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 […]

Using BTT Pad 7 touchscreen display with Raspberry Pi CM4

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 […]

BeepBerry handheld Linux computer drives 2.7-inch display with Raspberry Pi Zero W

Good news! The PocketCHIP handheld Linux computer is back! OK, not quite but that’s what the Raspberry Pi Zero-powered BeepBerry reminds me of with a Blackberry-like keyboard, a small 2.7-inch display, and a 2,000mAh LiPo battery for power. The BeepBerry is another open-source hardware design from SQFMI, who previously did the Watchy ESP32 E-Ink smartwatch, that runs Raspberry Pi OS Lite on the Raspberry Pi Zero/Zero W, and also includes a Raspberry Pi RP2040 to handle the keyboard and peripherals. BeepBerry specifications: SBC – Raspberry Pi Zero board with a Broadcom BCM2835 ARM11 processor @ 700 MHz, VideoCore IV GPU, or Raspberry Pi Zero W with WiFi and Bluetooth Storage – MicroSD card slot Display – Ultra-low power high contrast 2.7-inch Sharp Memory LCD with 400 x 200 resolution User input – QWERTY tactile keyboard w/ backlight and touchpad based on Solder Party BB Q20 Keyboard USB – USB-C programming […]
