Raspberry pi or RPI Zero 2W is the second generation Zero board released by the RPI foundation.
It has a 64 bit Quad-core CPU with four A53 cores clocked at 1 GHz and a 512 Mb LPDDR2 Ram clocked at 450 MHz. I
t’s worth mentioning that both of these are placed in a single SIP(system in package) chip called RP3-AU or RP3. In earlier models, the RAM is placed on top of the CPU i.e, system on a chip.
Apart from this, like previous boards, this new board has a 40 pins GPIO header, mini-HDMI, USB On-The-Go ports, and a camera connector.
