CrowPanel Pico Display-3.5 inch 480*320 HMI Module TFT LCD Touchscreen with RP2040 Support C/C++/LVGL

Description

CrowPanel Pico Display is an HMI module series that utilizes the powerful Raspberry Pi RP2040 (ARM Cortex-M0+) as its main controller. It is equipped with a 32-bit dual-core chip running at a clock frequency of up to 133 MHz. With 264kb of built-in SRAM and a 2MB flash memory chip, it integrates power supply, voltage regulation, and counter functions into a single microcontroller. This series of touch screens incorporate high performance, low cost, and user-friendly features.

The Pico 3.5” Display has a resolution of 480*320 and comes with a touch pen for flexible screen manipulation. It has flexible I/O peripherals and a unique programmable input/output (PIO) subsystem, including practical communication interfaces such as I2C, UART, common IO ports, and USB. It also features a lithium battery interface and a buzzer alarm, enabling communication with almost any external device. This provides professional users with flexibility and powerful expandability, allowing seamless connection to the physical world and control of various aspects of smart homes.

The module comes with abundant resources, including development SDK, and documentation. It has a very low entry barrier, making it suitable for beginners and hobbyist users. It supports C/C++ programming languages, is compatible with the Raspberry Pi ecosystem, and is suitable for the TensorFlow Lite open-source machine learning framework and the LVGL graphics library. It serves as an excellent platform for machine learning applications and is the preferred solution for Pico-like HMI interaction terminals.

OEM customization requests can be discussed for projects.
