PCB Prototype Test Board
Budget: $10 – $30 USD
I have a circuit idea that now needs to move from the sketchpad to a real-world prototype. The end goal is a fully built, ready-to-power-up PCB that I can use purely for test and evaluation.
It is a basic esp32 temperature humidity detector with OLED. This is only to make a working prototype to test.
I’m flexible on the technical route you take. Whether the design ends up single-, double- or multi-layer is entirely your call once you’ve balanced trace density, signal integrity and overall cost. The same freedom applies to board size, component selection and any IPC standards you feel are appropriate. What matters most is that the finished board functions reliably for bench testing and arrives with all the data.
The project should be created with EasyEDA
Deliverables I’ll need:
• Schematic and layout files (Altium, KiCad or similar) - ready to upload to pcb maker
• Complete Gerbers and drill files ready for fabrication
• A concise BOM with part numbers and sourcing notes
The text name/logo should be on the pcb - "sugar"
You can check the component list and modify if needed
