Questions
How big is the NodeHardware PCB?
It measures 80 × 106 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NodeHardware use?
220 parts, built around the CH340C, ESP32-S3-WROOM-1-N8, SPX3819M5-L-3-3 and BAT54S. 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 NodeHardware KiCad files?
From the AleksaHeler/FlexNode repository on GitHub, at the commit this page was made from: the board is Node/NodeHardware/NodeHardware.kicad_pcb and its schematic Node/NodeHardware/MCU_And_Peripherals.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NodeHardware design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
