acha666/RP2040_ToolheadPCB_SB
A Toolhead PCB for VORON StealthBurner based on RP2040
It measures 420 × 30 mm and has 2 copper layers, 1.6 mm thick.
109 parts, built around the BC817 and 1N4148WT. 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 theBrutzler/Lineal repository on GitHub, at the commit this page was made from: the board is Lineal/Lineal.kicad_pcb and its schematic Lineal/Lineal.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 theBrutzler before reusing the design.
