Olimex RVPC is a one Euro RISC-V computer kit with VGA and PS/2 connectors

Olimex RVPC is one Euro RISC-V computer powered by a WCH CH32V003 RISC-V microcontroller and equipped with a VGA port for video output and a PS/2 connector to connect a keyboard. You won’t be able to do much with this device as an end-user, but it does not matter since the RVPC open-source hardware board mostly targets the education market and is offered as a kit to be soldered to lower the selling price and to serve as a soldering learning kit. Olimex RVPC specifications: MCU – WCH CH32V003 32-bit RISC-V2A microcontroller up to 48 MHz with 2KB SRAM, 16KB flash (SOP8 package with 6x GPIOs) Video Output – VGA connector (3x GPIO used for Vsync, HSync, and RGB) Keyboard port – PS/2 connector (2x GPIO used) Programmer port – 2-pin header for CH32V003 programming through a board such as ESP32-S2-DevKit-LiPo-USB Misc – Buzzer (1x GPIO) and Red power LED […]

Olimex VGA2HDMI is an open hardware board for VGA to HDMI conversion

Olimex VGA2HDMI is an open-source hardware VGA-to-HDMI converter specially designed and tested to work with the CERBERUS 2100, AgonLight 2, and Agon Origins boards. The board has a VGA port as input and an HDMI port as output and a USB-C port is there to provide the external power required for the board. In one of our previous posts, we wrote about the NovaVGA Shield, which adds VGA output to your Arduino UNO. Now, with the help of this board, that capability can be extended to HDMI. There are also extenders that carry VGA signals over Ethernet cables, a topic we have covered in another post. With this new board, you can convert that VGA signal to HDMI. It’s not like there aren’t other VGA to HDMI converters on the market; a quick Amazon search gave me the VENTION VGA to HDMI Adapter, but among them, most were HDMI to […]

Banana Pi BPI-KVM – A KVM over IP solution based on Rockchip RK3568 SoC

Banana Pi has started working on the BPI-KVM box based on a Rockchip RK3568 SoC, but it’s not a mini PC, and instead, it is a KVM over IP solution designed to remotely control another computer or device as if you were on-site with, for example, the ability to turn on and off the connected device, access the BIOS, and so on. Commercial KVM over IP solutions used to be expensive, but people have started to use Raspberry Pi SBCs with an expansion board such as the PiKVM v3, and more recently Raspberry Pi CM4-based KVM over IP solutions have been launched for under well $200. Seeing the popularity of these solutions, Banana Pi has decided to join the fray with its own BPI-KVM powered by an IO-rich Rockchip RK3568 processor that provides all interfaces needed for this type of application. Banana Pi BPI-KVM (preliminary) specifications: SoC – Rockchip RK3568 […]

Weibu N10 Review – An OEM Mini PC tested with Ubuntu 22.04, Windows 11

Weibu is a B2B company offering total solutions and OEM/ODM services. Their target clients are computer manufacturers like Acer and Hisense as they don’t sell directly to end users. With their products both the specifications and accessories can be customized according to their customer’s requirements. One of their product lines is mini PCs and they have sent a pre-production sample of their N10 design to showcase their capabilities. In this review, I will look at the various options available for the N10 and briefly look at performance running both Windows and Ubuntu. Weibu N10 hardware overview The key selling feature of this mini PC is the wide range of ports suitable for commercial/industrial usage together with various options for the processor. The N10 is an actively cooled mini PC and the device is 145 x 128 x 54mm (5.71 x 5.04 x 2.13 inches) large with a metal top that […]

x86 system-on-module features 1GHz DM&P Vortex86DX3 processor

DM&P Vortex86DX3 is an x86 embedded processor launched in 2015 that we’ve previously found in single board computers and mini PCs, but I’ve just noticed ICOP was offering the SOM304D3 system-on-module based on the single and dual-core versions of the Vortex86DX3 SoC. The SOM304D3 is available with 1 or 2GB DDR3 RAM, works in a wide temperature range (up to -40°C to +85°C), and is designed for space-constrained industrial applications, especially those requiring legacy interfaces like ISA, IDE, and/or a parallel port (aka printer port). SOM304D3 specifications: SoC – DM&P Vortex86DX3 single or dual-core x86 processor @ 1 GHz, 2D GPU System Memory – 1GB or 2GB DDR3 Storage – Optional 4GB eMMC flash; SPI flash for AMI BIOS 4x 76-pin board-to-board connectors: Storage – SATA 1.0, IDE, SD Display VGA up to 1920 x 1080 @ 60Hz TFT LCD up to 1024 x 768 @ 60Hz Audio – 1x […]

Your VGA monitor may be easier to repair than you think

When a VGA monitor does not start at all, a common reason is that one or two capacitors are damaged. All you need to do to repair it is to replace them, and you’re good to go. It’s quite easier than you think, and I’ll show you how. I was tasked with repairing a VGA monitor, namely an LG Flatron W1934S, that would not turn on anymore. All I could see what the blue power LED blinking regularly, about every two seconds. Since so far, I had a 100% success rate in failing to repair TVs, I was not confident, and I thought maybe the monitor is some special state making it not turn on, as it happened to me with another monitor a few years ago. But a web search revealed the problem was probably a power supply board issue with one of the capacitors damaged and, in theory, […]
