Fortebit EasyVR 3 Plus Shield for Arduino

Fortebit EasyVR 3 Plus Shield for Arduino is compatible with any Arduino board and comes with the EasyVR 3 Plus module and the Arduino Shield adapter. The EasyVR 3 Plus is a multi-purpose speech recognition module designed to easily add versatile, robust, and cost-effective speech recognition capabilities to applications. The module can be used with any host with a UART interface powered at 3.3V to 5V, such as PIC and Arduino boards. Suitable applications include home automation, such as voice-controlled light switches, locks, curtains, and kitchen appliances, as well as adding "hearing" to robots. The Fortebit EasyVR Shield 3 is an adapter board for the EasyVR 3 module, designed to simplify its use among the Arduino community.

Features

Compatible with any Arduino board using UNO-R3 Shield headers, running at 3.3V or 5V, by using IOREF pin to select EasyVR operating voltage
Backward compatible with earlier Arduino boards without IOREF pin and are using 5V I/O levels by default
If board does not have IOREF pin but is running at 3.3V, users can still operate EasyVR Shield 3 via modifications
Board comes with separate Arduino stackable headers for the Shield interface (EasyVR 3 module is also provided separately)
Supports 5V and 3.3V mainboards through the IOREF pin
Supports direct connection to PCs on mainboards with separate USB/Serial chip and software-driven bridge mode on boards with only native USB interface, for easy access by EasyVR Commander

Enables different modes of serial connection and also flash updates to embedded EasyVR module (through mode jumper)
Supports remapping of serial pins used by Shield (in SW mode)
Provides 3.5mm audio output jack suitable for headphones or as line out
Compatible with Arduino boards that have 1.0 Shield interface (UNO R3) and legacy boards including, but not limited to:
- Arduino Duemilanove
- Arduino Uno
- Arduino Mega
- Arduino Leonardo
- Arduino Due
