MaTouch ESP32-S3 7” Parallel TFT with Touch

Introduction

The 7-inch screen uses the esp32-s3 chip as the controller and also includes the audio function. The TF card solves the problem of audio and picture storage, and it also has an expandable io port, and there is also a 16G SD card in the display, so customers do not need to bother purchasing the SD cards. Therefore, such a product is very suitable as a Screen display solution for IoT. At the same time, we have configured two different resolution versions for selection to meet the screen display requirements under different needs.

Model:MTESPS37

Usage

Due to the 7" screen working current needs to be greater than 600mA, if users found that the screen continues to restart after the program upload is finished, it may be the current is not enough to drive the board. Please check whether the input current meets the requirements.

To ensure the running environment, the same version is recommended.

Note: When users use the MaTouch ESP32-S3 Parallel 7-inch TFT with Touch, It has two versions with different resolutions, and the demos used need to modify the corresponding macro definition to run well， please attention to the version of the resolution.please attention to the version of the resolution.

#define SCREEN_HD    //1024*600
// #define SCREEN_NORMAL     //800*480
