CrowVision review – An 11.6-inch 1366×768 touchscreen display that works with multiple SBCs

Raspberry Pi 4 CrowVision Touchscreen Display Tester

CrowVision is an 11.6-inch IPS capacitive touchscreen display with 1366×768 resolution that is designed to work not only with the Raspberry Pi but most single board computers with mounting holes within a 100 x 80 mm rectangle. Elecrow sent me a sample so I’ll try it out with a Raspberry Pi, a Windows 11 mini PC, and a Ubuntu 22.04 laptop to make sure it works well with those operating systems. CrowVision unboxing The packages include the display module itself, a 12V/2A power adapter, USB Type-C and micro USB cables, an HDMI to mini HDMI cable, a micro HDMI to mini HDMI cable, two “ribbons” for cable management, a screwdriver, an OSD control board with five keys, and a user manual. The display does not come with an enclosure, so it’s better suited for DIY projects where users design their own enclosure or mounting solution. The control board is based […]

Ultrawide 8.8-inch HDMI and USB information display is offered with optional touchscreen support

8.8-inch information display HDMI USB touchscreen

Last year, I wrote about the Turing Smart Screen low-cost 3.5-inch display based on a WCH CH552T 8-bit E8051 core microcontroller that connects to a PC or other device through a USB Type-C cable in order to display system or other information using AIDA64 software or an open-source Python software. I’ve just come across another display that appears to serve the same purpose, except the “GeekTeches V35” is an ultrawide 8.8-inch display with 1920×480 resolution, micro USB and micro HDMI interfaces, and optional support for a touchscreen. GeekTeches V35 specifications: Display 8.8-inch IPS display with 480×1920 resolution (21:9 aspect ratio) with optional touch screen Pixel size – 0.114 x 0.114 mm Display area – 54.72 x 218.88 mm Wide display angle Brightness – 550cd/m2, adjustable Driver: IC/LCM Driver IC Display interface – “MIPI BIT interface”. Not sure what this is… a typo for MIPI DSI? Backlight current – 160ma Backlight […]
