ESP32 Terminal–with ESP32 3.5 inch parallel 480x320 TFT capacitive touch RGB display(RGB by chip ILI9488)

Description

This Elecrow ESP32 terminal is a microcontroller based on the ESP32 master. It adopts Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240Mhz, supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), and can easily handle common edge terminal device application scenarios, such as industrial control, agricultural production environment detection and processing, intelligent logistics monitoring, smart home scenarios and more.

This ESP32 module also has a 3.5-inch parallel RGB interface capacitive touch screen with a resolution of 320*480 to ensure perfect image output at a frame rate (FPS) of 60. On the back of this terminal, we have introduced 4 Crowtail interfaces, which can be used with our Crowtail series sensors, plug and play, and create more interesting projects quickly and conveniently. In addition, it is also equipped with an SD card slot for extended storage (SPI leads) and a buzzer function. This ESP32 touchscreen supports ESP-IDF and Arduino IDE development and is compatible with Micropython/Arduino. It also supports LVGL, which is the most popular free and open-source embedded graphics library to create beautiful UIs for any MCU, MPU, and display type. Now it has also obtained the official certification of LVGL. LVGL's board certificate shows that the boards can be easily used with LVGL and has decent performance for UI applications.  The onboard charging circuit and lithium battery interface can use the type-c power supply interface to supply power and charge the battery at the same time, providing more outdoor scene expansion possibilities.

This ESP32 terminal uses an acrylic shell, which can not only protects the screen but also makes it more beautiful. The size is only pocket size, small and portable; two M3 fixing holes are easy to fix, making it easier for you to set up your project.

In addition, our other screen with SPI interface, while ensuring the basic visual effect, adds more Crowtail interface and Camera/microphone functions to it. For details, please click here.
