Cincoze DS-1402 review – Part 2: An Intel Core i9-12900E embedded computer tested with Windows 11 Pro

Cincoze DS-1402 Embedded Computer Review Windows 11

I’ve already checked out the hardware of the Cincoze DS-1402 modular embedded computer in the first part of the review with an unboxing and teardown of the Intel Core i9-12900E computer that ships with expansions such as an NVIDIA GTX 1630 graphics card held in place with a patented solution and two CMI expansion modules with four gigabit Ethernet ports each. I’ve now had more time to test the Cincoze DS-1402 with Windows 11 Pro, so I’ll report my experience with the system in the second part of the review checking out system information, testing features, running benchmarks, evaluating networking and storage performance, testing the thermal design, and taking measurements for fan noise and power consumption. I’ll also compare some of the second to the GEEKOM XT12 Pro mini PC powered by an Intel Core i9-12900H SoC since embedded SKUs – like the Core i9-12900E – are usually slightly slower […]

MyoWare 2.0 Muscle Sensor Wireless Kit targets electromyography (EMG) applications

MyoWare 2.0 Muscle Sensor with ESP32 Arduino board

The MyoWare 2.0 Muscle Sensor Wireless Kit is an Arduino-compatible electromyography (EMG) sensor kit capable of detecting and measuring the electrical signals generated by muscle fibers in the body. The MyoWare 2.0 kit is a collaborative product by SparkFun and Advancer Technologies. The MyoWare 2.0 ecosystem brings several improvements over the previous generation, including a compact design, solderless snap connectors, and an upgraded chipset for improved reliability and performance. It includes shields designed to seamlessly interface with the MyoWare 2.0 Muscle sensor, a wearable, Arduino-compatible EMG sensor. The Muscle Sensor’s wearable design makes it possible to directly attach biomedical sensor pads and add-on shields to the board. It operates on a single-supply voltage between +3.3V to +5V and supports three separate output modes. It analyzes filtered and rectified activity from muscle movement and outputs a signal from 0 to the power source voltage (VIN) that represents the intensity of flex. […]

Amlogic S905X5M vs S905X4 – Features and benchmarks comparison

Amlogic S905X5M is an update to the Amlogic S905X4 quad-core Cortex-A55 SoC with a higher 2.5 GHz CPU clock and a new generation Arm G310 CPU that delivers up to close to three times the performance of the Mali-G31 MP2 GPU for more advanced and smoother HDR user interfaces. The S905X5M and S905X4 share the same video decoding capabilities, notably AV1 and H265 up to 4Kp75, but the new S905X5M drops support for H.265 1080p60 video encoding, only keeping H.264 1080p30. One of the new features is the inclusion of an NPU designed specifically for Super Resolution enabling video upscaling with better image quality. You’ll find the differences between the Amlogic S905X5M and S905X5 processors in the comparison table below. The Amlogic S905X5M adds some HDMI 2.1 features that deserve an explanation: QMS (Quick Media Switching) – A source device can instantly switch its content’s resolution or frame rate without […]

SONOFF SNZB-05P review – A Zigbee water leak sensor tested with eWelink and Home Assistant

SONOFF SNZB-05P Zigbee Water Leak Sensor review

Today, we will review another new sensor from SONOFF, the SNZN-05P Zigbee water leak sensor. This is SONOFF’s first-ever water leak detection sensor. In the past, we have reviewed other Zigbee sensors that were upgraded from previous models. SONOFF enthusiasts will likely be pleased because a water leak detection sensor is something that should have been part of the SONOFF ecosystem for a long time. That is a bit late in the game, but it has a unique feature: an Extended Detection Cable that can detect water leaks. Let’s take a look! SONOFF SNZB-05P Water Leak Sensor Unboxing Inside the box, you’ll find the sensor, an Extended Detection Cable (2m), cable clips, and a small manual. The SNZB-05P is water-resistant with an IP67 rating (submersible up to 1 meter for 30 minutes). It uses a CR2477 battery, similar to other SONOFF Zigbee sensors, which should last several years. Both terminals […]

RAUC open-source OTA update solution for embedded Linux ported to Rock Pi 4 SBC

RAUC open-source OTA update solution enabling A/B updates for embedded Linux images has recently been ported to the Radxa Rock Pi 4 Model B SBC powered by a Rockchip OP1 SoC by the project’s maintainer, Leon Anavi working for Konsulto Group. If you run a Linux distribution like Ubuntu, Debian, or Fedora, packages and OS images are taken care of automatically or by running a few commands. However, software engineers who build custom embedded Linux images with the Yocto Project or Buildroot must handle this themselves. Luckily, there are already open-source OTA firmware update solutions such as Mender, Balena, Torizon, OSTree, Snap, or RAUC, and we’ll look at the latter today. RAUC (Robust Auto-Update Controller) was started by Pengutronix in 2015 and eventually adopted by the community. It’s a lightweight update client that runs on an Embedded Linux device and controls the A/B update procedure when a new firmware revision […]

Sipeed Tang Mega 138K Dock is a lower-cost GOWIN GW5AST FPGA + RISC-V development board

The Sipeed Tang Mega 138K Dock is a low-cost version of the Tang Mega 138K Pro development board launched last year with the GOWIN GW5AST FPGA + RISC-V SoC, two SPF+ cages, a PCIe 3.0 x4 interface, and DVI Rx and Tx ports. The new Tang Mega 138K Dock keeps a GW5AST FPGA SoC but with a 484-ball package that fits on a smaller system-on-module, and does without the SPF+ cages, replaces the PCIe 3.0 x4 interface with a PCIe 2.0 x4 interface, and only uses a single HDMI port for DVI Rx or Tx. Sipeed Tang Mega 138K system-on-module Let’s first have a look at the specifications of the SoM itself: SoC FPGA – GOWIN GW5AST-LV138FPG484A with 138,240 LUT4 1,080 Kb Shadow SRAM (SSRAM) 6,120 Kb Block SRAM (BSRAM) Number of BSRAM – 340 298x DSP slices 12x PLLs 16x global clocks 24x HCLK 8x transceivers at 270Mbps to […]
