[Arduino] Open Source Development Board description

New microcontroller types from all over the world emerge one after another. Most of these development boards use Arduino-improved versions, such as y ún, Which is improved by Arduino, it mainly improves or upgrades other wireless functions for the mesh network.

 

However, some development boards have their own unique designs and basic function upgrades. Here we will take a look at these new partners that have been produced or are about to be put into the market ".

 

Products in various fields, including SMART toys, game peripherals, home and industrial automation, consumer medical devices, printers, smart vending machines, and educational Terminals, its prototype and finished product may be born from the following development boards.

 

1. Arduino yún

 

Arduino yún is a WiFi-enabled microcontroller based on Arduino Leonardo (atmega32u4) and an independent embedded ar9331 processor. It is also the first member of the Arduino family in the WiFi system.

 

 

We can remotely design and program through WiFi connections, or perform operations through general USB connections.

 

In addition, Arduino has also partnered with temboo to use one-stop APIs to access information from Twitter, Facebook, Foursquare, FedEx, PayPal, and more websites.

 

The price of this board is $69, considering the cost of integrating embedded Linux devices, Arduino and WiFi transmitters, and other Expansion Boards into one Development Board, this price suits the psychological price of most of us.

 

2. beaglebone black

 

Beaglebone blackbeaglebone black is one of the few Linux development boards that can be started in 10 seconds. Its size is 8.6x5.3, which is only the size of a credit card.

 

 

Beaglebone black uses Texas Instrument's 1 GHz arm Cortex-A8 processor, plus 2 GB emmc storage, MB ddr3 memory, and a scalable storage microSD card slot.

 

The Board has a 46pin slot on both sides. It supports LCD interface, UART interface, emmc interface, ADC interface, IIC interface, SPI interface, and PWM interface to connect different external devices. In addition, it is equipped with a Micro HDMI, a usb otg, a USB host interface, and an Ethernet interface.

 

At present, the most satisfactory thing is that the black price is only 35 US dollars, which is greatly lower than the previous generation of products.

 

3. udoo

 

Like Raspberry Pi, udoo is a Linux board with an ARM architecture, and a second ARM processor is installed on the board to simulate Arduino due.

 

 

Udoo has dual-core and quad-core arm cortex-A9 CPUs, using the same arm sam3x processor as Arduino due. Udoo also has built-in OpenGL accelerators, 54-bit I/O, and analog input (pinout compatible with Arduino R3), Ethernet, built-in WiFi, HDMI, USB, SATA, and analog sound signals.

 

However, such a powerful configuration makes this board unique. In addition, the price of the quad-core version is more than 129 USD, and it is difficult to find a reasonable position.

 

4. Goldilocks

 

Goldilocks is a very interesting and unique development board. As an Arduino secondary edition, it neither uses the UNO atmega328p nor the mega atmega2560, but uses the atmega1284p microcontroller.

 

 

Goldilocks is similar to UNO, but SRAM is eight times larger than the latter.

 

If your sketch design on the Arduino uno has challenged the limits of the SRAM, you can find some fun on this board, although compared with the existing Arduino Development Board, $45 is not cheap.

 

5. digix

 

Digix is a development board compatible with Arduino due. It has a built-in low-power WiFi (B/G/N) and a network with the nrf24l01 architecture. It has up to 99 I/O pins.

 

In addition, digix has a real-time clock and 4 x uarts, 2 x I2C, SPI, CAN bus, 2 x DAC, JTAG, and DMA.

 

 

In terms of functionality, digix seems to be trying to meet everyone's needs, with a level-shifting SHIELD added for shipment.

 

The current digix retail price is $59, which is very attractive.

 

6. Uruk

 

Uruk and Arduino yún have some similarities. If you don't check that it has an Arduino-compatible MCU (atmega32u4) built in, it is just like a familiar wireless router.

 

As a Wi-Fi module connected to Arduino, Uruk also has a built-in firewall, which can effectively improve the security of network connections.

 

 

Uruk's design concept is very interesting and can be set directly on the browser webpage. However, its funding on KickStarter is not very smooth, and the rest of the week is, we hope it can be successfully launched.

 

The current price of this development board is $39. If you only need an extended module of Arduino, you can select another version of $29.

 

7. sparkcore

 

Sparkcore is a platform with supporting cloud services. It is compatible with Arduino and has built-in WiFi functions.

 

 

Like yún, sparkcore can also be connected through WiFi for program development. In addition to the wireless LAN, sparkcore can also access and update its progress from anywhere through cloud services.

 

Currently, sparkcore is priced at $39. With its functions and services, it has a bright future.

 

8. extracore

 

Extracore is a very small (22mm × 25.4mm, weighing only 1.7 grams) Development Board that is compatible with Arduino and has 22 I/O pins. We can foresee that most people who choose extracore for development and design are aiming at its specifications and sizes and low costs.

 

 

The price of extracore is only $15. Although this price is not enough for us to treat it as a consumable, it is a good choice to design some one-time prototypes.

 

9. digispark

 

Digispark is also a development board based on the attiny85 architecture and is small enough to support Arduino ide 1.0 + (OSX/win/Linux ).

 

 

Digispark has only six I/O pins, but it can be extended using a variety of expansion tools. Digispark is only priced at $12, which is a good choice for beginners of development and function expansion.

 

10. pc.pdf

 

Pcduino can run a complete PC operating system, such as Ubuntu and Android ics. It is also easy to use toolchain and compatible with the open ecosystem of Arduino, including Arduino shield and open-source projects.

 

It is worth noting that it is compatible with most of the Arduino Expansion Boards, and all the Arduino expansion pins can be accessed through APIS, including UART, ADC, PWM, gpio, I2C.

 

 

Just like Arduino, we can directly write programs on pcsag and run them directly. In addition, we can use some functional modules provided by sparkfun to Expand functions without driving them.

 

Based on the performance of pcduino, the price of $59.95 is a very attractive price.
