Wiznet makers

Test Setup

• Hardware: RP2350 SM board + custom W6300 board
• Tool: iperf
• Reference Blog: Engineer's LAB – RP2350 SM board W6300 TCP Throughput Test
• Example Code: GitHub – WIZnet-PICO-IPERF3-C / examples / iperf3 / toe

How the Test Works

• Run the board

Build and upload the example firmware to RP2350 + W6300.

The board runs in iperf server mode.

• Run iperf client on PC

iperf3 -c [Board_IP] -t 60 -i 1

-c [Board_IP]: connect to the board (server)

-t 60: run the test for 60 seconds

-i 1: print results every 1 second

• Check the results

Throughput results are displayed on the PC console.

Why This Matters

• Real reference data

Provides one of the  public performance measurements for W6300.

• Easy to reproduce

Anyone with the hardware can repeat the same test using iperf3.

• Optimization insights

Shows how performance varies with different test conditions, useful for real-world tuning.
