Questions
How big is the Sense debug PCB?
It measures 65 × 40 mm and has 4 copper layers, 0.79 mm thick.
What parts does the Sense debug use?
54 parts, built around the TMP117AIDRVR, 298W107X0004M2T, MBR0530 and B2B-PH-SM4-TB(LF)(SN). 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 Sense debug KiCad files?
From the unsurv/NFC_temp repository on GitHub, at the commit this page was made from: the board is hardware/tools/debug/sense_debug.kicad_pcb and its schematic hardware/nfc_pocket_knife/pocket_knife_sense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sense debug design in my own project?
Its repository states no licence, so its author keeps all rights: ask unsurv before reusing the design.
