Review of Nextion 4.3-inch Edge Series HMI touch display

Review 4.3-inch NEXTION HMI Edge 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 […]

AAEON NV8600-Nano AI Developer Kit Review – Part 2: Benchmarks, features testing, AI demos with Nx Meta

NV8600-Nano AI Developer Kit review with Nx Meta AI platform

In the first part of the review, I had a look at the hardware of the NV8600-Nano AI developer Kit featuring an NVIDIA Jetson Orin Nano 8GB module, booted it to Ubuntu 22.04, checked some system information, and made sure both the USB camera and Raspberry Pi Camera Module 2 (MIPI CSI) module worked fine.

I’ve now spent much more time with the Edge AI devkit, and report my experience in the second part of the review with some benchmarks, key features testing, and AI vision demos using Network Optix Nx Meta IP video management platform with the provided USB camera and an ONVIF-capable network camera.

Pironman 5 Mini is a cheaper Tower PC case for the Raspberry Pi 5

If you found the Pironman 5 and Pironman 5 Max Tower PC cases for the Raspberry Pi 5 pretty cool, but had a hard time justifying paying much more for the enclosure than for the board itself, SunFounder has an update for you. The company has now introduced the Pironman 5 Mini Tower PC enclosure with a similar, yet smaller design, fewer features, and easier assembly, bringing the price down to $45.99. That means the OLED information display, most RGB LEDs, the oversized tower cooler, the micro HDMI to HDMI adapter board, and more are all gone. Pironman 5 Mini features: Compatible SBC – Raspberry Pi 5 only. The Raspberry Pi 4 won’t work, and I can’t think of another SBC with two micro HDMI ports and the exact same layout as the Pi 5. Storage MicroSD card slot Optional NVMe SSD via M.2 M-Key (2230/2242/2260/2280) PCIe 2.0/3.0 socket Video […]
