EasyVR 3 Plus Shield for Arduino

Do you make time to talk to your Arduino? Maybe you should! The EasyVR 3 Plus Shield is a voice recognition shield for Arduino boards integrating an EasyVR module. This kit includes the EasyVR 3 Plus Module, the Arduino Shield Adapter, microphone, and headers. With all of these parts, everything has been provided to you to get up and running in a short amount of time with minimal soldering!

EasyVR 3 Plus is a multi-purpose speech recognition module designed to add versatile, robust and cost effective speech recognition capabilities to almost any application. The EasyVR 3 Plus module can be used with any host with a UART interface powered at 3.3V – 5V, such as PIC and Arduino boards. Some application examples include home automation, such as voice-controlled light switches, locks, curtains or kitchen appliances, or adding “hearing” to the most popular robots on the market.

Note: Please be aware that the EasyVR 3 Plus Shield for Arduino does not come pre-assembled and will require some soldering and assembly before operation.

  • Supports 5V and 3.3V main boards through the IOREF pin (defaults to 5V if this pin is absent)
  • Supports direct connection to the PC on main boards with a separate USB/Serial chip and a special software-driven “bridge mode” on boards with only native USB interface, for easy access and configuration with the EasyVR Commander
  • Enables different modes of serial connection and also flash updates to the embedded EasyVR module (through the Mode Jumper)
  • Supports remapping of serial pins used by the Shield (in SW mode)
  • Provides a 3.5mm audio output jack suitable for headphones or as a line out

EasyVR 3 Plus Shield for Arduino Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.
See all skill levels


Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels


Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
