Description
ESP32-C3-LCDkit is an evaluation development board based on ESP32-C3-Mini-1 chip and SPI interface display. The development board is equipped with a rotary encoder switch, which can realize screen interaction, with Bluetooth and WiFi functions, and supports audio playback and infrared wireless control. With its low cost, low power consumption, and powerful performance, ESP32-C3-Mini-1 meets the basic GUI interaction needs of users and supports LVGL graphics programming. It is widely used in smart homes, industrial automation, healthcare, and consumer electronics, especially for small-screen application scenarios.
ESP32-C3-LCDkit mainboard is the core of the whole kit. It integrates ESP32-C3-MINI-1 module, built-in 4 MB Flash and 400 KB SRAM, provides powerful processing power, and provides ports for connecting to LCD daughter board. ESP32-C3-LCDkit daughter board is equipped with a 1.28-inch LCD screen with SPI interface and resolution of 240x240, and the driver chip model is GC9A01. It is compatible with I2C and SPI interface screens, and can flexibly cope with various display requirements. The included rotary encoder switch supports key switches and 360° rotation for controlling the screen GUI. At the same time, the board also integrates an infrared module and speaker to support infrared wireless control and high-quality audio playback. The USB-C interface supports downloading and debugging operations, which is convenient for development and testing.
