We previously wrote it was possible to create a Raspberry Pi RP2040 board with HDMI using DVI and programmable IOs to output video up to 640×480 at 60 Hz with the microcontroller’s Cortex-M0+ cores clocked at 252 MHz. At the time, we also noted Olimex was working on such a board with RP2040-PICO-PC designed to create a small Raspberry Pi RP2040 computer with HDMI/DVI video output. The Bulgarian company has now manufactured the first prototype, but due to supply issues with the Raspberry Pi Pico board, they also designed their own RP2040-PICO module since they’ve got a reel of Raspberry Pi RP2040 microcontrollers. RP2040-PICO-PC small computer board Specifications: Support for Raspberry Pi Pico board Storage – MicroSD card Video Output – HDMI port with DVI signal (note no audio through this interface) Audio output – 3.5mm audio jack Expansion UEXT connector with UART, SPI, I2C, 3.3V, and GND to attach […]
Raspberry Pi RP2040 boards are coming with… HDMI?
We’ve already seen Raspberry Pi RP2040 MCU can support VGA output using the microcontroller’s programmable I/O blocks. But yesterday, I saw two upcoming RP2040 boards with an HDMI connector. How is that supposed to work? The first one is Olimex RP2040-PICO-PC that’s indeed like a pico PC board with an HDMI connector for video, a micro SD card for storage, a standard 3.5mm audio jack for speaker or headphone, and a USB host for a keyboard.

The second board, dcelectr DC2040, follows the […]
RK628D adds HDMI input, extra video outputs to Rockchip processors
If I’m asked about a Linux or Android platform with HDMI input, I would immediately think about Realtek RTD1295 SoC with products like Zidoo X9S or X2 TV stick which enabled picture-in-picture (PiP), UDP/TCP broadcast of HDMI input, or PVR functions. Some Rockchip boards such as Orange Pi RK3399 SBC do come with both HDMI output and HDMI input, with the latter relying on a Toshiba TC358749XBG HDMI interface bridge IC. But Rockchip has decided to design its own HDMI input chip with Rockchip RK628D supporting HDMI, parallel RGB or BT.1120 as input and dual MIPI, dual LVDS, GVI (general video interface), parallel RGB, or BT.1120 as outputs. The new chip would enable PCB designers to add display output ports to application processors such as RK3288 or RK3399, or add an HDMI input interface. Rockchip RK628D key features and specifications: Video input interfaces HDMI 1.4/2.0 RX interface up to 4Kp60 […]
Android 11 on Android TV Launches for the Big Screen
Android 11 may have been released for smartphones on September 8th, but Google has just only announced the launch of Android 11 on Android TV for an optimized experience on the big screen. The version of the TV-optimized operating system builds on the many new features introduced for Android 11, but also adds performance and privacy improvements, new features tailored for the TV, and updated developer tools. One of the notable TV-related improvements in Android 11 includes HDMI 2.1’s Auto Low Latency Mode (ALLM) which allows the latency setting to be automatically established depending on the applications, as for instance, many games require the lowest possible latency, while it’s not really an issue for movies and videos. Android 11 on Android TV also adds low latency media decoding, a new Tuner Framework with updated Media CAS support, extensions to the HAL implementation of HDMI CEC, extended gamepad support, silent boot […]
Rock Pi 4C SBC with 4GB RAM, HDMI and DisplayPort Launched for $59 and up
Last October, Radxa unveiled Rock Pi 4C SBC as an update to the company’s Rock Pi 4 SBC, with the same Rockchip RK3399 hexa-core processor, 4GB RAM, but instead of providing one HDMI output only, Rock Pi 4C board offers two video output just like Raspberry Pi 4 board, but with a twist, since it combines a micro HDMI port with a Mini DisplayPort connector. It’s all good except for one small detail. So far, it was not possible to purchase the board. The good news is that Radxa has now announced the availability of the board for just $59 on AllNetChina. You can also buy Rock Pi 4C on other platforms, but the price is much higher at $109.99 on Amazon, and $99.99 on Aliexpress. Rock Pi 4C specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 1.8 GHz, 4x Cortex-A53 @ up […]
$11 HDMI to USB 2.0 Video Capture Dongle Supports up to 1080p30 Resolution
Over the years we’ve covered several HDMI input solutions for PiP, video capture, and/or RTSP streaming and some of the most popular options where Realtek RTD1295 based TV boxes such as Zidoo X9S or LAKE I Home Cloud. But there’s now a more cost-effective option with “Camlink” HDMI to USB 2.0 converter which you can connect to your PC or single board computer. It’s compatible with UVC video class, supports up to 1080p30, and offers HDCP compatibility. Best of all it’s really cheap with pricing starting at around $11 on Aliexpress including free shipping and also available on eBay. Key features and specifications: HDMI input up to 4K resolution (3840×2160 @ 30 Hz) with 8/10/12 bit color depth support; Up to 15-meter cable (AWG26) Video Output up to 1080p30 using YUV or JPEG modes Audio – L-PCM Compatible with common video software such as VLC, OBS, Amcap, etc … Compliant […]
Amlogic S922X Digital Signage Board Comes with HDMI, LVDS, V-by-One, and eDP Video Interfaces
Thanks to its 4K video playback and output capability and high-speed interfaces such as PCIe, USB 3.0 and Gigabit Ethernet, Amlogic S922X is a suitable processor for 4K digital signage players. One way is to get a TV box optimized for signage applications such as Rikomagic MK25, but if you want to integrate a board into your own display, XYT-6689 SBC may be an interesting option with LVDS, V-by-One and eDP (embedded DisplayPort) display interfaces, as well as many other features. XYT-6689 S922X digital signage board specifications: SoC – Amlogic S922X hexa-core big.LITTLE processor with 4x Arm Cortex A73 cores @ up to 2.0 GHz, 2x Arm Cortex A53 cores, Arm Mali-G52MP6 (6EE) GPU; 12nm manufacturing process System Memory – 2GB or 4GB LPDDR4 Storage – 16GB to 64GB eMMC flash, microSD card slot up to 128 GB; maybe SATA (unsoldered “laptop” SATA interface on the backside of the board) […]
