The ESP32-2424S012 is an ESP32-C3 WiFi and BLE development board featuring a 1.28-inch round touchscreen color display, all enclosed in a sleek black or white plastic casing. It is compatible with Arduino and the LVGL library. Additionally, it has been successfully used with Tasmota and ESPHome firmware, as we will discuss further below.
In previous articles, we have explored various compact ESP32-S3/ESP32-C3 boards with round displays, including the LILYGO T-RGB ESP32-S3 board, Makerfabs’ “ESP32-S3 Round SPI TFT with Touch 1.28″, and SB Components’ Dual Roundy. However, these options either lack a full case or only have a front cover, leaving the back exposed. The ESP32-2424S012 stands out as it comes with a case that covers both the front and back, featuring openings for expansion connectors.
