What Is The RedBoard?is one of the most popular physical computing platforms available today. It's an amazing tool for both experienced and budding electronics enthusiasts. It's part hardware, part software, and part community; all of which come together to create a well-supported, solidly-designed electronics platform.The best part: the entire Arduino project - both hardware and software - is open-source. The, hardware design files, and are all freely available for viewing and modification.
Program telewizyjny do wydruku kolorowanki. Released under a, anyone is free to riff on the hardware design and produce their own version. That's what we've done with the.
It still looks and acts just like an, but is slightly modified to make the board better-suited to our purposes. An (left, blue) next to a.Our glosses over some of what makes the RedBoard different from the Arduino Uno:ReplaceMeOpenReplaceMeCloseIn this tutorial, we'll take an in-depth look at the major similarities and differences between the two boards. Stated briefly, here's the key info: Key Differences. USB connector: Arduino Uno uses a USB type B connector, while the Redboard uses the smaller mini-B connector. Each connector requires a different USB cable. USB-to-Serial Transciever: The Arduino Uno uses an ATmega16U2 loaded with custom firmware to convert between USB and serial. The RedBoard uses the FTDI FT231X.
This difference is only really prevalent when installing drivers because each requires a different driver file. SMD vs PTH: The Arduino Uno comes in two versions through-hole (PTH) or surface-mount (SMD). The RedBoard is only offered in SMD.
The RedBoard takes this a step further, by making every component surface-mount. No sharp edges on the bottom of the board!. Color: It won't have any real influence on the operation of the Arduino, but it certainly affects the board's swag-factor. Cool blue or Ferarri SparkFun red?. Price: Because we manufacture the board in-house, here in Boulder, CO, we can afford to keep the price-tag a tad lower.Key Similarities. ATmega328: The main microprocessor on both boards is the popular ATmega328.
Arduino Single-sided Serial Board Bootloader Instructions
This is they key-est of similarities. IDE interaction/Board Selection Type: The ATmega328 on both boards is loaded with the same bootloader (Optiboot). That means, when you program the board, you can still select Arduino Uno under the Tools Board menu.
Dimensions and Connector Layout: Both boards are the same size and shape, and the female header connectors are all placed in the same locations. All shields and enclosures will be compatible with both boards. Digital and Analog Pins: Each board has 14 digital I/Os and 6 analog I/Os.
Operating Voltage: Both boards operate at 5V, and have an on-board 3.3V regulator. They can be powered either through USB or with a 7-15V barrel jack power supply.
Compare and ContrastThe RedBoard, Arduino Uno SMD, and Arduino Uno PTH have a lot in common. They really share more similarities than they do differences. Obviously, you'll need a cable that matches the connector on the development board. The Arduino Uno would require an cable, while a RedBoard would require an cable (or you could cover both bases with a ). USB-to-Serial ConverterThe second difference between the boards is how they manage to convert USB coming from your computer into a the Arduino can understand. Arduino serial communication is critical for uploading sketches and sending/receiving information via the Serial Monitor.
The Uno uses an Atmel processor - the ATmega16U2 - loaded with custom firmware, to convert USB to (and from) serial.Before the Arduino Uno was released of the development platfurm used a dedicated USB-to-serial transceiver: FTDI's FT232RL. Call us nostalgic, but we really preferred the robust reliability of the FT232RL over the ATmega16U2 solution. So when we designed our own version of the Arduino platform, we decided to revert back to the FT232RL for our USB-to-serial needs.About 99% of the time these ICs should be of no concern to your everyday Arduino hacking.
Once drivers are installed, each should transparently convert data between your Arduino and computer. The difference between the two USB/Serial transceivers is most apparent when you're first connecting the board to your computer.
USB Driver InstallationFor Windows users in particular, each board requires a unique driver to be installed before being usable. There are plenty of installation tutorials for both chips ( and ).The most up-to-date version of the FTDI drivers can be downloaded directly from the where they host of their own.
There should be no shortage of driver-installation support out there.Once the board is connected to your computer and the drivers are installed, the two chips should be almost invisible. For the most part, we don't really care how the Arduino communicates with our computer, just that it does. An SMD Arduino Uno (left) and the regular PTH version.
The ATmega328 processors are highlighted on each board, they look different, but are actually (pretty much) the same thing.The RedBoard is only offered in one form: surface mount. The design actually takes the SMD choice even further by making every component SMD (the Arduino UNO SMD still has PTH connectors, for example), but the main focus of the SMD vs. PTH debate centers around the package of the microcontroller (as highlighted in the image above). SMD Pros and Cons Pros: No Snags, Lower CostThe absence of PTH components on the RedBoard means a nice, smooth surface on the bottom of the board - there's no danger of being pricked by pointy solder joints. On top of that, eliminating exposed joints on the bottom of the board also protects the components from accidental shorts.
As any hobbyist with a messy desk could attest, stray wire clippings and other metals strewn across workbenches are a common source of accidental. Or will help prevent against this if you're using an Arduino board. Con: Hard to Swap µCsMicrocontrollers (µCs) - in this case the ATmega328 - are usually the most expensive component in a design. A µC failure is hard to overcome, and it usually requires either replacing the component or just recycling the board.The nice thing about the PTH Arduino is the ATmega328 is socketed, so if it blows up replacing the chip is as easy as prying it out and sticking in a.The ability to easily remove the ATmega328 has other advantages as well. For example, if you're looking to build a project using the IC, you can prototype in the development board and eventually transfer the microcontroller out of the Uno to a custom board.: Microcontroller failure on all of these boards is a big 'if'. The ATmega328 is a very resilient microcontroller. You really have to try to fry the IC, or even just a single I/O pin on it.
A failure in the power circuitry (voltage regulators specifically) is much more likely. Resources and Going FurtherNow that you feel comfortable with your development board selection and the advantages and disadvantages that go with it, it's time to explore the world of Arduino!Here's a few simple tutorials to get you started:.And here's some more advanced tutorials, if you're ready to take on more of the Arduino world!.ResourcesFor more information on the SparkFun Redboard, check out our.

Though they're included with Arduino installs, this is where you'll find the most up-to-date FTDI VCP drivers. A video introduction of the RedBoard. In 2003, CU student Nate Seidle fried a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own company. Since then, SparkFun has been committed to sustainably helping our world achieve electronics literacy from our headquarters in Boulder, Colorado.No matter your vision, SparkFun's products and resources are designed to make the world of electronics more accessible.
