Pavel Kováč, SOS electronic product specialist, has summarized the most important information, including the main reasons why you should definitely not overlook this product.

5 reasons to reach for the W5100S-EVB-Pico:

  • Ready2use solution for IoT applications.
  • It contains Raspberry Pi RP2040 microcontroller. 
  • Excellent quality/price ratio. 
  • The basis is the W5100 chip for connection to the Ethernet network.
  • Low consumption.

The 133MHz RP2040 MCU has a dual ARM® Cortex®-M0 + core providing high performance also with using various low-power modes to support operation from battery power. The RP2040 is also equipped with 2MB Flash memory on a chip, a symmetric dual-core processor, a deterministic bus fabric and a rich set of peripherals, enhanced by an RPi programmable I/O subsystem.

The W5100S-EVB-Pico development kit from WIZnet can work in the same way as the Raspberry Pi Pico and it additionally includes the W5100S TCP/IP chip. It supports Ethernet cable connection via Media Access Control (MAC), 10Base-T / 100Base-TX Ethernet PHY and is a single-chip solution for the TCP/IP Internet protocol.

It provides an easy way to extend the Internet connection for efficient and small embedded systems with the help of the RP2040 MCU and W5100S TCP/IP controller.
