of flash memory can be used with a total of 96kB of SRAM. Recorded at a frequency of 84 MHz, that is, at the fastest speed of all Arduino boards.

Graperain G4418 SBC

Graperain G4418 SBC is a relatively new product. As part of a community support development platform for embedded developers and ‘manufacturers’, it claims to be able to launch Android in 20 seconds. Can quickly distinguish G4418 SBC and Arduino completely different, and more powerful.

The G4418 SBC uses the Samsung S5P4418 1.4GHz 32-bit ARM Cortex-A9 application processor, instead of being part of a single family. The circuit board has 1G bytes of DDR3 and 8GB of eMMC. Equipped with a 3D graphics accelerator. G4418 SBC will look to the higher performance of the application. Connections include USB, Ethernet, and HDMI, WIFI/BT, TF card upgrade etc..G4418 SBC is good at software support. Connect only to the power and screen, G4418 SBC can start pre-loaded Linux + qt, Ubuntu or Android. All hardware design files are available under an open source license.

Each board under review provides professional developers with an opportunity to accelerate new project design and prototyping phases. The choice of programming language, IO requirements and applications, as well as the developer’s own skill set will greatly affect the choice of circuit board. If a large number of sensors are used to start a new IO design, developers without this experience can consider providing better IO tutorials and support for circuit boards. Whichever board you choose, the developer should be able to make sure that the circuit board used is much more available to other engineers through access to expert forums, which is much easier than starting a new design entirely from scratch.
