Product description: RedBoard SparkFun - compatible with Arduino
RedBoard is fully compatible with the popularArduino Unomodule. It means that it can be programmed throughArduino IDE environmentusing available libraries. Overlays, so calledArduino Shieldwill also work with SparkFun module.
The overlay combines the simplicity of ArduinoUnowith the stability of communication of FTDI series circuits. On board is Atmega328 microcontroller with Arduino Uno compliant output distribution. The changes that can be seen while using the module are:
- MiniUSB connector - large USB B connector has been replaced by small comfortable miniUSB socket
- FTDI system - a proven and stable FT232 module has been used to communicate with a computer
- The colour of the tile has been changed from blue to red

To start the Redboard, connect the system to your computer with aminiUSB cableand installFTDI drivers. Then inArduino IDE environmentselect Arduino Uno board. |
Power supply .
The module can be powered viaa miniUSB cable andan external device, e.g. mains adapter, battery or rechargeable battery. The power supply is switched automatically. The power supply is connected to a standard DC socket. The battery or other source is connected to the POWER connector pins.
Programming
Creation and installation of the softwareenables free environmentprovided by the manufacturer. Implemented bootloader allows you to upload the program directly throughthe miniUSB cable.ISCP connector allows to connect externalAVR programmer. Detailed description can be found indocumentation and tutorial.

Arduino Uno vs. RedBoard
| Similarities | Differences |
| Atmega328 - both boards have the same popular main microcontroller. | USB connector - Arduino Uno uses a large USB B connector, while SparkFan has placed a miniUSB connector on its board. |
|
PCB selection in Arduino environment - for both chips in options you should choose Uno module. |
USB - UART converter - Uno has Atmega16u4 chip with appropriate software, on RedBoard there is dedicated FTDI FT232 chip. |
|
Digital and analog pins - both boards have the same number of outputs, distributed in the same way. |
The Arduino board is made in THT threaded technology, RedBoard is made in SMD - surface soldered. |
|
Operating voltage - both modules work with 5V and have a built-in voltage regulator 3.3V. |
The RedBoard module is in red, Arduino has a blue color. |
Examples of accessories
- Gyroscope, accelerometers, IMU- sensors type MEMS with digital output (I2C bus)
- Displays -LCD screens where data can be easily displayed
- Optical sensors- rangefinders, colour sensors, optocouplers
- Gas sensors -systems for detecting methane or alcohol concentrations
- DC motor controllers -systems for regulating the direction and speed of motors
- Steppermotors controllers - modules allowing to control the position of stepper motors
