== Summary ==<br />
The Waveshare Zero-to-Pi3 Adapter (B) allows a Raspberry Pi Zero 2W to be used on a board with the same interfaces as the Raspberry Pi 3 Model B/B+. It provides four USB ports, an Ethernet connection via an RJ45 port, and an HDMI output. It is designed exclusively for the Zero 2W; the older Zero is not supported.<br />

<br />
== Technical overview ==<br />
* Base module: Raspberry Pi Zero 2W featuring a Broadcom BCM2710A1 quad-core SoC (Arm Cortex-A53 @ 1 GHz), 512 MB LPDDR2 SDRAM, 2.4 GHz 802.11b/g/n Wi-Fi, and Bluetooth 4.2 with BLE.<br />
* Connection: Pogo pins plug directly into the Zero board, allowing it to mount without a connector.<br />
* Interfaces: Four USB 2.0/1.1 expansion ports, one RJ45 Ethernet port (10/100 Mbps using an RTL8152B chip), mini-HDMI output, micro-USB OTG port, microSD slot, 40-pin GPIO header, composite video pads, and reset pad.<br />
* Camera: CSI-2 camera interface available.<br />
* Media: H.264/MPEG-4 codec support at 1080p30, plus OpenGL ES 1.1/2.0 graphics.<br />
* Compatibility: Supports only the Raspberry Pi Zero 2W; the original Raspberry Pi Zero is explicitly unsupported.<br />
* Mechanical: Thread size PM2.5*4 for screwing the Pi onto the adapter.<br />
* Audio: Onboard USB audio headphone jack and additional speaker port.<br />
* Documentation: Schematic, Zero 2W datasheet, dimensions, and test introduction are linked in the resources section.<br />
* Software tools: Panasonic SD Formatter, Win32DiskImager, and PuTTY are mentioned as useful utilities.<br />

== Notes and version constraints ==<br />
* Compatibility applies only to the Zero 2W; the older Zero does not work with this adapter.<br />
* The Zero 2W's USB interface differs from the original Zero. If the mouse or keyboard stop responding, add the line `dtoverlay=dwc2,dr_mode=host` to /boot/config.txt.<br />
* Version-sensitive steps: The exact firmware/driver versions of the Zero 2W and the adapter should be confirmed before setup; the document does not state specific version numbers.<br />
* Adapter dimensions are not fully given in the provided text (only a link to the dimensions data).<br />
* No prices, stock levels, warranties, or safety certifications are mentioned in the source; these must not be added.<br />
