Product Features
This product is a low-cost, high-performance microcontroller development board designed by Waveshare. It has a 2.8-inch LCD screen, a lithium battery charging chip, a six-axis sensor (three-axis accelerometer and three-axis gyroscope), RTC and other peripherals on board, which is convenient for development and embedding into products. It can run GUI interface programs such as LVGL smoothly.
The main features are:
- RP2350 microcontroller chip designed with Raspberry Pi
- Unique dual-core, dual-architecture, equipped with a dual-core ARM Cortex-M33 processor and a dual-core Hazard3 RISC-V processor, running at clock frequencies up to 150MHz
- Built-in 520KB SRAM and 16MB on-chip Flash
- Onboard 2.8-inch LCD screen, 240 × 320 resolution, 262K colors
- Support I2C interface to control capacitive touch, 5-point touch, support interrupt
- Lead out UART, I2C and some IO interfaces, integrate full-speed USB serial port
- Onboard speakers, QMI8658 six-axis sensor, RTC clock sensor, Micro SD card holder and battery charging management module, etc.
- USB can be recognized as mass storage for drag-and-drop program downloading
- Supports flexible clock, multiple power modes and other accurate control to achieve multi-scenario low power consumption mode
