Powerful ESP32-S3 Terminal SPI 3.5″Inch TFT Touch Display for $39.90

With a strong ESP32-S3 chip, 2.4GHz Wi-Fi compatibility, and Bluetooth 5 (LE), this handheld terminal is built on the powerful ESP32 controller which offers enhanced computing and processing capabilities for IoT terminal applications. The ESP32-S3-N16RB module can lead to a variety of interfaces due to its scalability. It incorporates a MEMS microphone, camera interface, and buzzer function in addition to Crowtail’s digital port, analog port, UART, and IIC interface.

It has made it simple to recognize faces, objects, and scenes with the 2M pixel camera, and it allows for greater creativity in advanced applications like speech recognition and voice control. The 3.5-inch screen, which uses an SPI serial display with 320 x 480 resolution, is the finest option for a handheld or pocket terminal. The screen’s frame rate can reach 20FPS, which is adequate for the majority of application settings.



It is compatible with Python, MicroPython, and Arduino and facilitates the creation of ESP-IDF and Arduino IDE. Additionally, it supports LVGL, the most widely used free and open-source embedded graphics library for building stunning user interfaces for any MCU, MPU, and display type.
