mtthewwatts/12V5VBuckConverter
12V to 5V buck converter using LM2679, designed in KiCad 9. This was made for my MTE380 Course Project, to specifically fit my robot, but the physical board can be altered to fit other designs.

Electrical schematic and layout for capstone design project.
FYDP is an open-source printed circuit board by Michael-Done, from the Michael-Done/FYDP_ELEC repository on GitHub. It is a 2-layer board of 65 × 56 mm with 43 parts on 70 nets, routed with 238 tracks and 98 vias.
It is built around the ATTINY88-AU, DRV8251ADDA and VS-6TQ045S-M3. Its parts include 11 capacitors, 11 resistors, 5 connectors, 4 diodes and 3 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.

43 parts, built around the ATTINY88-AU, DRV8251ADDA and VS-6TQ045S-M3. 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 Michael-Done/FYDP_ELEC repository on GitHub, at the commit this page was made from: the board is FYDP/FYDP.kicad_pcb and its schematic FYDP/FYDP.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 Michael-Done before reusing the design.
