A custom PCB breadboard was designed for controlling multiple DC pumps in a liquid transfer project, featuring a dedicated SOIC-8 footprint for an AO4406 MOSFET and various protective components. The layout allows for manual connections similar to traditional breadboards, and the design was finalized and produced by NextPCB within a week. The author emphasizes the advantages of using HQDFM software for design verification and notes NextPCB's initiative to support innovative projects through free assembled RP2040-based PCBs.
