MATRIX Creator and MATRIX Voice For Raspberry Pi

MATRIX Labs have now released a new Raspberry Pi accessory that combines a whole new level of sensors built into miniature computer. The MATRIX Creator – was built with an aim of giving every hobbyist, tinkerer, and hackers around the world a complete, affordable, and user friendly device for simple as well as complex Internet of Things creation.

MATRIX Creator

The MATRIX Creator is an all-inclusive hardware device that connects to the GPIO pins on the Raspberry Pi and provides a means for any developer around the world to start making machine learning, computer vision, and Internet of Things applications within minutes,

MATRIX Creator is powered by a Xilinx Spartan 6 FPGA, a super powered miniature ARM Cortex M3 microcontroller, a collection of precise sensors for motion sensing, temperature, humidity, light, ultraviolet and infrared measurement, an 8-microphone array and a 35-LED array.

This board can be programmed in multiple languages in various levels. It employs Z-Wave and Zigbee protocols for wireless connectivity and a wide range of analogue and digital input/output interfaces.

MATRIX Voice

MATRIX Voice, on the other hand is a smaller board that mainly focuses on voice detection and recognition projects. In addition to its ability to connect with Raspberry Pi, it can also be used as a standalone module by taking advantage of its FPGA capabilities.

This little development board consist of a radial array of 8 MEMS microphones, 18 RGBW LED’s and 64 GPIO pins, which is linked to a Xilinx Spartan6 FPGA and 64 Mbit SDRAM. This provides the hobbyists and developers a wonderful opportunity to add custom voice and hardware-accelerated machine learning technology In no time.

An advanced version of this MATRIX Voice is also available employing a ESP32 Wi-Fi / BT chipset which will enable users to easily connect to the network or other devices via WiFi and Bluetooth in no time.

Size

MATRIX VOICE consist of a 3.14-inches in diameter development board with radial array of 8 MEMS microphones, with 18 RGBW LED’s connected to it. MATRIX Voice weighs 2 oz.
