The Raspberry Pi Zero 2 W is the next iteration in the Pi Zero line that remains as one of the most affordable single-board computers on the market. The successor to the breakthrough Raspberry Pi Zero W, Raspberry Pi Zero 2 W is a form factor–compatible drop-in replacement for the original board.
The board incorporates a quad-core 64-bit Arm Cortex-A53 CPU, clocked at 1GHz. At its heart is a Raspberry Pi RP3A0 system-in-package (SiP), integrating a Broadcom BCM2710A1 die with 512MB of LPDDR2 SDRAM. The upgraded processor provides the Raspberry Pi Zero 2 W with 40% more single-threaded performance, and five times more multi-threaded performance, than the original single-core Raspberry Pi Zero.
The Raspberry Pi Zero 2 W offers 2.4GHz 802.11 b/g/n wireless LAN and Bluetooth 4.2, along with support for Bluetooth Low Energy (BLE), and modular compliance certification.
The board is equipped with a microSD card slot, a CSI-2 camera connector, a USB On-The-Go (OTG) port, and an unpopulated footprint for a HAT-compatible 40-pin GPIO header. It is powered via a micro USB socket. Video output is via a mini HDMI port; composite video output can easily be made available via test points if needed.
Sharing the same form factor as the original Raspberry Pi Zero, Raspberry Pi Zero 2 W fits inside most existing Raspberry Pi Zero cases.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Faster is better. The previous Pi Zeros were a little slow. This one is a great improvement!
This is the smallest most powerful device with WIFI and Bluetooth. Low power and potential for fast startups. I'm loving it.

I purchased 2 the first one was DOA I tried to reported and was told to go to the forum, to date It does not work it overheats
Sorry to hear that the device is not working properly. If you posted on the forums we can troubleshoot the unit and assist you to the best of our abilities. https://forum.sparkfun.com
It's running Octoprint for my Ender 3 v2 like a champ! My only complaint is I could only buy one. Don't question if you should buy one for your project, just do it!
