W5100S-EVB-Pico Evaluation Board WIZnet W5100S-EVB-Pico Evaluation Board is a compact development platform based on the Raspberry Pi RP2040 Microcontroller. The 133MHz RP2040 MCU has a dual Arm® Cortex®-M0+ core delivering high performance, with a variety of low-power modes to support extended-duration operation on battery power. The RP2040 also features a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and a rich peripheral set augmented with the RPi Programmable I/O (PIO) subsystem.
