This product is a high-performance, highly integrated microcontroller development board designed independently by Waveshare. Despite its compact form factor, it integrates a 1.46-inch capacitive high-definition IPS screen, RTC, six-axis sensors (three-axis accelerometer and three-axis gyroscope), Micro-SD card slot, and other peripherals, facilitating development and integration into products. Unique dual-core, dual-architecture design, featuring a dual-core ARM Cortex-M33 processor and a dual-core Hazard3 RISC-V processor, both clocked at up to 150MHz, allowing users to flexibly switch between the two architectures. Built-in 520KB SRAM and 16MB on-chip Flash Onboard 1.46-inch LCD screen, 412x412 resolution, 65K color. Supports I2C interface control of capacitive touch, 5-point touch, and interrupt support. Onboard 3.7V MX1.25 lithium battery charging/discharging interface Supports low-power sleep and hibernation modes It can be recognized as a mass storage device via USB for drag-and-drop program downloading. 2 I2C ports, 2 UART ports, 7 12-bit ADCs, and 12 controllable PWM channels.
