Raspberry Pi 4 Computer Model B - 2GB RAM
1 Introduction
The Raspberry Pi 4 Model B (Pi4B) is the first of a new generation of Raspberry Pi computers supporting
more RAM and with siginficantly enhanced CPU, GPU and I/O performance; all within a similar form
factor, power envelope and cost as the previous generation Raspberry Pi 3B+.
The Pi4B is avaiable with either 1, 2 and 4 Gigabytes of LPDDR4 SDRAM.
