Overview Introduction The ESP32-S3-Touch-LCD-1.28-B (hereinafter referred to as "the development board") is a low-cost, high-performance microcontroller development board designed by Waveshare. It features a 1.28-inch capacitive touch LCD screen, a lithium battery charging chip, a six-axis sensor (three-axis accelerometer and three-axis gyroscope), and other peripherals. The board is based on the ESP32-S3R2, which is a system-on-chip (SoC) integrated with low-power Wi-Fi and BLE 5.0. It also includes an external 16MB Flash and 2MB PSRAM. The SoC features hardware encryption accelerators, RNG, HMAC, and digital signature modules, meeting the security requirements of the Internet of Things (IoT). Its various low-power operating modes are suitable for power requirements in IoT, mobile devices, wearable electronics, smart home applications, and other scenarios.
