This is a fun project I made to play with the ESP32 C3 microcontroller and a round 1.28 inch TFT IPS display.
The SKU of this unit is ESP32-2424S012C-I. It uses a 240 by 240 pixel display with a GC9A01 driver. The board has a 3.3V regulator and a USB-C connector for power and programming.
The core is an ESP32-C3-MINI-1U module, a 32-bit RISC-V single-core processor, up to 160MHz. The board has 4MB of flash memory and 384KB of ROM. 400Kb of SRAM is available for the user. 8Kb of RTC memory is also available. The board has a 2.4GHz WiFi and Bluetooth 5.0.

#define LV_USE_FS_FATFS 1Needs to be changed to
#define LV_USE_FS_FATFS 0This board doesn't have an SD card reader or internal flash that can be accessed.
The ESP32 is partitioned as a Huge APP preset with 3Mb of application memory and 1Mb of SPIFFS for storage. It is also a good idea to change
#define LV_BUILD_EXAMPLES 1to
#define LV_BUILD_EXAMPLES 0That will avoid building all lvgl examples and save a lot of time compiling.
Unless you want to compile the examples just as the factory demo does.
