SignalSDR Pro is a high-performance software-defined radio (SDR) in Raspberry Pi form factor (Crowdfunding)

Raspberry Pi SDR board with AMD Zync 7020 SoC FPGA

The SignalSDR Pro is a Raspberry Pi-sized SDR that brings a credit-card-sized twist to software-defined radios (SDRs). It is a compact, streamlined device suitable for tasks ranging “from signal processing and spectrum analysis to communication systems and beyond.” The SignalSDR Pro builds on the Analog Devices AD9361 radio transceiver and the AMD Zync 7020 SoC into a credit-card format reminiscent of Raspberry Pi single-board computers. The Raspberry Pi-sized SDR also features a 40-pin GPIO header for expansion with other hardware components and added functionality. The device offers a 70MHz – 6GHz tuning range, 12-bit sample rate, 61.44MHz RF bandwidth, and two full-duplex TX/RX channels via four I-PEX antenna connectors. It is also capable of emulating other SDR hardware such as the ADALM-PLUTO and USRP B210, making it easier to integrate into pre-existing workflows. The SignalSDR Pro is a mid-range alternative to entry-level SDR options such as the AntSDR E200, KrakenSDR, […]

Sanwa Supply unveils a mouse with receiver acting as a USB/HDMI dock, and a 360-degree USB-C cable

Sanwa Supply wireless mouse USB dock HDMI

Japanese company Sanwa Supply has introduced two unusual devices to the market. First, a wireless mouse with an RF receiver that also acts as a USB dock with HDMI output, followed by a 360-degree USB-C cable to facilitate cable management. Sanwa Supply RF mouse with USB/HDMI dock Sanwa Supply 400-MAWBT209BK (black and silver) and 400-MAWBT209BK2 (black and blue) wireless mice come with a rather large USB Type-C 2.4GHz RF and Bluetooth receiver that not only allows the user to connect the mouse to a computer but also acts as a USB dock with an HDMI output port supporting up to 4Ko60 resolutions for monitors or projectors. The dock also exposes a 5 Gbps USB 3.2 Gen 3 USB Type-C port with PD support up to 100W (90W available to peripherals) which allows the users to connect peripherals such as USB SSD enclosures, memory sticks, and keyboards. Tom’s Hardware reports the […]

Hornet Nest Alarm Panel – An Home Assistant-compatible, ESP32 home security automation platform with PoE and 42-zone support (Crowdfunding)

Hornet Nest home security panel in operation

The Hornet Nest Alarm Panel is a customizable, ESP32-based alarm control system designed and produced by US-based Technology Automation Consulting for home security automation. The device is powered by the wESP32 Ethernet board with PoE support and is compatible with Home Assistant through the ESPHome firmware. It features up to forty-two optoisolated zones, six MOSFET-controlled outputs, and six additional trigger outputs for 3.3V devices. It integrates a piezo buzzer and supports add-ons like a Wiegand keypad and water leak sensors. The Hornet Nest Alarm ESP32-based home security platform “aims to bridge the gap between traditional wired security systems and the flexibility of modern smart home automation.” Christopher Greenless of Technology Automation Consulting says the project was born from his need for a robust and smart security system to integrate with his Home Assistant setup. Proprietary solutions were inadequate and limited while DIY options were inefficient and often unreliable. He created […]

Nordic Thingy:91 X multi-sensor cellular IoT platform combines nRF9151 LTE IoT SiP, nRF5340 BLE SoC, and nRF7002 WiFi 6 IC

Nordic Semiconductor introduced the Nordic Thingy:91 in mid-2019, a cellular IoT prototyping platform built around the Nordic nRF9160 system-in-package (SiP). It supports LTE-M, NB-IoT, and GPS, and includes features like an Arm Cortex-M33 core, Arm TrustZone security, and flash memory. The platform is ideal for creating IoT Proof-of-Concepts, demos, and prototypes, making it easy to test and deploy IoT applications. The upgraded Nordic Thingy:91 X features the new Nordic nRF9151 SiP, offering support for LTE-M, NB-IoT, GNSS, and DECT NR+ for global connectivity, integrates the nRF5340 SoC for USB and Bluetooth LE, and the nRF7002 IC for Wi-Fi locations. The platform includes sensors for environmental and motion sensing, one expansion connector for Qwiic/STEMMA QT and Grove modules, and antennas for LTE, GNSS, and Wi-Fi. Additionally, the kit also features a Nano/4FF SIM slot, two SIM cards, and a 1,350 mAh Li-Po battery managed by nPM6001 and nPM1300 PMICs, to support field […]

Linux 6.11 Release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.11 is out with Linus Torvalds’ announcement on the Linux kernel mailing list (LKML): I’m once again on the road and not in my normal timezone, but it’s Sunday afternoon here in Vienna, and 6.11 is out. The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small. Nothing in particular stands out – the biggest patch in here is for Hyper-V Confidential Computing documentation. Anyway, with this, the merge window will obviously open tomorrow, and I already have 40+ pull requests pending. That said, exactly _because_ I’m on the road, it will probably be a fairly slow start to the merge window, since not only am I on my laptop, there’s OSS Europe starting tomorrow and then the […]

LibreELEC 12 released with Kodi 21, 64-bit Arm support for Raspberry Pi 4/5, and platforms

As one should have expected after the Kodi 21 “Omega” release last month, the LibreELEC 12 lightweight Linux media center distribution is now out with many devices updated to 64-bit, including the Rasberry Pi 4 and 5 SBCs. LibreELEC 11 was released last year based on Kodi 20 “Nexus” and bringing back support for Amlogic devices. LibreELEC 12 builds on that and benefits from the new features added to Kodi 21 such as FFmpeg 6 and works on Arm platforms based on Allwinner, Amlogic, Broadcom (Raspberry Pi), and Rockchip processors, as well as generic x86 computers. It’s an easy option to create a dedicated HTPC based on a range of hardware with all the features brought by Kodi 21 media center. Since so many platforms are supported there are always some limitations for each and known problems: Raspberry Pi – 50/60fps H.264 HW decoding may need force_turbo=1 or core_freq_min=500 in […]

Rockchip roadmap reveals RK3576 and RK3506 IoT processors, Linux 6.1 SDK

The Rockchip RK3588 processor may remain the most powerful processor from the company for a while as an updated Rockchip IoT processor roadmap reveals the new RK3576 octa-core SoC and RK3506 tri-core Cortex-A7 chip, as well as a Linux 6.1 SDK to be released in Q4 2023. With the limited information we have, the Rockchip RK3576 looks to be a cost-down version of the RK3588 processor with eight cores, a 6 TOPS NPU, a 4K video codec, as well as PCIe and USB-C interfaces. Strangely the Rockchip RK3582 that should serve a similar purpose is not showing up in the roadmap. [Update: The RK3576 is indeed a lower-cost SoC but features four Cortex-A72 and four Cortex-A53 cores instead as per the comparison table reproduced below: That also means we now have the RK3576 specifications (some obtained from another document too): CPU Octa-core Arm processor with 4x Cortex-A72 cores at 2.2 […]
