Raspberry Pi 4 WiFi Fails When Setting HDMI to 2560×1440 Resolution

Raspberry Pi 4 WiFi Fail 2560x1440 Resolution

Enrico Zini was working on a digital signage solution based on Raspberry Pi 4, then he set the video output to 2560×1440, and all hell broke loose. And by that, I mean WiFi stopped working. It was not obvious at first but after a full day of debugging, trying both micro HDMI outputs, different HDMI cables, three different Raspberry Pi boards, different power adapters, Raspbian Buster and Buster Lite, different MicroSD cards… He could reproduce the problem in all conditions, all he needed to do was to set the resolution to 2560×1440, and WiFi would just stop working. Setting the resolution to 2048×1080 or lower, and all WiFi connectivity issues disappeared. He did not test at higher resolutions, and another user reported a similar problem happening at 2.4 GHz, but not at 5 GHz, albeit when setting HDMI output to 1920×1080. So it looks like interference, but as noted by […]

Arbor M1016 10.1″ Medical-Grade Tablet Targets Infotainment & Kiosk Applications

Arbor M1016 Healthcare & Kiosk Tablet Arbor offers various products in the embedded systems field, automotive IoT and healthcare infotainment, as well as patient interfaces for hospitals. The M1016, a 10.1″ Healthcare Infotainment Terminal is a soon to be released alternative to the company’s HTab. Previous Articles for Arbor HTab healthcare bedside patient entertainment tablet and the IoT-800N Automotive Panel PC have both been reported on in previous articles about Arbor market entrants. The Basics and Kiosk Design The M1016 runs an Arm Cortex-A35 CPU @ 1.5GHz, that supports Android 8.1, and offers a variety of features for many of the different capabilities of patients under care. The design is based on a Kiosk model, with an a-la-carte menu arrangement. Access and Power Consumption The unit itself is fanless with low power requirements that lend themselves well to thin enclosure design and ease of use. The GPU is a Mali-G31 […]

Beelink GT-King and GT-King Pro Android 9.0 TV Boxes to Ship with an 8GB CoreELEC MicroSD Card

Beelink GT-King is a TV box based on Amlogic S922X Cortex-A73/A55 processor, while GT-King Pro is an updated version with Amlogic S922X-H processor that adds Dolby and DTS licenses. Both models ship with Android 9.0 operating system. But Kodi 18.4 based CoreELEC 9.2.0 Linux OS released last September supports various Amlogic S905X2/S922X/A311D devices including Khadas VIM3 SBC and Beelink GT-King TV boxes. That means you should be able to download CoreELEC and flash it to a MicroSD card to run either Android 9.0 from the eMMC flash or CoreELEC on the SD card. But Beelink posted on Freaktab forum that they’d ship Beelink GT-Link and GT-King Pro TV with an 8GB MicroSD Card pre-loaded with CoreLEC to allow for dual-boot systems. So you’d know even need to do anything. One way to select between CoreELEC and Android is to insert or remove the MicroSD card before booting, but it’s not […]

Hacarus Embedded AI Computing Kit Leverages Sparse Modeling Technology

Hacarus AI Computing Kit Sparse Modeling Technology

AI training often requires thousands of samples to become accurate, and it can be costly and time-consuming, for example, if you want to train a model to detect manufacturing defects you’d need to provide images with both defective samples and good samples. Japanese AI experts at Hacarus have been working on a solution called Sparse Modeling which requires about 50 samples or even less for training, and worked with Congatec to provides an embedded AI computing kit leveraging the technology. Sparse Modeling Technology Hacarus does not go into great detail but explains Sparse Modeling technology is using a data modeling approach that focuses on identifying unique characteristics, in a way that humans recognize friends and family without having to look at everything from feet to head. That means algorithms based on Sparse Modeling do not need as much data as traditional AI solutions, leading to much smaller AI footprint suitable […]

esp32MX-E ESP32 Board Comes with Ethernet and USB-C Ports (Crowdfunding)

We’ve already covered several ESP32 boards with Ethernet including Olimex ESP32-GATEWAY and Silicognition wESP32, and I’ve just noticed Espressif also made its own with ESP32-Ethernet-Kit. Modtronix Engineering has another take with esp32MX-E board that beside Ethernet also exposes a USB-C port, a MicroSD card slot, and also adds an STM32F0 microcontroller acting as an I2C I/O expander. esp32MX-E specifications: Wireless Module ESP32 dual-core LX6 microprocessor at 160 or 240 MHz, 4 MB Flash, 520 KB SRAM Wi-Fi 4 802.11 b/g/n Bluetooth 4.2 BR/EDR & BLE Storage – MicroSD card slot USB – USB Type-C connector for programming, power, and Virtual COM port Expansion via 14-pin and 20-pin female headers 22x I/O pins of which 4 are inputs only. 4x 5 V tolerant I/O pins Not all I/Os are available when the SD Card is used Programmable pull-up and pull-down resistors on most inputs Secondary MCU – I²C I/O expander implemented […]
