1. This product is a high-performance, highly integrated microcontroller development board independently designed by Waveshare. Within its compact form factor, it integrates peripherals including a 3.5-inch capacitive HD IPS display, highly integrated power management IC, low-power audio codec, camera interface, 6-axis IMU (3-axis accelerometer + 3-axis gyroscope), RTC, and Micro SD card slot, facilitating development and product integration.
2. Features Raspberry Pi-designed RP2350B microcontroller chip
3. Unique dual-core/dual-architecture: Dual ARM Cortex-M33 cores + dual Hazard3 RISC-V cores, both operating at up to 150MHz, enabling flexible architecture switching
4. Built-in 520KB SRAM and 16MB on-chip Flash
5. Type-C interface eliminates orientation concerns
6. Onboard 3.5-inch capacitive touch HD IPS screen with 320 × 480 resolution and 65K colors for clear image display
7. Integrated ST7796 display driver and FT6336 capacitive touch controller using SPI and I2C interfaces respectively, minimizing pin consumption
8. Camera interface compatible with mainstream modules (e.g., OV2640, OV5640) for image/video capture
9. Onboard 3.7V MX1.25 lithium battery charge/discharge interface
10. USB 1.1 host/device support
11. Low-power sleep/hibernation modes
12. Programmable via drag-and-drop when recognized as USB mass storage
13. 22 multifunctional GPIO pins: 2×SPI, 2×I2C, 2×UART, 7×12-bit ADC, 18×PWM channels
14. Precision on-chip clock/timer modules
15. Built-in temperature sensor for real-time chip monitoring
16. 12 programmable I/O (PIO) state machines for custom peripheral support
