ESP32-S3 Round SPI 1.28" TFT with Touch
Introduction
The ESP32-S3 round display with touch can be a great tool for your applications such as smartwatch.
We selected the ESP32-S3 generation as the controller, with 16MB Flash and 8MB PSRAM, enough for most IOT applications; The round display is 240x240 resolution 1.28", colorful RGB, with capacitive touch, it communicates with ESP32 with SPI interface, so there enough GPIO left for expansion applications.
There 2 Mabee(Grove compatible) connectors, with standard GPIO and I2C bus, so users can freely to connect expansion modules for application development. Besides, 16G TF card is added to the board, for field application storage.
