Morse mesh v2 is an open-source printed circuit board by eihli, from the eihli/morse-mesh repository on GitHub. It is a 2-layer board of 229.7 × 135.6 mm with 75 parts on 67 nets, routed with 455 tracks and 179 vias.
It is built around the TPS63802DLAR, BQ24074RGTR and TPS22917DBV, with the CL21A106KAYNNNE, CL21A475KAQNNNE and CL21B104KBCNNNC among its other parts. Its parts include 24 resistors, 11 capacitors, 9 connectors, 6 diodes and 4 ICs.
This is the current hardware source for future Morse Mesh revisions. It is a
professionally reviewed redraw of the frozen, fabricated v1 board, not a
pin-compatible replacement: notably, KEY_IN moved from v1 PA0 to v2 PC1.

Serra-Rocketry/ignitor
[Propulsion] Remote ignition system for rocket motors.
It measures 229.7 × 135.6 mm and has 2 copper layers, 1.6 mm thick.
75 parts, built around the TPS63802DLAR, BQ24074RGTR, TPS22917DBV and CL21A106KAYNNNE. 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.
From the eihli/morse-mesh repository on GitHub, at the commit this page was made from: the board is hardware/kicad/morse-mesh-v2/morse-mesh-v2.kicad_pcb and its schematic hardware/kicad/morse-mesh-v2/morse-mesh-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask eihli before reusing the design.
