Black Friday and Cyber Monday 2025 – International deals, coupons, and events
Like every year since 2014, I’ll list a few international deals for Black Friday and Cyber Monday 2025, as many CNX Software readers cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events, which will take place from November 20 to December 1. I’ve gathered various deals, discount coupon codes, and events from relevant manufacturers of single board computers, MCU development boards, mini PCs, Smart Home devices, and DIY products, as well as popular online stores, including AliExpress, Banggood, and others. AliExpress Black Friday and Cyber Monday 2025 event AliExpress sales event for Black Friday and Cyber Monday 2025 has just started and will last until December 3, 2025 (although I can see until November 29 and December 4 in some places). You can use some of the coupons on the screenshot above, or some alternative coupon codes for the US and some other countries (excluding DE, RU, […]
Bluetooth 6.2 gets more responsive, improves security, USB communication, and testing capabilities
Bluetooth 6.2 specification has just been released with a range of new features to enhance responsiveness with shorter connection intervals, strengthen security against amplitude-based RF attacks, and improve communication with a new “Bulk Serialization Mode” that’s especially useful for USB Bluetooth LE audio applications. The new Bluetooth Core 6.2 specification also introduces various BLE Test Mode enhancements. If you feel like Bluetooth specifications are released more often than in the past, that’s normal because the Bluetooth SIG switched to a bi-annual release schedule. For instance, the Bluetooth 6.1 specification was just published last May, or about 6 months ago… Bluetooth 6.2 highlights: Bluetooth Shorter Connection Intervals (SCI) reduce the minimum Bluetooth LE connection interval from 7.5 ms to just 375 µs for faster responsiveness. The change will especially impact high-performance HID devices, real-time human-machine interfaces (HMIs), and latency-sensitive sensors. AR/VR and gaming applications will particularly benefit from the lower latency. […]
Review of Nextion 4.3-inch Edge Series HMI touch display
Today, we’ll review the Nextion 4.3-inch Edge Series HMI touch display. The company has recently launched the new Edge Series HMI touch displays for IoT applications that require better user interaction. It also supports video and audio playback, and everything can be configured relatively easily by the user using Nextion Editor software, version 1.68.1 or higher. The Edge Series HMI touch displays offer a wide range of screen sizes and formats to choose from, including a 2.1-inch round model (NX4848E021-011C) and a 2.8-inch round model (NX4848E028-011C), both with 480×480 resolution, as well as a 4.3-inch rectangular model (NX4880E043-011C) with 800×480 resolution. We received the NEXTION NX4880E043-011C Edge Series HMI touch display for review, along with accessories, namely an IO board and a speaker, so we can get hands-on and dive deep into the review. It’s versatile for all sorts of applications, from AIoT devices and vehicle control systems to medical […]
MIPI SoundWire I3S (SWI3S) targets high-bandwidth, low-latency audio applications
The MIPI Alliance has recently released the SoundWire I3S (MIPI SWI3S v1.0) specification for high-bandwidth, low-latency audio applications which unify control and data over a single, power-efficient interface. SWI3S builds upon the two-pin, multi-drop architecture of MIPI SoundWire released in 2014, and offers higher bandwidth, low power consumption, much better noise immunity, and support for scalable multi-device topologies to meet the increasing requirements of embedded audio systems. MIPI SWI3S v1.0 supports data rates up to 76 Mbps against 24 Mbps for the earlier SLIMbus and SoundWire audio interfaces, and improves noise immunity by operating in “forwarded clock” or “differential low voltage signaling”. It also implements a range of new features such as Hubs, multiple PHY support, control CRC, power-saving techniques, and more. MIPI SoundWire I3S key features: Transports audio data, control commands, interrupt signals, and synchronization information over a unified two-pin link Forwarded bit clock single-ended (FBCSE) and differential low-voltage […]
