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 – […]

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 […]

Arduino Nano RP2040 Connect WiFi & Bluetooth board launched for $25.50

The Arduino Nano RP2040 Connect board was announced the day of Raspberry Pi Pico launch as one of the third-party boards featuring Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller. At the time all we had was renders of the board, later on, the company showcased some mass product photos, and then released Arduino Core mbed 2.0 for the board last month. But it’s only today that it has become possible to purchase Arduino Nano RP2040 Connect board for $25.50 on Arduino store with headers. Nano RP2040 Connect specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller @ 133 MHz with 264 kB of embedded SRAM Storage – 16MB Flash IC (AT25SF128A) Connectivity – WiFi 4 & Bluetooth LE via Nina W102 uBlox module (Yes, that’s an ESP32 module.) USB – Micro USB port I/Os via 2x 15-pin headers (through and castellated holes) 20x digital I/O pins, 20x PWM pins, 20x […]

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 […]

Framework Laptop upgradable, repairable & modular laptop pre-orders opened for $799 and up

Most laptops are not made to be serviced by the end-users or expanded. In the part of the world where I live, I still have a “warranty void” sticker if I open my laptop to add an M.2 SSD. There are very few laptops with full documentation and whose companies encourage users to update and modify the hardware. Olimex TERES-I and MNT Reform 2 open-source hardware laptops do offer modularity, customization, and repairability, but they are based on low-power Arm processors and cater to a rather niche market. However, a new company called Framework is preparing to launch a modular laptop that is easily upgradeable and repairable with a more powerful set of features. The Framework laptop is offered with a choice of 11th generation Intel Tiger Lake Core processor, up to 64GB RAM, up to 4TB SSD storage, a 13.5-inch display, a Full HD webcam, a 55Wh battery, and […]
