Overview
Xiao LIF is an open-source printed circuit board by YYK2007, from the YYK2007/software-lif-input-device repository on GitHub. It is a 2-layer board of 97.8 × 75.4 mm with 16 parts on 34 nets, routed with 139 tracks and 0 vias.
Its parts include 6 resistors, 6 diodes, 1 connector and 1 switch. It belongs with the ESP32 boards of this library.
README
README.mdSoftware LIF Input Device
Software LIF Input Device is a XIAO-based input-device experiment that models leaky-integrate-and-fire behavior in software while testing custom board files, firmware, and visualizers.
Project
This project sits between the analog neuron-board work and the later wearable signal-processing work. Instead of implementing every neuron behavior physically, it uses software to model the LIF loop and turns that behavior into an input-device experiment.
The repository includes KiCad files, firmware, visualizers, and development notes for the XIAO-based board. The point was to test how a neuron-inspired signal could be read, displayed, and used as an interface element with a board I could fabricate and program myself.

Questions
How big is the Xiao LIF PCB?
It measures 97.8 × 75.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Xiao LIF use?
16 parts. 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 Xiao LIF KiCad files?
From the YYK2007/software-lif-input-device repository on GitHub, at the commit this page was made from: the board is source/Xiao_LIF.kicad_pcb and its schematic source/Xiao_LIF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xiao LIF design in my own project?
Its repository states no licence, so its author keeps all rights: ask YYK2007 before reusing the design.
