Offline voice recognition module supports Arduino programming, custom voice commands

Offline Voice Recognition Arduino

We’ve already covered inexpensive offline voice recognition modules based on US516P6 or TW-ASR ONE microcontrollers that allow people to add smarts to their projects without a network connection for improved privacy and lower latency. Those are great in theory, but at the time (April 2022) documentation was lacking or only in Chinese, and they were fairly hard to use based on some of the comments in my earlier posts. But today, I’ve noticed DFRobot is now selling the “Gravity: Offline Voice Recognition Sensor – I2C & UART” module with support for Arduino programming, and it looks fairly easy to customize as we’ll see further below. Gravity Voice Recognition DF2301QG module specifications: Voice recognition module – WS-2520-TR module with MCU – TBD 121 commonly used fixed voice commands, one-fixed wake word Support for 1 learned wake-word, 17 user-defined commands Audio Output – Built-in speaker and external speaker interface Input – Dual […]

AMD Ryzen Embedded 5000 processors launched for networking applications

AMD Ryzen Embedded 5000

We first spotted the AMD Ryzen Embedded 5000 processors in a micro-ATX motherboard last August, but AMD has now only announced the availability the of Ryzen Embedded 5000 Series “Zen 3” processors designed for  “always on” networking firewalls, network-attached storage systems, and other security applications. AMD also mentions the Ryzen Embedded 5000 are “power-efficient processors”, but that does not mean low power, as those embedded processors are 65 to 105W parts, and offer a step-up in performance from the 10 to 54W AMD Ryzen Embedded V3000 processors also targetting networking and storage applications. As we found out last year, four SKUs are available with the Ryzen 5950E, Ryzen 5900E, Ryzen 5800E, and Ryzen 5600E, but the specifications are a little different, as for instance, there’s no 10-core part. All four are AM4-socket processors, support two DDR4 channels up to 3200MT/s, and come with 24 PCIe Gen4 lanes, and when optionally […]

GEEKOM AS 6 AMD Ryzen 6000 mini PC takes on Intel NUC 13 Pro “Arena Canyon” (Sponsored)

GEEKOM AS 6 mini PC powered by ASUS

GEEKOM AS 6 is an AMD Ryzen 6000 mini PC developed in collaboration with ASUS that aims to provide a cost-effective alternative to the Intel NUC 13 Arena Canyon mini PC powered by an Intel Core i7-1360P Raptor Lake-P hybrid SoC. The mini PC is equipped with either an AMD Ryzen 9 6900HX or Ryzen 7 6800H processor, supports up to 64GB DDR5 memory, three storage options with two NVMe sockets and one 2.5-inch SATA drive bay, and can drive up to four independent displays thanks to two HDMI 2.1 ports, one DisplayPort 1.4 output, and two Thunderbolt 4 / USB4 ports. Networking is the same as on the NUC with 2.5GbE, WiFi 6E, and Bluetooth 5.2. Here’s how GEEKOM AS 6 specifications compare the ones of the Intel NUC 13 Pro “Arena Canyon”. The performance of the selected AMD Ryzen 9 and Intel Raptor Lake processor is comparable, but […]

100ASK-V853-Pro – A feature-rich Allwinner V853 board designed for AI vision applications

100ASK V853 Pro

The 100ASK-V853-Pro board is a development kit consisting of an Allwinner V853 system-on-module board (SoM) and a feature-rich carrier board with a large number of interfaces. Allwinner V853 supports up to 1TOPS of NPU computing power and is mainly for AI vision application development. The core board contains a DDR and eMMC as well as a PMU chip (AXP2101) and is connected to the carrier board through a board-to-board connector. All the functional resources of the V853 are drawn out through the carrier board. The carrier board comes with 2-channels CSI camera interfaces as well as RGB and MIPI DSI display interfaces. Although 1 TOPS of AI computing power is not outstanding, the NPU can still be used to accelerate AI vision applications at the edge. The board also comes with four USB 2.0 ports (two Type-A, two Type-C), an 100Mbps Ethernet port, a 22-pin header for expansion, and five […]

AAEON BOXER-8224AI – An NVIDIA Jetson Nano AI Edge embedded system for drones

BOXER 8224AI board AI Edge NVIDIA Jetson Nano embedded system

AAEON BOXER-8224AI is a thin and lightweight AI edge embedded system solution based on NVIDIA Jetson Nano system-on-module and designed for drones, or other space-constrained applications such as robotics. AAEON BOXER products are usually Embedded Box PCs with an enclosure, but the BOXER-8224AI is quite different as it’s a compact and 22mm thin board with MIPI CSI interfaces designed to add computer vision capability to unmanned areal vehicles (UAV), as well as several wafers for dual GbE, USB, and other I/Os.

EVerest is an open-source software stack for car charging stations

EVerest open source car charging station software

EVerest is a software project initiated by PIONIX GmbH, but now part of the Linux Foundation’s LFEnergy initiative, whose primary goal is to develop and maintain an open-source software stack for EV charging infrastructure. EVerest supports multiple standards and it will run on any device from AC home chargers to public DC charging stations. I noticed the EVerest project in an upcoming talk at the Embedded Open Source Summit 2023 entitled ” EVerest: Electric Vehicle Chargers With Open Hardware and Software” and whose abstract reads in part: You will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open-source software stack for EV charging infrastructure. Following a quick introduction to EV charging technology, with explanations of the standards, protocols, and complexities involved, the talk will go into a deep dive into how you can build your own AC charging station.
