In this video, we use the @Raspberry Pi Zero 2 W to build a YouTube subscriber counter with a MAX7219-based 8-digit 7-segment display.

The Raspberry Pi Zero 2 W is the successor to the Raspberry Pi Zero W. Its RP3A0-AU CPU is a System-in-Package (SiP) combining a BCM2710A1 die with 512 MB of RAM. So, the Zero 2W is a quad-core ARM Cortex-A53 Raspberry Pi 3 like board whereas the Zero W is a single-core ARM11 Raspberry Pi 1.

In many cases, the Zero 2 W can be used as a drop-in replacement for the Zero W and when doing so it will greatly speed up the host application. It is about 5 times as fast as a Zero W. According to Raspberry Pi, the Zero 2 W has about 85% of the performance of a Raspberry Pi 3.
