Estone technology is proud to announce the new addition to our pico-ITX embedded board family – EMB-2238, an NXP i.MX8M based single board computer. Building upon the success of our i.MX6 board series. The EMB-2238 is our first embedded board to integrated with hardware DSP specially designed for voice control applications, This Quad core ARM Cortex-A53 board takes the advantage of NXP’s latest i.MX8M application processor with up to 15-year longevity, advance audio and 4K video supports. It is ready for ODM and industrial product designs for the fast-growing edge computing, voice human machine interface (HMI), streaming multimedia, and machine learning applications.
Targeting embedded and IoT applications with voice control, advance audio and display requirements, the EMB-2238 features a PoE (Power over Ethernet) ready GbE port, rich I/O options including RS-232/485 and USB 3.0, over 20 channels of high performance digital audio input and output expansion and dual core hardware DSP for voice-control algorithms. The board also features a 4-lane MIPI DSI and CSI and built in I2C touch panel support for all types of touchscreen applications. A 40-pin expansion header supports PCIe, GPIO, I2C, serial communications and a wide range of expansion options.
The voice control and audio support of the board is where the EMB-2238 truly stands apart. The on-board smart codec provides support for Dual Digital MEMS Microphone inputs, dual-core DSP with multi-mic noise suppression, Automatic Speech Recognition (ASR) enhancement, acoustic echo cancellation (AEC) and barge-in technology enable voice commands for during loud music playback., functions. 16 channel digital audio inputs and 10 channel digital audio outputs support microphone array expansion for voice and best in class audio with 32-bit 384KHz at each channel. BSP supports include Embedded Linux, Android, Qt, Wayland, Amazon AVS (Alexa Voice Service) Device SDK, Sensory TrulyHandsfree Wake Word Engine, and offline Automatic Speech Recognition (ASR), and Natural Language Understanding (NLU) engine, like the Snips AI voice control platform.
