Olimex RP2040-PICO-PC “computer” to feature RP2040-Py Raspberry Pi Pico compatible module

RP2040-PICO-PC board

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 external modules or sensors from Olimex Grove compatible 4-pin JST2.0 […]

Raspberry Pi RP2040 boards are coming with… HDMI?

Raspberry Pi RP2040 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 Raspberry Pi Zero form factor with a 40-pin GPIO header, […]

RK628D adds HDMI input, extra video outputs to Rockchip processors

RK628D HDMI Input chip

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 (yuv420) – Support 8-/10-bit, RGB888/YUV420, EDIC and CEC. Parallel RX […]

Android 11 on Android TV Launches for the Big Screen

Android 11 for Android TV

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 mode for system updates, inactivity prompts, and OEM configurable wake […]

Rock Pi 4C SBC with 4GB RAM, HDMI and DisplayPort Launched for $59 and up

Buy Rock Pi 4C

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 to 1.4 GHz Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1/3.2, Vulkan […]
