In stockThe Story
The USR-ES1 is a compact Ethernet module featuring the W5500 chip, which implements the TCP/IP protocol stack in hardware. With an SPI interface and 3.3V TTL levels, it offloads network processing from the host MCU, improving system efficiency and reliability. Ideal for embedded systems requiring high-speed Ethernet connectivity, this module includes 32KB of on-chip RAM for data buffering and is compatible with WIZ820io pinout.
