Elecrow CrowVi review

Elecrow CrowVi VF156T  – or just CrowVi for shorts – is an ultra-thin 15.6-inch portable touchscreen display with mini HDMI and USB-C input ports making it suitable for a wide range of devices from Windows 11 and Linux mini PCs or laptops, SBCs such as the Raspberry Pi 5, and smartphones featuring a USB-C port with DisplayPort Allt. mode. The display supports 10-point multitouch, offers a 1920×1080 “Full HD” resolution, and includes stereo speakers and a 3.5mm audio jack. Besides the USB-C input, it also comes with an additional USB-C PD port for power in case the host does not provide enough power or only HDMI input is used without the touchscreen function. There’s also a “smart case” acting as a foldable stand on the back so you don’t need to bring your own stand. Elecrow sent us a sample of the CrowVi 15.6-inch portable monitor for review and we […]

UniHiker review – A Linux-based STEM education platform with IoT and AI support, Micro:bit edge connector

UniHiker Review

DFRobot’s UniHiker is a STEM educational platform that was originally launched in China, but now UniHiker is now available worldwide through the DFRobot shop. The company has sent us a UniHiker sample for review, so let’s unpack the kit and learn how to use the UniHiker platform. The main component of the kit is the Linux-powered UniHiker board which features a 2.8-inch resistive touchscreen display and a BBC Micro:bit edge connector, so we can use expansion boards for the Micro:bit board. Let’s start unboxing it together. UniHiker unboxing DFRobot sent us the UniHiker platform by DHL. The package is a familiar-looking DFRobot box in orange color and comes with a plastic box to safely store the UniHiker board and accessories after use. The plastic box contains another plastic box with the board, some 3-pin and 4-pin cables for Gravity ports, and a USB Type-C cable. The UniHiker is like a […]

LicheePi 4A RISC-V SBC gets 16GB/128GB version, metal enclosure, 10.1-inch display, and more accessories

LicheePi 4A metal enclosure

LicheePi 4A quad-core RISC-V SBC is now available with 16GB RAM and 128GB eMMC flash, and Sipeed has also introduced various accessories such as a metal enclosure, a 10.1-inch touchscreen display, a PoE module, and a camera module. The Lichee Pi 4A board was first unveiled in December 2022, before the beta version launched in May 2023 with 8GB RAM and 8GB flash. Since then Sipeed also started selling an 8GB/32GB model, and now a new version of the T-Head TH1520-powered single board computer is now available with 16GB LPDDR4X and 128GB eMMC flash for $179 plus shipping. LicheePi 4A SBC While pricing is quite different, the LicheePi 4A was launched as a RISC-V alternative to the Raspberry Pi 4 SBC, so here are the specifications of the two boards side-by-side. Sipeed currently provides a Debian image based on Linux 5.10 and built with Yocto, but Linux mainline support is […]

Using BTT Pad 7 touchscreen display with Raspberry Pi CM4

BTT Pad 7 Raspberry Pi OS

The BTT Pad 7, or BIGTREETECH Pad 7 in full, is a 7-inch touchscreen display that ships with the CB1 Allwinner H616 system-on-module compatible with Raspberry Pi CM4. The display is mostly designed for 3D printers with its SPI and CAN Bus interfaces, but it can also be used as a standard tablet PC. So today, I’ll switch the CB1 with a Raspberry Pi CM4 Lite module and report my experience doing the conversion and using it as a Raspberry Pi CM4 tablet PC running Raspberry Pi OS, and test it with a 3D printer with Klipper in another post later on. Installing a Raspberry Pi CM4 (Lite) module in the BTT Pad 7 We’ll need the Pad 7, a Raspberry Pi CM4, and a few tools. The first step is to remove the red heatsink by loosening four screws with a 2.0mm hex key, as well as the cover […]

Manga Screen 2 is Smartphone Touchscreen Display with USB and HDMI Ports for Makers (Crowdfunding)

Most touchscreen displays aimed to be connected to a development board work through a display interface such as MIPI DSI or LCD RGB (and USB or I2C for touch support), and come with somewhat low resolution such as 800×480 which can be suitable for HMI applications. They also often don’t work with all boards due to the different interfaces used, and there’s no way to easily connect such small display to your computer. Taking those limitations into account, and since most boards and computers come with HDMI and USB ports, Elias Bakken and his team have added HDMI and USB ports to two smartphone displays, and Manga Screen 2 was born. The two displays – made by Sharp – have the following hardware specifications: Big (5.9”) Small (4.8”) Resolution 1920×1080 1280×720 FPS (max) 60 57 Color mode 24-bit PPI 376.2 307.9 Brightness 400 cd/m2 500 cd/m2 Contrast ratio 1000:1 800:1 […]

PQ Labs iStick A200 Android mini PC Connects to G4 Series Multi-Touch Screens

PQ Labs iStick A200 is a Rockchip RK3066 Android 4.1.1 mini PC with 2 GB RAM, 4 GB Flash, an HDMI (female) output, a USB 2.0 Host port, and a miniUSB port for power. Pretty boring stuff if you ask me… And I would not be writing about it, if the company hadn’t interfaced their infrared touch frames to this mini PC to allow 10-point multi-touch on a large screen or projector output, making it a pretty good solution for conferences and interactive digital signage. Before going further, let’s have a look at the details of specifications for the iStick A200: SoC – ARM Cortex A9 Dual Core @ 1.6Ghz with HyperSpeed (Equivalent to 2.0Ghz Dual Core) and Quad Core Mali400 GPU (cnxsoft: It has to be Rockchip RK3066) System Memory – 2 GB DRAM chipset Storage – 4 GB NAND flash + microSD socket (Up to 32 GB) Video […]
