Buzzer Driver

Hardware version

MDD400 v3.0 — ESP32-P4 / MIPI-DSI / LVGL platform re-base. This board is at schematic-capture stage; no V3.0 hardware exists yet.

Other versions: v2.9 — fabricated prototype (current)

Under construction — V3.0 capture in progress

The V3.0 audio/alerting approach — the simple PWM buzzer versus PDM WAV playback — is an open design decision. This page is on hold pending that call.

This page will be generated from the V3.0 schematic during capture. See the Tasks page for status.
