W5500-EVB-Pico

The W5500-EVB-Pico is a microcontroller evaluation board that merges the features of the Raspberry Pi RP2040 microcontroller with the W5500 fully hardwired TCP/IP controller. This integration offers the standard functionalities of a Raspberry Pi Pico board, with the added advantage of Ethernet capabilities through the W5500 component. The board is compatible with IoT platforms such as AWS IoT Core and is Microsoft Azure Device Certified. Key specifications of the W5500-EVB-Pico include: 1. It is equipped with an RP2040 microcontroller featuring 2MByte Flash, a dual-core Cortex M0+ that can run up to 133MHz, and 264kByte multi-bank high-performance SRAM. The RP2040 also supports external Quad-SPI Flash with execute-in-place (XIP) capability and has a high-performance full-crossbar bus fabric. 2. The board boasts 30 multi-function General Purpose IO pins, of which 4 can be used for ADC, with an IO voltage ranging from 1.8-3.3V. It includes a 12-bit 500ksps Analogue to Digital Converter (ADC) and various digital peripherals such as 2 UARTs, 2 I2C, 2 SPI, 16 PWM channels, a timer with 4 alarms, and a Real-Time Counter. There are also 2 Programmable IO (PIO) blocks totaling 8 state machines, offering flexible, user-programmable high-speed IO that can emulate interfaces like SD Card and VGA. 3. The W5500 module embedded in the board supports hardwired Internet protocols such as TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE. It can handle 8 independent hardware sockets simultaneously and includes an internal 32 Kbytes memory for TX/RX buffers. The W5500 supports high-speed Serial Peripheral Interface (SPI MODE 0, 3). 4. The board includes a Micro-USB B port for power, data transfer, and reprogramming the Flash. It has a 40-pin 21x51 'DIP' style 1mm thick PCB with 0.1" through-hole pins along with edge castellations. A 3-pin ARM Serial Wire Debug (SWD) port is also present. - **Networking Capabilities**: It features a 10 / 100 Ethernet PHY, supports auto-negotiation (full/half duplex, 10/100 based), and includes a built-in RJ45 connector. 5. The pinout of the W5500-EVB-Pico is directly connected to the GPIO of the RP2040, mirroring the Raspberry Pi Pico board. Specific GPIO pins (16, 17, 18, 19, 20, 21) are connected to the W5500 inside the board for SPI communication to enable Ethernet function. Additional pins on the main 40-pin interface include VBUS, VSYS, 3V3_EN, 3V3, ADC_VREF, AGND, and RUN. 6. The board can operate within a temperature range of -20°C to 85°C. However, it's recommended to maintain a maximum ambient temperature of 70°C for optimal performance. The VBUS requires a DC 5V (± 10%) power supply, while the VSYS can vary between 4.3V to 5.5V. Overall, the W5500-EVB-Pico is a versatile and powerful development board suitable for a variety of applications, especially those requiring Ethernet connectivity combined with the flexibility and performance of the Raspberry Pi RP2040 microcontroller.
