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 […]

Sumolink Erhu RP2040 is a $3.60 Raspberry Pi Pico clone with a USB-C port

The Sumolink Erhu RP2040 is a Raspberry Pi Pico clone with the exact same features except the micro USB port has been replaced by a USB-C port that may be preferred by some people, and the Wisdpi claims it is one of the world’s cheapest RP2040 MCU boards at $3.60, although that price does not include shipping. We had seen some other replicas, but most offer something different rather than just the USB-C port. Two examples that come to my mind are the WeAct RP2040 with a USB-C port, but also a Reset button and up to 16MB SPI flash, instead of the 2MB flash in the original board, and the Banana Pi BPI-Pico-RP2040 with an extra I2C connector and an RGB LED. Sumolink Erhu RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash (Note: the specs list […]

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 […]

EDATEC ED-IPC2010 – A compact DIN Rail mountable industrial computer based on Raspberry Pi CM4

DIN Rail Raspberry Pi CM4 industrial computer

EDATEC has launched yet another Raspberry Pi CM4-powered industrial computer with the ED-IPC2010 offering a more compact design than the company’s CM4 Industrial and CM4 Sensing models, and an aluminum alloy enclosure that can easily be mounted to a DIN Rail. Most of the specifications of the new ED-IPC2010 are pretty common with a choice of Raspberry Pi Compute Modules 4 with up to 8GB RAM, 32GB flash, and optional WiFi 5 and Bluetooth 5.0, as well as a full-size HDMI video output, a Gigabit Ethernet port, and a few USB ports. What’s a little different is one FPC connector on the mainboard with both HDMI and USB for touchscreen displays. ED-IPC2010 specifications: SoM – Raspberry Pi CM4 SoC – Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5GHz with VideoCore VI GPU System Memory – 1GB, 2GB, 4GB, or 8GB RAM Storage – 8GB, 16GB, or 32GB eMMC flash Wireless – […]

Lichee Pi 4A RISC-V SBC takes on Raspberry Pi 4 with TH1520 processor

Lichee Pi 4A is a single board computer (SBC) powered by Alibaba T-Head TH1520 quad-core RISC-V Xuantie C910 processor @ 2.0 GHz with an Imagination GPU and a 4 TOPS NPU for AI that can compete against the Raspberry Pi 4 in terms of performance and features. We previously mentioned the Lichee Pi 4A (LPi4A) in our article about the Sipeed LM4A RISC-V system-on-module, but at the time we only had some benchmarks for the board and no photos and specifications about the SBC. Sipeed has now released photos, published detailed specifications, and is taking orders for the board. So let’s have a closer look. Lichee Pi 4A specifications against the ones for Raspberry Pi 4. The TH1520 used to be advertised at up to 2.5 GHz, but it seems to have now come down to 2.0 GHz. Software support will include Debian, OpenWrt, and Android which should then […]

PicoVNA 5 software for vector network analyzers supports Windows, Linux, MacOS, and Raspberry Pi

Pico Technology has released PicoVNA 5 control software for their vector network analyzers for Windows x86 64-bit, Mac, Linux x86 64-bit, and Raspberry Pi 3 and greater single board computers, superseding the Windows-only PicoVNA 3 software. As a Ubuntu user, I hate it when some hardware tool forces me to install software on Windows when there’s no Linux alternative, so any company that provides cross-platform tools is making the right move. I’m also not quite sure what a “vector network analyzer” (VNA) is, so I’ll first look into the PicoVNA 106 and PicoVNA 108 6/8.5 GHz VNAs from the company. PicoVNA 106/108 vector network analyzers highlights and specifications: Frequency ranges PicoVNA 106 – 300 kHz to 6 GHz PicoVNA 108 – 300 kHz to 8.5 GHz Up to 5500 dual-port S-parameters per second > 10 000 S11 + S21 per second Quad RX four-receiver architecture Up to 124 dB dynamic […]
