| **Required breakout rework:** The Adafruit 3006 breakout (and clones) includes a 1 MΩ SMD pull-up between ''SD_MODE'' and the chip's V_DD (5 V). This must be **desoldered from each breakout before installation** — otherwise the GPIO LOW state would fight the pull-up and shutdown never engages. Once removed, only the chip's internal 100 kΩ pull-down remains. | **Required breakout rework:** The Adafruit 3006 breakout (and clones) includes a 1 MΩ SMD pull-up between ''SD_MODE'' and the chip's V_DD (5 V).

| - | **Do NOT bridge any breakout channel-selection solder jumpers** (''L'', ''R'', ''Mono''). If bridged, they hard-tie ''SD_MODE'' to the chip's 5 V VDD, and driving the GPIO LOW would short 5 V to GND through the 3.3 V GPIO pin and damage the Teensy. | ||
