Giveaway Week – e-con Systems e-CAM20_CURB camera

Today, we’re giving away the e-con Systems e-CAM20_CURB is a 2.3MP color camera with a global shutter that is designed to work with Raspberry Pi 4 SBC. The camera is based on ON Semiconductor AR0234CS CMOS sensor and supports uncompressed video at 1920 x 1200 (2.3MP) up to 60 fps, 1920 x 1080 (Full HD) up to 65 fps, and 1280 x 720 (HD) up to 120 fps. I just completed the e-CAM20_CURB camera review with Raspberry Pi 4 last weekend and found the video smoothness and quality to be much better than most cameras I’ve tried when there is motion, even in relatively dark scenes, since motion blur and artifacts are reduced. The company provides Yocto Linux and Raspbian/Raspberry Pi OS images with V4L2 drivers and Gstreamer tools, and the camera was fairly easy to use with the Yocto image thanks to the useful documentation provided with the kit.

MS2130 based “4K” HDMI to USB 3.0 video capture dongle sells for $19

Mini U3 MS2130 4K HDMI to USB 3.0 video capture dongle

4K HDMI to USB 3.0 dongles based on Macrosilicon MS2130 video and audio acquisition chip are starting to show up on Aliexpress for around $19 with free shipping. We first discovered the MS2130 chip in the YuzukiLOHCC PRO open-source hardware board that claims to have a bills-of-material cost of about $10. But you have to build it and source the components yourself, so it’s not for everyone. Now USB 3.0 adapters capable of recording or streaming up to 1080p60 uncompressed video from an HDMI input up to 4Kp30 are available to anyone with around $20. “Mini U3” HDMI to USB 3.0 video capture dongle specfications: Main chip – MacroSilicon/UltraSemi MS2130 USB 3.2 Gen 1 high-definition video and audio acquisition chip HDMI input up to 4Kp30, 24/30/36-bit depth color Video Output up to 1080p60 in YUV or JPEG output format Audio – L-PCM codec Input cable length – Up to 15 […]

RP2040 firmware converts Raspberry Pi Pico into a an I2C to USB bridge

Nicolai Electronics’ rp2040-ic2-interface open-source firmware for the Raspberry Pi Pico (or other Raspberry Pi RP2040 boards) converts the board into an I2C to USB bridge to connect any I2C sensor or module to a PC or other hardware without GPIOs. The firmware implements the USB protocol expected by the I2C-Tiny-USB kernel driver used by the original I2C-Tiny-USB project for Microchip ATMega 8-bit AVR microcontrollers. The RP2040 is however not a fork of the original project, but instead a complete re-implementation of the firmware. You’ll need to connect your I2C sensor, display, or another module to the SDA (GPIO 2) and SCL (GPIO 3) pins of the Raspberry Pi RP2040 microcontroller and flash the “pre-release” firmware to the board. You’ll find it together with the source code written in C language on GitHub. Note the project has a “proof of concept status” and more testing is needed to make sure that […]

Giveaway Week – NanoPi R5S router

It’s that time of year… CNX Software giveaway week! For the 9th edition, we’ll have seven items to give away, five that I will send myself, and two that will be sent directly from two companies that accepted to add their own products to the giveaway. We’ll start the giveaway with NanoPi R5S router based on Rockchip RK3568 SoC with 2 GB DDR4 RAM, 8GB eMMC flash plus an M.2 socket for NVMe SSD, two 2.5GbE Ethernet ports, one Gigabit Ethernet port, as well as HDMI 2.0 video output and two USB 3.0 ports. I reviewed the NanoPi R5S router with OpenWrt and Ubuntu 20.04 “FriendlyCore”, but I had to call this a “preview” since 2.5GbE was far from optimal, sometimes only a little faster than with a Gigabit Ethernet link. But I can see the company has released new images, including one based on the latest OpenWrt 22.03, […]

Beelink SEi12 Alder Lake mini PC review with Windows 11, Ubuntu 22.04

Beelink have launched their first Intel Alder Lake mini PC calling it the SEi12. Featuring a mobile 12th gen Core-i5-1235U processor it is also their first mini PC to incorporate a PCIe4 NVMe slot. Beelink kindly sent one for review and I’ve looked at the performance running both Windows 11 and Ubuntu 22.04. Beelink SEI12 hardware overview The Beelink SEi12 physically consists of a 126 x 113 x 42mm (4.96 x 4.45 x 1.65 inches) square metal case with a new and innovative waterproof fabric-covered top. As an actively cooled mini PC, it uses Intel’s Alder Lake Core i5-1235U processor which has a thread count of 12 with 2 ‘performance’ cores boosting to 4.40 GHz and 8 ‘efficient’ cores boosting to 3.30 GHz and includes Intel’s Iris Xe Graphics. The front panel has an illuminated power button, a 3.5mm headphone jack, a data-only Type-C USB 3.1 port, dual USB 3.1 […]

T-Head XuanTie C908 RISC-V core targets AIoT applications

We’ve seen two announcements of high-end RISC-V cores this week with the SiFive P670 and Andes AX65 processors each with a 4-way out-of-order pipeline, but Alibaba’s T-Head Semiconductor Xuantie C908 is a little different with a dual-issued, 9-stage in-order pipeline and support for the RISC-V Vector extension acceleration targeting mid-range AIoT applications. The C908 64-bit RISC-V core adopts the RV64GCB[V] instruction and complies with the RVA22 profile for better compatibility with Android and other “rich” operating systems. The company says its performance is between the C906 and C910 cores introduced in 2020 and 2019 respectively. XuanTie C908 highlights: RV32GCB[V] 32-bit and RV64GCB[V] 64-bit RISC-V architectures with Bit manipulation and (optional) Vector operations extensions Support for RV32 COMPAT mode which allows for 64-bit RISC-V CPUs to run 32-bit binary code, and was merged into Linux 5.19. XuanTie extensions, including Instruction, Memory Attributes Extension (XMAE). RVA22 profile compatibility Cluster of 1 to […]
