Four 25 F cells in series for CANary-PWR's LTC3350 hold-up, on a lead (design record: docs/CANary-PWR-Spec.md §P4). The board has no active parts: four cells, an NTC, two Kelvin net ties and a Micro-Fit 2 × 5 header.

Leviathan Main Controller for Voron 2 / Trident 3D Printers
Leviathan V1.3 is an open-source printed circuit board by MotorDynamicsLab, from the MotorDynamicsLab/Leviathan repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 170 × 100 mm with 420 parts on 349 nets, routed with 2,501 tracks and 571 vias.
It is built around the 74LVC1G17GW, TMC2209-LA-T and MCP1416-E/OT, with the SIZ270DT, BAT54J,115-JSM and DSK14 among its other parts. Its parts include 168 capacitors, 111 resistors, 24 diodes, 16 transistors and 11 ICs.

Voron Leviathan is collaboration between JNP and the team at LDO to create a controller board specific for the needs of Voron 3D printers. It features:

The 377 most common of 420 parts.
It measures 170 × 100 mm and has 4 copper layers, 1.6 mm thick.
420 parts, built around the 74LVC1G17GW, TMC2209-LA-T, MCP1416-E/OT and SIZ270DT. 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 MotorDynamicsLab/Leviathan repository on GitHub, at the commit this page was made from: the board is KiCad/V1.3/Leviathan_V1.3.kicad_pcb and its schematic KiCad/V1.2/Leviathan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
