A detailed comparison reveals significant quality issues with an AliExpress Raspberry Pi Pico 2 clone board. The clone features improper USB trace impedance (130Ω), a cut ground plane affecting signal integrity, incorrect buck converter routing with an unconnected VREG_FB pin, and an underpowered DC-DC converter (800mA vs 1A) that failed during load testing. Despite offering a USB-C connector instead of micro-USB, the clone's poor design choices make it unreliable for serious use.
