Mcuzone RK3308 SoM and MDK3308-EK Evaluation Kit are Designed for Smart Voice Applications

Mcuzone MDK3308-EK Rockchip-RK3308 Development Board

Rockchip RK3308 is a quad-core Cortex-A35 processor that was announced in 2018 together with RK3326 specifically for Smart AI solutions. While the processor is equipped with an RGB LCD output interface, it does not come with a 2D or 3D graphics accelerator, so it’s better suited to smart speakers with an optional display using a basic user interface. I’ve not seen many hardware platforms or boards based on the processor, but today I noticed “Hangzhou Wild Chip Tech” had an RK3308 system-on-module, as well as development kits for sale on Aliexpress with the module price starting at $23. Mcuzone MDK3308 Coreboard Specifications: SoC – Rockchip RK3308 quad-core Cortex-A35 processor @ 1.3 GHz with NEON and VFPv4 FPU System memory / storage configurations: 256MB DDR3/3L + 256MB NAND flash 512MB DDR3/3L + 8GB eMMC flash 2x 100-pin dual row headers (1.27mm pitch) exposing: Display – LCD interface up to 1024×600 (RGB), […]

Volumio Motivo is a Gorgeous Audio Streamer Powered by SOPINE A64 SoM

Volumio is a well-known Linux based open source music player for Raspberry Pi, UDOO, Cubox-I, Beaglebone Black, and other single board computers. Some companies even made audiophile boards with support for Volumio including Khadas Tone high-resolution audio board for VIM/VIM2 SBC’s, and the tiny VoltaStream ZERO following Raspberry Pi Zero form factor. But Volumio team has decided to make their own hardware with Motivo, an awesomely looking audio streamer designed in collaboration with Yottamusic engineering firm, and Design Narratives industrial design company. Motivo was introduced at High-End Munich, the world’s biggest Hi-Fi trade fair, and Pine64 posted some photos in a tweet claiming it was powered by their SOPINE A64 system-on-module. The full details about the device have not been published at the time of writing, but we can still derive some of Volumio Motivo specifications and key features from the photos and a few bits of public information: System-on-Module […]

Grove AI HAT Helps Raspberry Pi Run Edge Computing Workloads

Last year we wrote about Kendryte K210 dual core RISC-V processor specifically designed for for machine vision and machine hearing as well as the corresponding Kendryte KD233 which enables inference at the edge, e.g. tasks such as face recognition or object detection. Latter on we found the processor in Sipeed M1 module which went for as low as $5 in a crowdfunding campaign, and was fitted to some low cost boards now selling for $12.90 on Seeed Studio. The latter company has now designed Grove AI HAT that aims to assist Raspberry Pi in running the edge computing workloads previously described, as exposes 6 Grove interfaces to extend functionality with some of the Grove add-on modules. Grove AI HAT specifications: AI Module – Sipeed “MAIX” M1 with Kendryte K210 dual core RISC-V processor @ 600 MHz, KPU Convolutional Neural Network (CNN) hardware accelerator, APU audio hardware accelerator, 8 MB general […]

Pico-ITX i.MX8M Board Enables Offline Voice Control with Snips

A few days ago, we covered Estone Technology’s MJ-100 RK3399 rugged tablet. I’ve just realized Estone Technology used to promote their embedded product under the Habey USA brand, which we covered a few times here, and the company has also announced another new product ahead of Embedded World 2019 with their EMB-2238 Pico-ITX i.MX8M board specifically designed for voice control applications. The company setup two voice control demos with the board: one with Amazon Alexa Voice Service (AVS) and another with Snips that works locally without any Internet connection. We actually came across Snips previously for an article comparing microphone arrays, but I never looked into Snips into details or saw an actual demo. Let’s have a quick look at EMB-2238 board specifications first: SoC – NXP i.MX 8MQuad with 4x Arm Cortex-A53 cores @ 1.5GHz, 1x Arm Cortex-M4 realtime-core @ 266MHz, Vivante GC7000L/GC7000LVX with support for OpenGL/ES 3.1, OpenGL […]
