The **RP2350-MINI(ETH)** development board is developed using the Raspberry Pi dual-core dual-architecture microcontroller **RP2350A** and the **W5500** Ethernet control chip. With a pin header design, it also has an extremely small PCB area, making it very convenient for users to directly weld and integrate it onto the self-designed baseboard. Meanwhile, they can also weld the pins with a pitch of 2.54mm and directly insert them onto the self-designed baseboard. The board also exposes a **Type C port, RGB LEDs**, a **reset button**, a **BOOT button**, and an **RJ45 connector**, which is convenient for users to develop and debug. This development board is highly suitable for maker projects, building automation control systems, small network devices, embedded system development, and DIY electronic products

### **Product Features**

- **Dual-core Microcontroller**: Powered by the **RP2350A Raspberry Pi dual-core microcontroller**, featuring either dual-core **Arm Cortex-M33** or dual-core **Hazard3 RISC-V processor** running at **150MHz**.

- **The W5500 **chip supports** hardware TCP/IP protocols: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE.**

- **The W5500 **has an internal **32KB buffer **and supports up to** 8 independent sockets **for simultaneous communication.

- **The W5500** supports auto-negotiation (**10/100-Based full-duplex/half-duplex**).

- **USB Type-C Port**: Supports **USB 1.1 host and device**, enabling drag-and-drop file downloads to large-capacity storage.

- **Onboard Buttons and LEDs**: Includes **RUN reset button**, **BOOT button**, and **RGB LED WS2812**,**RJ45 connector**.

- **Rich Open-Source Resources**: Supports **C/C++** and **MicroPython**, with extensive documentation and example resources available for development.
