Amidst some rumors of a long-time update, the Raspberry Pi 4 made now available carrying some great upgrades.
Going back from 2012, we could recall Raspberry Foundation launching its first-ever Raspberry Pi 1 has only 26 pins. Three years later when the version upgraded into Raspberry Pi 2. Rumors say that the foundation would take a while before a major Raspberry Pi upgrade, but it’s now made available starting on June 24th.
The physical design of the Raspberry Pi 4 Model B does not veer away from the design of the Raspberry Pi 3 Model B+. It’s still a single-board computer with numerous pin connectors that is the size of a deck of cards.
The design might be similar but the performance varies a lot, various updates were done in the 4th generation model. It begins with a faster system-on-a-chip. A Cortex-A72 architecture (quad-core 64-bit ARMv8 at 1.5GHz) was used in this set. It supports H.265 hardware video decoding for instance.
The Raspberry Pi foundation has established a stuck of 512MB or 1GB of RAM for years. Breaking this, users can now avail models with much more memory as needed. The base model would still start with 1GB of RAM. But optionally, the models would be sold depending on your needs choosing from 2GB RAM or even 4GB of RAM.
Its raw memory capacity transfer speeds now become faster since the foundation is switching from LPDDR2 to LPDDR4.
In terms of its connectivity, there is now a real Gigabit Ethernet, instead of Ethernet over USB 2.0. In this case, a model should open a ton of potential use cases for servers and headless Raspberry Pi devices.
In addition to those updates, there are now two USB 3.0 ports and two USB 2.0 ports. You also get a USB-C port for the power brick. There is also an update to its new Bluetooth 5.0 from Bluetooth 4.2.
The full-size HDMI port in the hardware is now gone. Instead, there are now two micro-HDMI ports, that allow plugs up to two 4K displays at 60 frames per second using one Raspberry Pi.
There’s a microSD card slot for the operating system and user data on a memory card. There are still 40-pin GPIO header compatible to any boards.
The base model costs $35, while the 2GB RAM model costs $45 and the 4GB RAM model costs $55.
This update promotes using the units, allowing faster and wider accessibility to its users.
