ESP32-S3 Parallel 4.0" TFT with Touch

introduction

ESP32-S3 Parallel 4.0 TFT with Touch is a new solution for IoT application, Choose the ESP32-S3, whicn is a execllent performance controllter. Compare with ESP32-S3 4.3 inch IPS display it increase the I2S output. In many IoT scenarios, Audio playing can have a better exhibition effect. by integrating display/ touch/ audio speaker/ Lipo charger, to make this product ideal for applications such as IoT controlling, electronic photo frame, etc.
