* - Guard Ring
- Connected to a touch sensor, the guard ring triggers an interrupt if wet (Water rejection). It indicates that the sensor array is also wet and most (if not all) touchpads are unusable due to the false detection of touches. After receiving this interrupt, the user might consider disabling all the touch sensors via software.

Compatibility of Extension Boards
---------------------------------
If you want to use more than one extension board at the same time, please check the table given below.
.. list-table::
:widths: 20 10 30 40
:header-rows: 1
* - Boards Used
- HW Conflict
- Limitations
- Solution
* - 8311A v1.2 + CAM v1.0
- I2S Controller, IO46
- ESP32-S2 has only one I2S interface. But both extension boards require connection via the ESP32-S2's I2S interface (ESP-LyraT-8311A in Standard mode, ESP-LyraP-CAM in Camera mode). If IO46 is used by both extension boards at the same time, ESP-LyraP-CAM experiences interferences when used.
- No ready solution for now.
* - TouchA v1.1 + LCD32 v1.1
- IO11, IO6
- Touch actions cannot be triggered because of the multiplexed pin IO11. ESP-LyraP-LCD32 is also affected because its BK (BLCT) pin is connected to pin IO6.
- Do not initialize IO11 (NETWORK) and IO6 (PHOTO) for your ESP-LyraP-TouchA.
* - 8311A v1.2 + LCD32 v1.1
- IO6
- The two extension boards can be used at the same time. However, since the BK (BLCT) pin of ESP32-S2-Kaluga-1 is connected to IO6, ESP-LyraT-8311A's pin BT_ADC cannot be used and the board's six buttons will not be available.
- There is a solution that will allow you to use ESP-LyraT-8311A's pin BT_ADC, but will stop you from controlling the display background brightness with software: on your ESP-LyraP-LCD32 board, remove R39, change R41 to 100 Ohm, switch BLCT_L to on.
* - TouchA v1.1 + 8311A v1.2
- Pin BT_ADC on ESP-LyraT-8311A
- The two extension boards can be used at the same time. However, ESP-LyraP-TouchA cannot be triggered if ESP-LyraT-8311A's pin BT_ADC is used to initialize the board's six buttons.
- If you plan to use ESP-LyraT-8311A's pin BT_ADC, do not initialize pin IO6 (PHOTO) for your ESP-LyraP-TouchA.
* - TouchA v1.1 + CAM v1.0
- IO1, IO2, IO3
- Cannot be used simultaneously because of the mentioned multiplexed pins.
- For ESP-LyraP-TouchA, do not initialize IO1 (VOL_UP), IO2 (PLAY), and IO3 (VOL_DOWN).
* - TouchA v1.1 + LCD32 v1.1 + CAM v1.0
- IO1, IO2, IO3, IO6, IO11
- Conflicts on the mentioned multiplexed pins.
- **Solution 1**: For ESP-LyraP-TouchA, do not initialize IO1 (VOL_UP), IO2 (PLAY), IO3 (VOL_DOWN), IO6 (PHOTO) and IO11 (NETWORK). **Solution 2**: It will allow you to initialize IO6 (PHOTO) properly, but will stop you from controlling the background brightness with software. On your ESP-LyraP-LCD32, remove R39, change R41 to 100 Ohm, switch BLCT_L to on.
* - TouchA v1.1 + LCD32 v1.1 + 8311A v1.2
- IO6, IO11
- IO11 is multiplexed; IO6 is also multiplexed stopping you from using ESP-LyraT-8311A's pin BT_ADC that is needed to initialize the board's six buttons.
- **Solution 1**: For ESP-LyraP-TouchA, do not initialize IO6 (PHOTO) and IO11 (NETWORK). Please note that the six buttons on ESP-LyraT-8311A still cannot be used. **Solution 2**: On your ESP-LyraP-LCD32, remove R39, change R41 to 100 Ohm, switch BLCT_L to on. For your ESP-LyraP-TouchA, do not initialize IO11 (NETWORK). If you want to use the six buttons on your ESP-LyraT-8311A, also do not initialize IO6 (PHOTO).
Also, all extension boards and the :ref:`JTAG interface <jtag-debugging-tip-jtag-pins-reconfigured>` share the same pins IO39, IO40, IO41 and IO42. For this reason, the following may disturb the JTAG operation:
* Plugging in any extension board
* Debugging an application that is using an extension board
Known Issues
============
.. list-table::
:widths: 22 24 32 22
:header-rows: 1
* - Hardware Issue
- Description
- Reason for Failure
- Solution
* - ESP-LyraP-CAM v1.0, pin IO45, IO46
- Flashing firmware might be impossible with the extension board connected to the main board.
- Incorrect timing sequence is fed to strapping pins IO45 and IO46 when the board is powered on. It stops the board from booting successfully.
- While flashing the main board, keep the extension board disconnected.
* - ESP-LyraP-CAM v1.0, pin IO45, IO46
- Rebooting the board by pressing Reset might not lead to desired results.
- Incorrect timing sequence is fed to strapping pins IO45 and IO46 when the board is powered on. It stops the board from booting successfully.
- No ready solution for v1.2. This bug is fixed in ESP32-S2-Kaluga-1 V1.3.
* - ESP-LyraT-8311A v1.2, pin IO46
- Flashing firmware might be impossible with the extension board connected to the main board.
- Incorrect timing sequence is fed to strapping pin IO46 when the board is powered on. It stops the board from booting successfully.
- While flashing the main board, keep the extension board disconnected.
* - ESP-LyraT-8311A v1.2, pin IO46
- Rebooting the board by pressing Reset might not lead to desired results.
- Incorrect timing sequence is fed to strapping pin IO46 when the board is powered on. It stops the board from booting successfully.

Getting Started
===============
This section describes how to get started with the ESP32-S2-Kaluga-1. It begins with a few introductory sections about the ESP32-S2-Kaluga-1, then Section `Start Application Development`_ provides instructions on how to do the initial hardware setup and then how to flash firmware onto the ESP32-S2-Kaluga-1.
Overview
--------
The ESP32-S2-Kaluga-1 main board is the heart of the kit. It integrates the ESP32-S2-WROVER module and all the connectors for extension boards. This board is the key tool in prototyping human-computer interaction interfaces.
The ESP32-S2-Kaluga-1 board has connectors for boards with:
- Extension header (ESP-LyraT-8311A, ESP-LyraP-LCD32)
- Camera header (ESP-LyraP-CAM)
- Touch FPC connector (ESP-LyraP-TouchA)
- LCD FPC connector (no official extension boards yet)
- I2C FPC connector (no official extension boards yet)

.. _user-guide-esp32-s2-kaluga-1-kit-ext-board-compatibility:
Compatibility of Extension Boards
---------------------------------
If you want to use more than one extension board at the same time, please check the table given below.
.. list-table::
:widths: 20 15 33 32
:header-rows: 1
* - Boards Used
- HW Conflict
- Limitations
- Solution
* - 8311A v1.3 + CAM v1.1
- I2S Controller
- 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).
- Utilize time division multiple access, or use a different audio module that can be connected via other GPIOs or DAC.
* - TouchA v1.1 + LCD32 v1.2
- IO11, IO6
- 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 from IO6.
- 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.
* - 8311A v1.3 + LCD32 v1.2
- IO6
- BLCT pin of ESP32-S2-Kaluga-1 will be disconnected from IO6.
- Configure the BK pin to `-1` (= do not use BLCT) for your ESP-LyraP-LCD32.
* - TouchA v1.1 + 8311A v1.3
- Pin BT_ADC on ESP-LyraT-8311A
- 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.
- If you plan to use buttons on ESP-LyraT-8311A, do not initialize pin IO6 (PHOTO) for your ESP-LyraP-TouchA.
* - TouchA v1.1 + CAM v1.1
- IO1, IO2, IO3
- Cannot be used simultaneously because of the mentioned multiplexed pins.
- For ESP-LyraP-TouchA, do not initialize IO1 (VOL_UP), IO2 (PLAY), and IO3 (VOL_DOWN).
* - TouchA v1.1 + LCD32 v1.2 + CAM v1.1
- IO1, IO2, IO3, IO11
- Conflicts on the mentioned multiplexed pins.
- For ESP-LyraP-TouchA, do not initialize IO1 (VOL_UP), IO2 (PLAY), IO3 (VOL_DOWN), and IO11 (NETWORK).
* - TouchA v1.1 + LCD32 v1.2 + 8311A v1.3
- IO6, IO11
- 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.
- Do not initialize IO11 (NETWORK) for your ESP-LyraP-TouchA. Also, if you need to use BT_ADC, do not initialize IO6 (PHOTO).
Also, all extension boards and the :ref:`JTAG interface <jtag-debugging-tip-jtag-pins-reconfigured>` share the same pins IO39, IO40, IO41 and IO42. For this reason, the following may disturb the JTAG operation:
* Plugging in any extension board
* Debugging an application that is using an extension board
Hardware Revision Details
