What an energy-efficient, silent (without fan), most cost effective machine it is!!! Upgraded CPU and memory options make the new Pi advanced in the family of Pi versions.
The Raspberry Pi 4 Model B gets a boost of speed and performance. It comes with a new Broadcom 64 bit SoC processor running at 1.5 GHz, memory (RAM) options upto 4GB, 2 USB 3.0 ports, Gigabit Ethernet and dual 4K micro HDMI ports (for two monitors at the same time!). All this results in a new platform which offers users more options to play with higher-memory, low-cost computing.
By looking for the unexpected and unrevealed the surreptitious features in the Raspberry Pi 4
