== Technical overview ==
* 13.3-inch IPS panel with a resolution of 1920 x 1080 pixels.
* Embedded Raspberry Pi 3A+ as the controller platform: 64-bit processor with four cores at 1.4 GHz, dual-band Wi-Fi, and Bluetooth 4.2.
* Toughened glass capacitive touch panel with 6H hardness and support for up to 10-point multitouch.
* Built-in speaker, MEMS silicon microphone, and 3.5 mm audio jack.
* Voice control via the Snowboy speech model; the device recognizes the wake word “smart mirror” and emits an audible signal.
* Mounting holes on a 75 x 75 mm grid (M4); the package includes a stand with a 75° tilt angle.
* Difference from the Magic Mirror variant: The Magic Mirror uses one-way mirrored glass, whereas the PiPad uses toughened glass.
* Pre-configured images already include the required libraries and drivers; after booting, the application runs automatically.
* Manual installation requires adding hdmi_group=2, hdmi_mode=82, and hdmi_cvt 1920 1080 60 6 0 0 0 to config.txt.
* For audio setup, the WM8960 sound card driver is installed via the waveshare/WM8960-Audio-HAT repository and then verified with sudo dkms status.
* The Google Assistant service is limited to 500 requests per day; configuration requires an OAuth client ID file, registration of a device model, and authorization via google-oauthlib-tool.

== Notes and version constraints ==
* The source contains placeholders such as {{{name2}}} and {{{userDefinedInfo}}}, indicating incomplete templates; these fields must be replaced with concrete values before publication.
* The described steps are version-sensitive: Node.js 10.x, specific kernel versions (e.g., 4.19.58-v7l+), and path names may vary depending on the OS image.
* The Google Assistant service has a daily request limit of 500 requests; this must be considered for production use.
* The Snowboy model must be downloaded and copied into the ~/MagicMirror/modules/MMM-VoiceAssistant/pi directory; the exact model file is not explicitly named in the source.
* Power supply is via a 12 V / 1 A adapter with outer diameter 3.5 mm and inner diameter 1.35 mm; alternative power supplies must keep ripple within ±5 %.
* Some instructions reference external URLs (Google Drive, GitHub, Nodesource) whose availability is not guaranteed.
* The source mentions CE and RoHS certifications under “Authentication Information” but provides no details on certificates or test reports; this should be verified before release.
