International Black Friday and Cyber Monday 2023 deals and coupon codes

We’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, as US-centric promotions such as Amazon’s Black Friday and Cyber Monday deals are not always available to the international audience of CNX Software. So once again, we’ve searched at Black Friday and Cyber Monday 2023 international promotions and discount codes from specific manufacturers as well as popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress will have a Black Friday (and Cyber Monday) event in 2023, but we have limited details at this time since it will only start on November 23, contrary to some of the other deals we’ll feature below which are already up and running. But the event will have two periods: Nov 20-22 PT – Warm Up event where users can find and add items to the cart before purchasing during the […]

AMD Ryzen Embedded 7000 Zen 4 SoC integrates Radeon RDNA 2 graphics, up to 28 lanes of PCIe 5 connectivity

AMD Ryzen Embedded 7000 Series is a new “Zen 4” processor with integrated Radeon RDNA 2 graphics designed for high-performance embedded systems targetting industrial automation, machine vision, robotics, and edge servers. The last two Ryzen Embedded families from AMD, namely the Ryzen Embedded V3000 and Ryzen Embedded 5000, mostly targeted headless networking and storage applications since the processors lacked any 3D GPU. But the new Ryzen Embedded 7000 processors bring back graphics with a Radeon RDNA 2 GPU clocked at up to 2.2 GHz and also come with up to 12 Zen4 cores clocked at up to 5.4 GHz, and feature up to 28 lanes of PCIe 5 connectivity. Ryzen Embedded 7000 Series specifications: CPU – Up to 12-core/24-thread “Zen 4” processor GPU – Radeon RDNA 2 graphics 1WGP @ 2.2GHz max with support for AV1/VP9 decode, H.264/HEVC decode/cncode Cache – Up to 1MB L2 cache/Core, up to 32MB L3 […]

Ubuntu Touch 20.04 OTA-3 release adds support for PinePhone and PineTab devices

UBPorts has just released Ubuntu Touch 20.04 OTA-3 based on Ubuntu 20.04 LTS with the latest security updates and beta support for PinePhone, PinePhone Pro, PineTab, and PineTab 2, adding to the smartphones already supported by Ubuntu Touch 20.04 OTA-2. As a reminder, Ubuntu Touch was initially handled by Canonical for desktop/mobile convergence, but it was dropped when the company decided to refocus its efforts on cloud and IoT, and the UBPorts community took over and eventually outed the first stable Ubuntu Touch release in June 2017. The developers kept on improving the OS since then with new releases from time to time, but note that it should still be considered experimental only for most devices, and will not be suitable as a daily driver for the majority of people. The PinePhone and PineTab have been supported by Ubuntu Touch for a few years, but they had their own branch […]

Giveaway Week 2023 – WCH CH583M-R0 development board and some RISC-V microcontrollers

Early this year, WCH sent me a few of their RISC-V MCU boards and chips to thank me for writing about their products. I gave one for review with some chips but it went to review heaven, or in other words, no review was ever written. I also sold a couple locally, and since I don’t think I’ll ever have time for a review, we are now giving away the remaining boards and chips here and on CNX Software Thailand. Today’s giveaway is the WCH CH583M-R0-1v1 board, also known as CH583EVT or CH583M-EVT-R0, based on the CH583 RISC-V Bluetooth 5.3 LE microcontroller that exposes all I/Os from the chip, a few buttons, and USB ports, and also features an SWD/UART header for debugging. You’ll find the documentation, code samples, an Android app and other resources to get started on GitHub. I’ll also throw all the remaining chips I have left […]

ESP32 Arduino Core 3.0.0 adds support for ESP32-C6 and ESP32-H2

Espressif Systems has now released an alpha version of ESP32 Arduino Core 3.0.0 enabling the new ESP32-C6 and ESP32-H2 targets to be programmed with the Arduino IDE, and including a number of new features made possible by the ESP-IDF 5.1 SDK. Announced in 2021, the ESP32-C6 WiFi 6, Bluetooth 5 LE, and 802.15.4 wireless MCU became available in modules and devkits at the beginning of this year, but so far they could only be programmed with the latest version (5.1) of the ESP-IDF framework, and so was the new ESP32-H2 Bluetooth 5.2 and 802.15.4 (Zigbee/Thread) MCU. But fans of Arduino programming can now rejoice as an alpha version of ESP32 Arduino Core 3.0.0 brings support for the new microcontroller, and a stable release is planned for December 2023. But as you can probably imagine ESP32 Arduino Core 3.0.0 will also bring lots of other changes since the ESP32 Arduino Core […]

$150 BeagleV-Fire SBC features Microchip PolarFire RISC-V SoC FPGA, supports BeagleBone capes

BeagleV-Fire is a new single board computer powered by Microchip PolarFire MPFS025T penta-core RISC-V SoC FPGA that follows the BeagleBone Black form factor for compatibility with BeagleBone capes expansion boards. Microchip PolarFire RISC-V SoC FPGA was one of the first Linux-compatible RISC-V SoCs and was found in pricey boards such as the Icicle and TySOM-M-MPFS250 development boards. I also got an Icicle board for review, and while getting started with the Yocto Linux BSP was OK, I really struggled with the FPGA part including just installing Libero SoC in Ubuntu and going through the license, and even I gave up trying to run a bitstream sample on the board due to a lack of time. The BeagleV-Fire makes it much cheaper to try out the PolarFire and hopefully makes it easier to get started with both Linux and the FPGA fabric through easier-to-understand documentation and code samples. BeagleFire-V specifications: SoC […]
