README
pcb_design/Piezo_Demo_7x7/README.mdPiezo Demo 7x7
- KiCad 9 schematic and fully routed two-layer PCB.
- 224 mm x 224 mm board with a 7 x 7 grid of 32 mm cells.
- 43 buzzer footprints, two rows of seven MouseMinder SMD selector buttons, a vertical BNC input, and a reserved switching/MCU cell.
- Available EasyEDA 3D bodies are included and linked project-relatively.
- The BNC includes a simplified project-local preview body based on the TE product envelope.
- Front silkscreen: cell and MPN.
- Back silkscreen: MPN, LCSC number, live LCSC 1-piece/500-piece unit pricing, voltage, current, SPL, driver type, mount, and body size.
Five unavailable EasyEDA records use same-family fallback geometry. Verify every footprint against the purchased part's current datasheet before fabrication.
The schematic directly connects the BNC through one selected row switch and one selected column switch. Press one button from each bank to connect the corresponding buzzer. G2-G7 are unused.
ERC and PCB DRC both pass with zero violations and zero unconnected pads. JLCPCB-ready Gerbers are in fabrication/Piezo_Demo_7x7_JLCPCB_Gerbers.zip.

Questions
How big is the Piezo Demo 7x7 PCB?
It measures 224 × 224 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Piezo Demo 7x7 use?
58 parts, built around the LCK-TA022H18-2WL, CPT-9019A-SMT-TR, FSR-1407TP-5V and FSR-1707TP-5V. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Piezo Demo 7x7 KiCad files?
From the Radacon/MouseMinder repository on GitHub, at the commit this page was made from: the board is pcb_design/Piezo_Demo_7x7/Piezo_Demo_7x7.kicad_pcb and its schematic pcb_design/MouseMinder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Piezo Demo 7x7 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Radacon before reusing the design.
