Suntun ESP32 Round is a development board that integrates an ESP32-C3 along with a 1.28” round IPS touchscreen.
Previously, we had seen in this entry the series of Sunton development boards that mount 2.8” or 3.2” rectangular displays, as very interesting and low-cost devices.
This time we see a similar development from the same manufacturer Sunton, but this time it mounts a round display. The truth is that round displays have a special “something” that makes them particularly attractive.
In this case, we find a 1.28” round IPS display with 240x240 pixels, with high brightness and viewing angle. Optionally, there is the possibility to choose it with a capacitive touch panel.
Furthermore, the models with a touch panel include a plastic case, available in black or white. The case gives it a very professional and durable look, and is much more suitable for real projects.

For programming, of course, like all ESP32s, it is compatible with the Arduino environment. Therefore, it is very easy to incorporate into our DIY projects.
Regarding the price, we can find it from international sellers like Aliexpress for €14 for the model without a touch panel, and €18 for the model with a capacitive touch panel and plastic case, in both cases including shipping.
As we can see, it is a very complete board at a very interesting price, and probably one of the best options for incorporating a round display into our projects.
