How to Use Nextion Serial Touchscreen Displays – Part 1: Standalone Mode

Itead Studio launched an Indiegogo campaign earlier this year for their Nextion TFT displays that can be connected to external board such as Arduino or Raspberry Pi via the serial interface, or even a standard computer provided you have a USB to TTL debug board. The campaign was successful with over 1,700 backers, and the company recently sent me two samples for review: a 2.4″ display and a 5″ display. In this post, I’ll look at the boards, and make a small standalone demo with Nextion Editor in Windows. Nextion NX3224T024 2.4″ Display The first item is a 2.4″ TFT display called NX3224T024_011N (non-touch) or NX3224T024_011R (Resistive touch) with 65536 color, 320×240 pixel resolution, LED backlight and up to 200nit brightness. It ships with a cable for the serial connection (5V, Tx, Rx, and GND). The back of the display features the serial connector, a micro SD used to load the […]

Getting Started with NodeMCU Board Powered by ESP8266 WiSoC

Since ESP8266 is now so popular, I’ve recently bought a NodeMCU board to try it. I selected this board because the latest version of the board is breadboard-friendly, integrates a USB to serial chip, and it can be powered by a simple USB to micro USB cable. I also noticed a ESP8266 tutorial with NodeMCU firmware by SwitchDoc Labs the other day (using ESP-12 and Adafruit Huzzah), which I applied to my NodeMCU board, but since I encountered a few issues, I decided to report my findings, and write my own little getting started guide to switch on/off LED and GPIOs using a web interface. NodeMCU v0.9 and NodeMCU v1.0 If you are going to purchase a NodeMCU board it’s important to know there are two official versions: NodeMCU v0.9 with ESP-12 module NodeMCU v1.0 with ESP-12E module The main complain about NodeMCU v0.9 is that while it fits on […]

Top 10 Antutu Scores of 2015 for Smartphones So Far

I’m mainly focusing on Android mini PCs, and not so much on mobile devices. But this year, silicon vendors launched 64-bit ARM processor for TV boxes based on the low power Cortex A53 cores, lowering costs instead of improving performance of their 32-bit ARM processors, as media player don’t usually need very fast processor simply because video decoding is normally handled by the video engine. Two exceptions being Amazon Fire TV 2015 which gets over 51,000 points mostly thanks to MediaTek MT8173‘s two Cortex A72 cores, and Nvidia Shield Android TV box getting over 68,000 points, but sadly these two devices are not (easily) available worldwide yet. But on the mobile space, the race to faster and faster performance is still on, and according to a recent post on Antutu website (in Chinese), the fastest smartphones now reach over 75,000 points in the popular benchmark. I had to look up the […]

Kingnovel R8 Android TV Box Review (VLC Edition)

Kingnovel R8 is one of the many Rockchip RK3368 based TV boxes on the market, and since I’ve already provided the specs, as well as pictures of the device and board, I’ll carry on with the review today. While I’m usually testing video playback in Kodi, I’ve only spent a short time with Kodi 15.2 on this box, and instead switched to VLC (aka VideoLAN), an another open source media player, and my favorite program to watch videos in my Ubuntu computer. Of course, I’ve also tested most hardware features and performance of the device. First Boot, and First Impressions Since I like to test worst case scenarios, I also make sure I use all the ports of the devices, and connected a USB hard drive, USB RF dongles, USB webcam, and relevant cables to the device before powering it up. Once you connect the power, I recommend you have […]

How to Install Antutu Video Tester 3.0 and Video Sample Files Manually

I’ve been running Antutu Video Tester for my TV box reviews for over a year. I usually simply install Antutu Video Tester 2.2 from Google Play, then there’s a prompt offering to upgrade to Antutu Video Tester 3.0 (as for some reasons it’s not in Google Play) and once this is done, the app will download the video samples from some server before starting the test. However, recently it’s become a pain as I’ve had numerous problems installing the latest version of the app, and then downloading the video samples, as it may take 2, 3 or 4 hours to download all the necessary files from Antutu server, and once or twice I just gave up. As the problem occurred yet again today, I decided to install the benchmark app manually. China Gadgets Reviews provides several download links with AVT 3.0 apk and the video samples, and I select my […]

How to Use an ESP8266 Board as a WiFi to Serial Debug Board

Telnet and SSH are great to access a Linux device, machine and computer remotely when they are already running, but when you are working on the bootloader and/or kernel themselves, you’ll have to use a serial port to access the terminal / serial console. Boards used to get an RS232 port which you connected to your computer with a NULL modem cable, but these days, most boards and devices expose TTL signals and require a USB to TTL debug board to access the console via a USB cable. If you only have one device close to you computer that’s fine, but if your testbed is a little further. or you need to access the serial console on multiple boards you could consider using ESP8266 module to export the terminal over WiFi. This is exactly what Zoobab did above with a GL.inet router running OpenWRT and NodeMCU board with ESP-12(E) module […]

EzeeCube Linux Media Hub Unboxing and Teardown

EzeeCube is a Linux based Kodi Media Hub powered by Freescale i.MX6Quad processor with one internal 1TB hard drive and up to 8TB extra storage via four stackable 2TB hard drive module, as well as an option for a Blu-Ray player module. Beside playing video, it’s also designed to store your pictures and videos like a cloud service such as dropbox, but without privacy concerns since data is only stored in your own EzeeCube. The company launched an Indiegogo campaign in Q2 2014 which ended up being pretty successful having raised over $160,000, and as they are now shipping rewards to backers, I’ve also been sent a unit. Today, I’ll check out the hardware, and will review the unit probably sometimes next month. EzeeCube Unboxing The device came in a cardboard package with some EzeeCube branding, and some features like Freescale quad core processor, a 2TB hard drive (which finally […]

Review of WeTek Core Android Lollipop Media Player

EThe first devices based on Amlogic S812 processors started shipping by the end of 2014, but in the third quarter of 2015, there’s been a few new device released as some companies ported Android 5.x Lollipop to the platform. I reviewed two of these. Mygica ATV1900AC had potential but the number of bugs was disappointing, while Tronfy MXIV Telos was almost a disaster. Today, I’m going to report my test results with WeTek Core Android 5.1 TV box, also powered by Amlogic S812, more exactly S812-H, which includes DTS and Dolby licenses. I’ve already listed the specs, and torn down WeTek Core in two previous posts, so I’ll focus on the firmware in this review. Initial Setup and OTA Firmware Update First of all, I’d like to mention that I got an early WeTek Core sample, and while the hardware is frozen, the firmware is still being developed before the […]
