From the project
Handheld C-Line Hub Disinfection Device to Avoid CLABSI (Central Line Associated Bloodstream Infection)
Handheld C-Line Hub Disinfection Device to Prevent CLABSIs (Central Line Associated Bloodstream Infections)
CLABSI is a handheld medical device that disinfects central-line (C-line) hubs using UVC light. The device uses hardware interlocks to ensure safe operation and provides audible and visual feedback throughout the disinfection cycle.
Fab-ready Gerber zips are in KiCad/Exports/.

XIAO nRF54l15: common questions
What microcontroller does the XIAO nRF54l15 use?
The XIAO nRF54l15 is built around the nRF54L15-CAAA-R, from the Nordic nRF family.
How big is the XIAO nRF54l15 PCB?
The XIAO nRF54l15 measures 21 × 17.8 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the XIAO nRF54l15?
101 components, from 52 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the XIAO nRF54l15 design files?
From the Nick-Trigger/CLABSI repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the XIAO nRF54l15 design in my own project?
The repository has no license, so all rights stay with Nick-Trigger. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the XIAO nRF54l15 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
