CrowPanel ESP32 Terminal with 3.5-inch RGB Display¶
Description¶
The CrowPanel ESP32 Terminal is a microcontroller based on the ESP32 S3. 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 terminal also has a 3.5-inch parallel RGB interface capacitive touch screen with a resolution of 480*320 to ensure perfect image output at a frame rate (FPS) of 60.
On the back of this terminal, there are 4 Crowtail interfaces, which can be connected with the 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. 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 terminal uses an acrylic shell, which can not only protects the screen, but also makes it more beautiful. The size is only a pocket size, small and portable; two M3 fixing holes are easy to fix, making it easier for you to set up your project.
It support ESP-IDF and Arduino IDE development, and is compatible with Python/Micropython/Arduino. It also support LVGL, which is the most popular free and open-source embedded graphics library to create beautiful UIs for any MCU, MPU and display type.
