Quick Start

This section describes how to get started with ESP32-S2-Kaluga-1. It consists of three parts: first, some basic information about ESP32-S2-Kaluga-1; then, the application development section describes how to initialize the hardware; and finally, how to burn firmware to ESP32-S2-Kaluga-1.

Overview

The ESP32-S2-Kaluga-1 mainboard is the heart of the kit. It integrates the ESP32-S2-WROVER module and is equipped with connectors to various expansion boards. The ESP32-S2-Kaluga-1 is a key tool for prototyping human-computer interaction interfaces.

The ESP32-S2-Kaluga-1 mainboard is equipped with several connectors that can be used to connect corresponding expansion boards:

Touch FPC Connector	The ESP-LyraP-TouchA expansion board can be connected via FPC cable.
Touch switch	Switching to the OFF direction configures GPIO1 to GPIO14 to connect to the touch sensor; switching to the ON direction configures GPIO1 to GPIO14 for other purposes.
3.2” LCD FPC Connector	It can be connected to a 3.2” LCD expansion board, such as ESP-LyraP-LCD32, via an FPC cable.

Expansion Board Compatibility

If you need to use multiple expansion boards at the same time, please check the following compatibility information first:

Expansion board combination	Multiplexing interface or pin	Reason for failure to run	Solution
8311A v1.3 + CAM v1.1	I2S Controller	ESP32-S2 has only one I2S interface, but both development boards need to use the I2S interface of ESP32-S2 for communication (ESP-LyraT-8311A uses standard mode; ESP-LyraP-CAM uses Camera protocol).	Use time-division multiplexing; or choose an audio expansion board that can be connected through other GPIOs or DAC.
TouchA v1.1 + LCD32 v1.2	IO11, IO6	Since pin IO11 is multiplexed, the touch action cannot be triggered; ESP-LyraP-LCD32 is not affected because its BLCT pin is disconnected from IO6.	Do not initialize the IO11 (NETWORK) pin of the ESP-LyraP-TouchA expansion board; or configure the BLCT pin of the ESP-LyraP-LCD32 expansion board to -1 (equivalent to not using BLCT).
8311A v1.3 + LCD32 v1.2	IO6	Configure the BK pin of the ESP-LyraP-LCD32 expansion board to -1 (equivalent to not using BK).	The BLCT pin of ESP32-S2-Kaluga-1 will be disconnected from IO6.
TouchA v1.1 + 8311A v1.3	BT_ADC pin of ESP-LyraT-8311A	ESP-LyraT-8311A needs to use the BT_ADC pin when initializing the 6 buttons, and ESP-LyraP-TouchA also needs to use the BT_ADC pin when completing touch actions.	If you want to use the 6 buttons of ESP-LyraT-8311A, do not initialize the IO6 (PHOTO) pin of ESP-LyraP-TouchA.
TouchA v1.1 + CAM v1.1	IO1, IO2, IO3	Due to pin multiplexing, they cannot be used simultaneously.	Do not initialize IO1 (VOL_UP), IO2 (PLAY), and IO3 (VOL_DOWN) of ESP-LyraP-TouchA.
TouchA v1.1 + LCD32 v1.2 + CAM v1.1	IO1, IO2, IO3, IO11	Due to pin multiplexing, they cannot be used simultaneously.	Do not initialize IO1 (VOL_UP), IO2 (PLAY), IO3 (VOL_DOWN), and IO11 (NETWORK) of ESP-LyraP-TouchA.
TouchA v1.1 + LCD32 v1.2 + 8311A v1.3	IO6, IO11	If you use the BT_ADC pin of ESP-LyraT-8311A to initialize the 6 buttons of the development board, other expansion boards cannot use IO6 and IO11.	Do not initialize IO11 (NETWORK) of ESP-LyraP-TouchA. Also, do not initialize IO6 (PHOTO) if you need to use BT_ADC.

In addition, all expansion boards and the JTAG interface share pins IO39, IO40, IO41, and IO42. Therefore, the following situations may interfere with JTAG operation:

Plug in the expansion board
