Nezha RISC-V Linux SBC launched for $99 and up

Last month, we wrote about Allwinner D1 SBC & processor that promised to offer a relatively low-cost RISC-V Linux solution. We were not given a name at the time, but there was a logo of Nezha, a fictional character from Chinese literature. The board is now known as the Nezha SBC and has been launched on Indiegogo for $99 and up as a board designed for IoT projects running Linux, but can also be purchased directly on Aliexpress for the same price. [Update: It can also be purchased on Taobao for 599 RMB] Nezha SBC specifications: SoC – Allwinner D1 single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with HiFi4 DSP, G2D 2D graphics accelerators Memory – 1GB DDR3 memory Storage – 256MB SPI NAND flash, MicroSD card slot Video Output – HDMI 1.4 port up to 4Kp30, MIPI DSI & touch panel interface up to 1080p60 Decoding – […]

Beelink GKmini Review – An Intel Celeron J4125 mini PC reviewed with Windows 10 Pro, Ubuntu 20.04

Beelink have recently released another small form factor (SFF) design similar to the traditional Intel ‘NUC’ called the GKmini which they have provided for review. Available as a fully configured Windows 10 Pro mini PC means it can be up and running straight out of the box. Hardware Overview The Beelink GKmini physically consists of a 115mm x 102mm x 43mm (4.53 x 4.02 x 1.69 inches) rectangular plastic case. It is an actively cooled mini PC and uses Intel’s 14 nm J4125 Gemini Lake Refresh processor which is a quad-core 4-thread 2.00 GHz processor boosting to 2.70 GHz with Intel’s UHD Graphics 600. The front panel has a power button, a headphone jack, two USB 3.0 ports, and a ‘CLR CMOS’ pinhole that leads to a button which when pressed clears the CMOS. The rear panel includes the power jack, dual HDMI ports, a gigabit Ethernet port, a further […]

OpenMV PureThermal STM32H7 board overlays thermal map on RGB image

We’ve been writing about OpenMV open-source camera boards programmable with MicroPython at least since 2015, with the latest model OpenMV Cam H7 based on STM32H7 Cortex-M7 microcontroller introduced in 2018. But the company has now gone a step further with OpenMV PureThermal board equipped with a more powerful STM32H7 dual-core Arm Cortex-M7/M4microcontroller, and supporting FLIR Lepton 2 to 3.5 thermal imagers, allowing the system to overlay the thermal map on top of the image like an augmented reality app would do. It can do so on the integrated LCD display or on an HDMI display. OpenMV PureThermal features & specifications: MCU – STMicro STM32H7 Arm Cortex-M7 @ 480 MHz) and Cortex-M4 @ 240 MHz microcontroller Memory – 64MB SDRAM Storage – 32 MB of QSPI flash for the firmware, a microSD card slot for saving pictures and machine vision assets Display 800×480 touch Screen LCD DVI out for driving an […]

HEGduino V2 supports fNIRS and Blood-Flow Monitoring (Crowdfunding)

AlasKit has launched a crowdfunding campaign on Crowd Supply for HEGduino V2. The device features noninvasive optical imaging through fNIRS (Functional near-infrared spectroscopy), apart from its brain blood flow monitoring functionality. We saw the previous version of the HEGduino in September 2019 which only supported blood flow monitoring. But the HEGduino V2 also monitors breathing, heart rate, and skin temperature. HEGduino V2 has a MAX86141 optical pulse oximeter cum heart-rate sensor for incorporating Heart Rate Variability (HRV) training. It also allows breath and skin temperature monitoring. The sensor has a specification of 2×4096 SPS sensing with a 19-bit resolution which is a bit higher than its previous version. As HEGduino V1 had an 860 SPS sensing with a 16-bit resolution. However, the practical application observes even lesser values for HEGduino V1. Setup of HEGduino V2 The device also comes with an ESP32 breakout board with rechargeable battery support. The board […]

S805X2 AV1 Android TV dongles and TV boxes are starting to show up

Amlogic S805X2 AV1 capable processor was first teased as an update to S805X and S805Y Full HD TV box processors in 2019 with very little details. But companies have started to list some S805X2 based Android dongles and TV boxes. That means we also have additional details for the processor, and we’ll look into SDMC DV9035 TV box and SEI Robotics SEI103 dongle, neither of which should be sold to end-users, but instead OEM’s or content providers. SDMC DV9035 S805X2 TV box Specifications: SoC – Amlogic S805X2 quad-core Arm Cortex-A35 processor with Mali-G31 MP2 GPU System Memory – 1GB DDR4 Storage – 8GB eMMC flash Video Output – HDMI up to 1080p60 with HDR support Video Codecs – AV1, VP9, H.265, H.264 High-dynamic Range – HDR 10, HLG, HDR10+Optional Connectivity 10/100M Ethernet Dual-band 2.4GHz/5GHz 802.11a/b/g/n/ac WiFI 5 with optional 2×2 MIMO, Bluetooth 4.2 or higher USB – 2x USB 2.0 ports DRM – […]

US516P6 RISC microcontroller powers offline voice assistant modules

I recently wrote about a Linux microwave oven with a built-in voice assistant, and somebody mentioned a quad-core SoC was overkill, and instead US516P6 microcontroller designed for offline voice commands would be a better fit. It’s all good, but finding information about Unisound US516P6 proved to be quite a challenge with not much public information, and most in Chinese. But then I noticed Wireless Tag WT516P6Core offline voice module, and since I have contact with the company I managed to get a few more details, notable with regards to the development tools. US516P6 module specifications: MCU – Unisound US516P6 RISC microcontroller (likely Andes NDS32 based) @ 240 MHz with FPU, DSP instruction, FFT accelerator, 242KB SRAM, 2MB flash Audio – Built-in power amplifier I/Os – 12 castellated holes with UART, GPIO, microphone input, speaker output, VCC, and GND Power Supply – Built-in 5V to 3.3V, 3.3V to 1.2V LDO to […]
