README
README.mdKapton Heater System for Oxidizer Tank Pressure Regulation
This system uses a 24V, 14.6A Kapton trace heater to regulate the pressure inside a nitrous oxide oxidizer tank, particularly in colder environments where vapor pressure drops below optimal levels. The heater is PWM-controlled via a high-current N-channel MOSFET, allowing for precise thermal regulation.

Questions
How big is the KAPTON HEATERV2 PCB?
It measures 90 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KAPTON HEATERV2 use?
33 parts, built around the TC4427ACOA, XT60PW-M, 10090926-P154XLF and AO3400A. 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 KAPTON HEATERV2 KiCad files?
From the AslanLauzon/KAPTON-CONNECTOR repository on GitHub, at the commit this page was made from: the board is KAPTON-HEATERV2.kicad_pcb and its schematic KAPTON-HEATERV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KAPTON HEATERV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask AslanLauzon before reusing the design.
