ALFA Network HaLow-U is an 802.11ah WiFi HaLow USB adapter based on the Newracom NRC7292 chipset and NXP i.MX 6 processor that works both in access point (AP) and client (STA) modes. It delivers long-range WiFi up to one kilometer in the 900 MHz frequency ISM bands and is mostly useful for IP cameras and high-end sensors. The ecosystem around WiFi HaLow (802.11ah) is expanding slowly, but surely, and we previously covered a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras, and also ALFA Network’s AHPI7292S Raspberry Pi HAT that found its way into RAKWireless WisGate Connect gateway. The new HaLow-U USB adapter adds another way to bring WiFi HaLow connectivity to more devices. HaLow-U specifications: SoC – NXP i.MX6 Arm Cortex-A9 processor System Memory – 256MB DDR3 Storage – 32MB NOR flash Connectivity 802.11ah HaLow Newracom NRC7292 chipset […]
The A2C caberQU and C2C caberQU boards enable the quick and easy testing of respectively USB-A to USB-C and USB-C to USB-C cables without external hardware. Powered by a CR2032 coin cell battery, the boards apply a voltage to all pins of a cable and measure which ones are connected to the other end. The results can be visualized immediately through various LEDS on the board. The C2C caberQU board comes with a dedicated LED for each of the 24 USB pins and the shield, and it’s possible to test the USB Type-C to USB Type-C cable in several different modes: USB 2.0/1.1 USB Power Delivery USB 3.0/3.1/3.2 Alternate Mode Debug Accessory Mode Audio Adapter Accessory Mode The A2C caberQU board has fewer pins and LEDS for testing USB-A to USB-C cables specifically, but it works the same way. Peter Traunmüller (aka petl) has shot a video showing one of […]
SB Components’ Lo-Fi is an ESP32-S3 board equipped with a LoRa module for low-power long-range connectivity, and the company has also introduced two LoRa USB dongles with either Type-A or Type-C connectors. Lo-Fi specifications: Wireless module ESP32-S3-WROOM-1: SoC – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, WiFi 4 & Bluetooth 5 LE/Mesh Memory – 8MB OSPI PSRAM Storage – 8MB QSPI flash PCB antenna Dimensions – 25.5 x 18.0 x 3.1 mm Unnamed LoRa module Tx power of up to 22dBm (160mW) adjustable by software Rx sensitivity of up to -138 dBm ISM bands – 433MHz, 868MHz, and 915MHz Range – Up to 5km range Data rates – 300 bps to 62.5 kbps RoHS compliance External LoRa antenna Display – 1.14-inch TFT display with 240×135 resolution USB – 1x USB Type-C port for programming and power Expansion – 2x 20-pin GPIO headers […]
Elecrow CrowView is a lightweight 14-inch portable monitor designed to be attached to your laptop adding a secondary monitor to it through a clamping structure that works with laptops having a 13-inch to 16.5-inch display. We’ve seen this type of laptop monitor extension for years, and you’ll find various models on Amazon. But the Elecrow is now offering the CrowView at a significantly lower price than competitors especially if you pledge $114.90 for the super early bird reward on Kickstarter. The regular price ($179) can still be interesting as in this price range you’d usually get an 11-inch or 12-inch display. CrowView specifications: 14-inch IPS display with 1920×1080 resolution, 60 Hz refresh rate, 400 nit brightness Compatible with 13-inch to 16.5-inch laptops with 4 to 8mm thick displays thanks to a telescopic snap 230° hinge enabling face-to-face mode. Ports Mini HDMI port for video input 2x full-featured USB Type-C port […]
The CZUR ET24 Pro is a professional book scanner that works with Windows, macOS, and Linux, so I decided to review it in Ubuntu 22.04 since we are fans of hardware that can interface with Linux at CNX Software.
If you haven’t already, I strongly recommended reading the unboxing part of the CZUR ET24 Pro review, as we go through the specifications, show the various interfaces of the scanner, showcase the various accessories, and also try it out with the HDMI interface in presentation/preview mode. It will help you better understand the second part of the review, where we’ll connect the CZUR ET24 Pro scanner to a Ubuntu 22.04 laptop using the provided USB cable.
CZUR ET24 Pro is a professional book scanner with 320DPI optional resolution (delivering up to 24MP images) that works with Windows, macOS, and Linux via a USB port, or even in standalone mode through an HDMI port that could be used for business presentations. When CZUR contacted me about reviewing a scanner, I was not sure it would be interesting, but then I was intrigued because it looks like a bedside light and I had never used this type of scanner. So I decided to give a go, and here I am with a review sample. It looks like it should be especially useful for people scanning a lot of documents or books as it’s designed for speed and should significantly improve productivity over a traditional scanner with a cover, while hopefully keeping the quality. But we’ll check that in the full review. CZUR ET24 Pro specifications Optical resolution – […]
Diabolic Drive may look like a 64GB USB flash drive and show as such when you insert it into your computer, but it’s actually a wireless keystroke injection tool with a Microchip ATmega32U4 8-bit AVR microcontroller and an Espressif Systems ESP8266 WiFi SoC. Egypt-based UNIT 72784 says their cyber security tool enables Red Teaming – the practice of rigorously identifying an attack path to breach a device’s security – as it behaves like a flash drive while being able to deploy keyboard strokes wirelessly through the ESP8266 WiFi MCU. Diabolic Drive specifications: MCUs Microchip ATmega32U4 microcontroller @ 16 MHz (5V) acting as a Serial Bridge Espressif Systems ESP8266EX microcontroller @ 160 MHZ (3.3V) with WiFi 4 support ATmega32U4 and ESP8266 are connected via Serial and I2C protocols thanks to an LDO regulator. Storage 64 GB flash storage up to 20MB/s read, 10MB/s write 4MB W25Q32 SPI flash memory o Antenna […]
