311
312   * - Boards Used
313     - HW Conflict
314     - Limitations
315     - Solution
316   * - 8311A v1.3 + CAM v1.1
317     - I2S Controller
318     - ESP32-S2 has only one I2S interface. But both extension boards require connection via the ESP32-S2's I2S interface (LyraT-8311A in Standard mode, ESP-LyraP-CAM in Camera mode).
319     - Utilize time division multiple access, or use a different audio module that can be connected via other GPIOs or DAC.
320   * - TouchA v1.1 + LCD32 v1.2
321     - IO11, IO6
322     - Touch actions cannot be triggered because of the multiplexed pin IO11. ESP-LyraP-LCD32 will not be affected because its BLCT pin will be disconnected fron IO6.
323     - Do not initialize IO11 (NETWORK) for your ESP-LyraP-TouchA, or configure the BLCT pin to `-1` (= do not use BLCT) for your ESP-LyraP-LCD32.
324   * - 8311A v1.3 + LCD32 v1.2
325     - IO6
326     - BLCT pin of ESP32-S2-Kaluga-1 will be disconnected from IO6.
327     - Configure the BK pin to `-1` (= do not use BLCT) for your ESP-LyraP-LCD32.
328   * - TouchA v1.1 + 8311A v1.3
329     - Pin BT_ADC on ESP-LyraT-8311A
330     - This pin is required for initialization of the six button on ESP-LyraT-8311A. At the same time, ESP-LyraP-TouchA needs this pin for its touch actions.
331     - If you plan to use buttons on ESP-LyraT-8311A, do not initialize pin IO6 (PHOTO) for your ESP-LyraP-TouchA.
332   * - TouchA v1.1 + CAM v1.1
333     - IO1, IO2, IO3
334     - Cannot be used simultaneously because of the mentioned multiplexed pins.
335     - For ESP-LyraP-TouchA, do not initialize IO1 (VOL_UP), IO2 (PLAY), and IO3 (VOL_DOWN).
336   * - TouchA v1.1 + LCD32 v1.2 + CAM v1.1
337     - IO1, IO2, IO3, IO11
338     - Conflicts on the mentioned multiplexed pins.
339     - For ESP-LyraP-TouchA, do not initialize IO1 (VOL_UP), IO2 (PLAY), IO3 (VOL_DOWN), and IO11 (NETWORK).
340   * - TouchA v1.1 + LCD32 v1.2 + 8311A v1.3
341     - IO6, IO11
342     - If ESP-LyraT-8311A's pin BT_ADC is used to initialize the board's six buttons, IO6 and IO11 will not be available for the other boards.
343     - Do not initialize IO11 (NETWORK) for your ESP-LyraP-TouchA. Also, if you need to use BT_ADC, do not initialize IO6 (PHOTO).
