Most readers certainly know the single-board computer Raspberry Pi. It is less known Raspberry Pi Compute Module 4, a powerful computing unit based on the same architecture as Raspberry Pi 4, but designed for more industrial and commercial use. Compared to a “traditional” Raspberry Pi, the Computer Module (CM) offers greater flexibility and adaptability.
Raspberry Pi CM 4 uses the Broadcom BCM2711 SoC, supports hardware acceleration, including standards such as OpenGL ES and Vulkan, supports display on high-speed screens high resolution, with the ability to manage dual-screen configurations up to 4K. On the side of video decoding, CM 4 supports H.265 (HEVC) and H.264 standards. As regards connectivity, it integrates WiFi 802.11 ac (2.4 and 5 GHz), Bluetooth 5.0 and BLE, with the possibility of possibly using an external antenna.
Building a powerful HDMI stick with Raspberry Pi Compute Module 4 and PiPocket
Precisely using the Raspberry Pi Compute Module 4 board as a basis, piPocket aims to transform any television screen or monitor into a complete smart computer. The idea is to create a HDMI stick totally independent, requiring only a USB-C power source.
So it becomes possible to use the piPocket “envelope”, currently presented as a project in crowdfunding on Kickstarter, to access the main video streaming platforms such as Netflix and Prime Video, to access your media archive with Kodito run retro video games with RetroPie and much more.
piPocket is equipped with a IR receiver, which allows you to use a remote control or other infrared devices to control your Raspberry device. The connectivity options They also include HDMI, Micro SD card, USB-C and USB 2.0 ports, offering a wide range of opportunities to connect various devices and peripherals.
A device like piPocket, combined with the Raspberry Pi Compute Module 4 board, finds multiple application fields making any screen equipped with a porta HDMI smarter, more versatile and easier to use input. It is especially useful for those who need a compact and portable solution to manage presentations or even for daily use: in the end, you are faced with a versatile Mini PC of ultra-compact dimensions.
