Description

This handheld terminal is based on the ESP32 controller, equipped with a powerful ESP32-S3 chip, and supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), providing more powerful computing and processing capabilities for IoT terminal applications. It is suitable for various scenarios, such as industrial IoT control terminals, smart agricultural terminals, personal smart home monitoring terminals, and personal DIY projects.

Thanks to the scalability of the ESP32-S3-N16RB module, it can lead to various interfaces. It not only has Crowtail's digital port, analog port, UART, and IIC interface, but also integrates a MEMS microphone, camera interface, and buzzer function. It supports ESP-IDF and Arduino IDE development and is compatible with Python/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. With the 2M pixel camera, it can easily realize face/object/scene recognition and provide more creativity in cutting-edge projects such as speech recognition/voice control.

The equipped screen adopts SPI serial screen with 320*480 resolution, and the size of 3.5 inches is the best choice as a handheld/pocket terminal. The frame rate of the screen is up to 20FPS, which is sufficient for most application scenarios. If you have higher requirements for the screen, you can try this RGB screen.

The whole terminal is surrounded by a perfect acrylic shell, which makes the whole product look more beautiful. At the same time, it can also be fixed in other ways. With two M3 screw mounting holes, you can mount it on the wall or PLC rail.

Its compatibility with the Crowtail system can give your project an easier implementation method and the convenience of one-stop shopping.

• As a smart home central control screen, it can perform video surveillance and face recognition, allowing you to keep abreast of home dynamics.

Hardware Overview

• REST button. Press this button to reset the system.
• LiPo port. Lithium battery charging interface (lithium battery not included)
• BOOT button. Hold down the Boot button and press the RESET button to initiate firmware download mode. Users can download firmware through the serial port
• 5V Power/Type C interface. It serves as the power supply for the development board and the communication interface between the PC and ESP-WROOM-32.
