ESP32-S3 LCD Driver Board supports both circular and square displays

Waveshare ESP32-S3 LCD Driver Board is a compact development board designed to simplify the GUI development process. The company mentions that the board supports 2.1-inch, 2.8-inch, and 4-inch displays and with an additional SPI and I2C header it can support a wide range of LCD panels. Additionally, the board features an onboard lithium battery charger and 15 usable GPIO pins for added flexibility. These features make this device suitable for applications like smart home devices, industrial control panels, and interactive kiosks.

It seems like the board supports the 4-inch LF40 square touchscreen display that we wrote about just yesterday. other than that it also supports 2.1-inch and 2.8-inch circular displays. Seeking off circular displays, we have previously written about some ESP32-powered development boards with circular displays like the Waveshare 1.69-inch IPS touch LCD, the Waveshare RP2040-LCD-0.99-B, the Waveshare ESP32-S3-LCD-1.28 and many other types of displays. Feel free to check those out if you are looking for some unique display products.
