Raspberry Pi 4: presentation

The famous microcomputer based on a simple ultra-compact motherboard has received an update of its components to offer more performance, while maintaining a low price to make it a multi-purpose engine. Home automation, multimedia or retrogaming, the Raspberr has become popular and its use has become very common among makers and robotics enthusiasts. Today, the Raspberry Pi 4 can become a small tool for machine learning, artificial intelligence, object and face recognition. The control of 3D printers or industrial production tools is also possible thanks to the new power of the small box.

The RP4 becomes compatible with the most recent standards and competes with traditional computers: it decodes 4K, connects via HDMI to a TV, can be woken up by PoE, is compatible with the latest Bluetooth 5.0 standard.

Available in 1, 2 or 4GB of RAM, the RaspberryPi4 expands its capacities to withstand more load or multiply roles. Home automation extends into your home and is always more resource-intensive, video decoding requires more CPU to read the h265 4K, so many reasons to switch to this new version, the most successful since the first generation released in 2012.

Raspberry Pi 4 Technical Setup

  • Broadcom BCM2711, ARM Cortex-A72 quad core 1.5GHz processor
  • VideoCore VI GPU
  • 1GB, 2GB or 4GB LPDDR4 RAM
  • microSD card reader
  • Micro HDMI port
  • 1 USB Type-C port; 2x USB 3.0; 2x USB 2.0
  • Gigabit Ethernet network card with PoE
  • WiFi 802.11b/g/n/ac
  • Bluetooth 5.0
  • CSI camera port
  • DSI display port
  • 3.5mm audio jack

In its reference configuration RPI4-MODBP-1GB (1GB of RAM), RPI4-MODBP-2GB (2GB) or RPI4-MODBP-4GB (4GB), the Raspberry Pi 4 embeds a VideoCore VI chipset that supports OpenGL ES 3.0 and decodes HEVC 4K. In theory, you can use two 4K screens on a RasPi4 but you will have to choose the 4GoRAM model and not want to decode 4K 60 Hz in fullscreenunder penalty of suffering delays.

The USB Type-C port is used to power the mini machine. The CSI port is for the Raspberry Pi 4 model B camera (there was no Model A this time around) and the DSI for connecting the Raspi4 touch screen.

The 4GB configuration will be more comfortable to accommodate an OS such as Windows 10 IoT Core on Raspberry Pi. Distributions Raspbian, RetroPie

The production of the RaspberryPi 4 must be ensured until January 2026, enough to give confidence to companies wishing to use it to sell home automation configurations, or other activity related to the nano-computer.
