Project description
Project Overview This build turns the WIZnet W5500-EVB-Pico into a rock-solid, four-universe Art-Net node for pixel-dense LED sculptures. Hardware TCP/IP off-load in the W5500 guarantees stable UDP throughput while the RP2040’s PIO + DMA stream 800 kHz LED data, achieving ~120 FPS for 680 pixels. The 5-24 V tolerant buck and IP-rated connectors make it ready for touring installations. Key Features Hard-wired Ethernet – W5500 handles MAC/PHY, freeing CPU time for LED timing. 4 independent outputs – each drives up to 170 pixels (one DMX universe) in parallel. High refresh – ~120 FPS at full…
