RP2350-Touch-LCD-2.8
Integrates SPI interface display, 240×320 pixels, multiple peripheral interfaces
Features
RP2350-Touch-LCD-2.8 is a low-cost, high-performance MCU board designed by Waveshare. It features an onboard 2.8-inch capacitive touch display capable of smoothly running GUI programs such as LVGL. The board integrates a lithium battery recharge manager, a 6-axis sensor (3-axis accelerometer and 3-axis gyroscope), an RTC chip, and more, making it easy to develop and integrate into products quickly.
Key features include:- RP2350 microcontroller chip designed by Raspberry Pi in the United Kingdom
- Dual-core and dual-architecture design: dual-core ARM Cortex-M33 processor and dual-core Hazard3 RISC-V processor, flexible clock running up to 150 MHz
- 520KB of SRAM and 16MB onboard Flash memory
- Onboard 2.8-inch LCD display, 240×320 resolution, 262K color
- Supports capacitive touch function controlled via I2C interface, 5-point touch, with interrupt support
- Adapts UART, I2C, and some IO interfaces; integrates a full-speed USB port
- Onboard speaker, QMI8658 6-axis sensor, RTC sensor, TF card slot, and battery recharge management module
- Drag-and-drop programming using mass storage over USB
- Supports accurate control such as flexible clock and multiple power modes to realize low power consumption in different scenarios
