It works much like a Raspberry Pi Pico, with the addition of W5500-based wired Ethernet.The board pinout is directly connected to the RP2040 GPIO and follows the Raspberry Pi Pico board pinout. Note that GPIO17, GPIO20, GPIO21, GPIO22, GPIO23, GPIO24, and GPIO25 are not available due to internal board connections.USB-C is provided for power, data and reprogramming the flash, with a built-in RJ45 connector and 3-pin ARM Serial Wire Debug port for development and debugging. Documentation includes the W55RP20 Datasheet and RP2040 Datasheet.Features:Microcontroller: W55RP20 microcontrollerFlash execution: External Quad-SPI Flash with eXecute In Place (XIP)Bus fabric: High performance full-crossbar bus fabricDigital peripherals: Various digital peripheralsProgrammable IO: Flexible, user-programmable high-speed IOInterface emulation: Can emulate interfaces such as SD Card and VGAInternet protocols: Supports Hardwired Internet Protocols: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoEHardware sockets: Supports 8 Independent Hardware SOCKETs simultaneouslySPI: Supports High Speed Serial Peripheral Interface(SPI MODE 0, 3)USB: USB C port for power and data (and for reprogramming the Flash)Ethernet PHY: 10 / 100 Ethernet PHY embeddedAuto negotiation: Supports Auto NegotiationDuplex: Full / Half DuplexEthernet: 10 / 100 BasedRJ45: Built-in RJ45 (POE)Power conversion: Built-in DCDC (PWM/PFM)POE: Additional modules are installed to enable POESpecifications:Flash: Internal 2MByte FlashProcessor: Dual-core cortex M0+ at up to 133MHzSRAM: 264kByte multi-bank high performance SRAMGeneral Purpose IO: 22 multi-function General Purpose IO (4 can be used for ADC)IO Voltage: 1.8-3.3V IO Voltage (NOTE.
