RP2350 7-inch LCD Development Board 800x480 with touch support - Waveshare 33488

Description

Waveshare 33488 is a standalone development board based on the RP2350B microcontroller, equipped with an integrated 7-inch touch LCD display with a resolution of 800 x 480 and a color depth of 65K. The board is intended for embedded projects requiring a local graphical user interface and does not require cooperation with Raspberry Pi or any other single-board computer.

The applied RP2350 microcontroller offers a dual-core and dual-architecture design, enabling operation with ARM Cortex-M33 cores or Hazard3 RISC-V cores, with a clock frequency of up to 150 MHz. The board integrates Flash memory and PSRAM, a TF card slot, and numerous communication interfaces, allowing it to be used in control systems, HMI interfaces, measurement devices, and electronics prototyping.

The RP2350-Touch-LCD-7 version is equipped with a capacitive touch panel supporting up to 5 touch points, communicating via the I2C bus with interrupt support, enabling direct user interaction with the displayed graphical interface.
