Overview
Nape is an open-source printed circuit board by menbou0202, from the menbou0202/Nape repository on GitHub. It is a 2-layer board of 127.9 × 25 mm with 21 parts on 25 nets, routed with 154 tracks and 40 vias.
It is built around the MCP1700T-1802E/TT(MS). Its parts include 9 capacitors, 7 switches, 3 ICs and 1 resistor.

Open Nape.kicad_pro with KiCad 10.
The project includes all symbols and custom footprints it references under
libraries/. The project-local sym-lib-table and fp-lib-table use
${KIPRJMOD}, so no global custom-library setup is required.

The PMW3610 circuit is derived from kumamuk-git/roBa, licensed under GPL-3.0, and modified for Nape.
Fabrication and assembly files
gerber/contains the Gerber and plated/non-plated drill files exported in April 2025 for a previous PCB order. The board outline and drill coordinates match the current KiCad 10 design; KiCad 8 and 10 produce some differently ordered Gerber commands and aperture definitions.pcba/Nape_bom.csvandpcba/Nape_cpl.csvare the BOM and placement data from that order. They are JLCPCB ordering references, not a substitute for checking the current board and parts before a new order.
The BT1 placement and rotation in the CPL were corrected manually for the
assembly order. Do not replace this row with an unreviewed KiCad export.
Check the assembly preview and component orientation before submitting any
new PCBA order.
The LCSC part numbers in the PMW3610 circuit are inherited from roBa and match
the JLCPCB-assembled configuration tested with Nape. Some LCSC part
specifications differ from the nominal values displayed in the schematic. In
particular, the BOM uses C19666 for capacitors with several different
nominal values; verify the actual part specifications and availability before
reordering.

Questions
How big is the Nape PCB?
It measures 127.9 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nape use?
21 parts, built around the MCP1700T-1802E/TT(MS). 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 Nape KiCad files?
From the menbou0202/Nape repository on GitHub, at the commit this page was made from: the board is pcb/Nape.kicad_pcb and its schematic pcb/Nape.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nape design in my own project?
Its repository states no licence, so its author keeps all rights: ask menbou0202 before reusing the design.
