Waveshare ESP32-S3-Touch-LCD-1.28
Overview
The ESP32-S3-Touch-LCD-1.28 is an ESP32S3 development board from Waveshare with a round LCD, suitable to build watches or similar projects. This board integrates complete Wi-Fi and Bluetooth Low Energy functions, an accelerometer and gyroscope, a battery charger and GPIO extension port.
Hardware
ESP32-S3 is a low-power MCU-based system on a chip (SoC) with integrated 2.4 GHz Wi-Fi and Bluetooth® Low Energy (Bluetooth LE). It consists of high-performance dual-core microprocessor (Xtensa® 32-bit LX7), a low power coprocessor, a Wi-Fi baseband, a Bluetooth LE baseband, RF module, and numerous peripherals.
ESP32-S3-Touch-LCD-1.28 includes the following features:
Dual core 32-bit Xtensa Microprocessor (Tensilica LX7), running up to 240MHz
Additional vector instructions support for AI acceleration
2MB of SRAM
16MB of FLASH
Wi-Fi 802.11b/g/n
Bluetooth LE 5.0 with long-range support and up to 2Mbps data rate
Round 1.28” LCD with touchscreen controller
Accelerometer/gyroscope
Battery charger
Digital interfaces:
6 programmable GPIOs
2 open-drain outputs
Low Power:
Power Management Unit with five power modes
Ultra-Low-Power (ULP) coprocessors: ULP-RISC-V and ULP-FSM
Security:
Secure boot
Flash encryption
4-Kbit OTP, up to 1792 bits for users
Cryptographic hardware acceleration: (AES-128/256, Hash, RSA, RNG, HMAC, Digital signature)
Asymmetric Multiprocessing (AMP)
ESP32-S3 allows 2 different applications to be executed in ESP32-S3 SoC. Due to its dual-core architecture, each core can be enabled to execute customized tasks in stand-alone mode and/or exchanging data over OpenAMP framework. See IPC Samples folder as code reference.

Building & Flashing
ESP-IDF bootloader
The board is using the ESP-IDF bootloader as the default 2nd stage bootloader. It is build as a subproject at each application build. No further attention is expected from the user.
