4Duino-24 is an Arduino compatible 2.4″ Color IoT Display Module with Atmel MCU and ESP8266 Module

I played with ITEAD Studio NEXTION serial color displays for Arduino boards and the likes a few months ago, and while the hardware seems good and the company offer a large choice of 2.4″ to 7″ models at a very affordable price, I didn’t find the Windows software to create the user interface to be very user-friendly. 4D Systems, an Australian company specializing in “graphics solutions”, will soon launch a similar 2.4″ display, but integrated into an Arduino compatible board also featuring an ESP8266 module for WiFi connectivity. 4Duino-24 “LCD  IoT Display Module” specifications: MCU – Atmel ATmega32U4 micro-controller with 32KB flash, 2.5KB SRAM, 1KB EEPROM Storage – micro SD card slot (FAT16 support) for data and logging WiFi Module – ESP8266 based with 802.11 b/g/n connectivity, 1MB flash, support for Wi-Fi Direct (P2P), soft-AP Display – 2.4” LCD-TFT resistive touch display module with 240×320 resolution, 65K colors, and powered […]

Cleo35 Touchscreen Display for Arduino UNO Comes with Tutorials and Example Projects (Crowdfunding)

There are already various options to add a (touscheen) display to Arduino board with software support including TFTLibrary for Arduino,  and recently I tried Nextion serial touchscreen displays that are supported by a WYSIWYG editor, but the latter is only supported in Windows and not exactly user-friendly, and I found the few provided tutorials would only work with a specific resolution incompatible with the displays I had been sent. So I gave up on the idea of interfacing the display with Arduino or ESP8266 as it would be too time-consuming. FTDI CleO project might be faster and easier to get started, as their CleO35 touchscreen display for Arduino UNO will come with a 20 chapter tutorial covering over 80 topics, and 20 projects to get started. Some of the key features and specs of Cleo35 display include: MCU – FTDI FT903 32-bit FT32 core @ 100MHz with 256kB on-chip Flash […]

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 […]

Low Cost 15.6″ Portable DVD Player Could Be Used as a Cheap Battery Powered HDMI Display

I’ve already written about portable displays with products such as Gechic On-Lap Monitors which sells for $200 and AOC USB Portable monitors are also popular, and somewhat cheaper than I expected at $120 and $199 for a 15.6″ display at respectively 1366×768 and 1920×1080 resolution, although if you live outside the US, shipping and import fees deposit bring the price much higher. A search for “portable display” on Aliexpress only showed some smaller 3.5 to 7″ displays, but I’ve been tipped about a 15.6″ portable DVD player selling for $114.53 on Chinavasion that could be used as an external display too thanks to its HDMI input. Specifications of this portable DVD player: SoC – Mediatek Solution Display – 15.6″ TFT LED Screen with 270 degree swivel; 1366×768 resolution; 16:9 aspect ratio Disc support – DVD, CD, EVD, VCD, CD-RW, DVD-R. Hitachi lens Video Output – AV Video Input – HDMI, […]

Nextion 2.4″ and 4.3″ UART TFT Displays Come with a Drag and Drop UI Editor (Crowdfunding)

You may want or need to add a small TFT display to control your devices, and it may not always be easy to interface with the hardware, and desiging the user interface may be time consuming. ITEAD Studio latest project, Nextion TFT HMI touchscreen displays, aims to simplify connection with a simple UART interface, and make UI design easier with their Nextion Editor that allows developers to create a user interface without coding.

Connect a 9.7″ Retina Display (iPAD 3/4) to Your Computer via a DisplayPort Adapter

One way to connect an extra Retina (2048×1536) display to your computer is to purchase Adafruit Qualia 9.7″ DisplayPort Monitor for $224.95. But in case your budget is limited, you could combine an old iPAD 3/4 display with AbuseMark 2048×1536 LCD to DisplayPort Adapter for 3,500 JPY ($29 US). If you don’t have an old iPAD, or would rather not dismantle your “old”-but-still-useful iPAD, you could purchase LG LP097QX1-SPC1/2, LG LP097QX1-SPA1/2/V, or Samsung LTL097QL01-W01 LCD panels instead for about $80 on Amazon US (LP097QX1 / LTL097QL01). If you live in Japan, AbuseMark also ships a complete kit for 12,000 JPY.   Key features listed for the board: Video Input – DisplayPort Display Connector – 51-pin 0.3mm pitch FPC connector STM32F103CB 32-bit Cortex M3 MCU with native USB for firmware update and power/brightness/etc control Dual TI TPS61187 WLED drivers Power – USB or 5V-powered (separate connector) / 1.35A total current draw.
