Overview Introduction The ESP32-S3-LCD-1.28 (referred to as the development board hereafter) is a low-cost, high-performance microcontroller development board designed by Waveshare. It features a 1.28-inch LCD screen, a lithium battery charging chip, and peripherals such as a six-axis sensor (three-axis accelerometer and a three-axis gyroscope). The board utilizes the ESP32-S3R2, an integrated system-on-chip (SoC) with low-power Wi-Fi and BLE5.0 capabilities. Additionally, it comes with an external 16MB Flash and 2MB PSRAM. The SoC includes hardware encryption accelerators, RNG (Random Number Generator), HMAC (Hash-based Message Authentication Code), and a Digital Signature module, meeting the security requirements of the Internet of Things (IoT). Its various low-power operating modes cater to power consumption needs in IoT, mobile devices, wearable electronics, smart homes, and other application scenarios.
