Overview
Latest addition to the Raspberry Pi family is the all new tiny Raspberry Pi Zero 2 W & Zero 2 WH (with Header) which packs in RP3A0, a custom-built SIP (system-in-package) designed by Raspberry Pi in the UK which has a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz, integrating a Broadcom BCM2710A1 die with 512MB of SDRAM. The RP3A0 gives 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. Also let's not forget that we get this improved performance in the same form factor as Pi Zero and Pi Zero W which makes it compatible with Pi Zero cases.
The "W" appending the Pi Zero 2 W clearly implies that it has an on board 2.4GHz 802.11 b/g/n wireless LAN and Bluetooth 4.2 and support Bluetooth Low Energy (BLE).
The board has 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.
Mandatory Accessories for Zero 2 W
1. Power Supply (Micro-USB)
- 5V, minimum 2.5A recommended
- Micro-USB connector (not USB-C)
- Required to power the board reliably
2. microSD Card (with OS)
- 8GB minimum (16GB or higher recommended)
- Used to store the operating system and files
- Must be flashed with Raspberry Pi OS or compatible OS
3. Display Cable (Mini HDMI)
- Mini HDMI to HDMI cable or adapter
- Required if using an external monitor or TV
- Supports up to 1080p output
4. Input Device Support (USB OTG)
- Micro-USB OTG cable
- Needed to connect keyboard, mouse, or USB devices
- Essential for initial setup without SSH
