PCB for the SIMO power supply
SIMO Non inverted Buck Boost is an open-source printed circuit board by MorganTL, from the MorganTL/SIMO_HW repository on GitHub. It is a 2-layer board of 218.4 × 92.7 mm with 114 parts on 87 nets, routed with 425 tracks and 16 vias.
It is built around the PDSE1-S12-S15-S, SI8261BAC-C-IS and IPA083N10N5. Its parts include 31 resistors, 18 connectors, 16 capacitors, 12 transistors and 8 ICs. It belongs with the power boards of this library.
Single inductor multiple output (SIMO) power supply PCB. feedback control is done on an external STM32G474. Firmware can be found here.

The 110 most common of 114 parts.
It measures 218.4 × 92.7 mm and has 2 copper layers, 1.6 mm thick.
114 parts, built around the PDSE1-S12-S15-S, SI8261BAC-C-IS and IPA083N10N5. 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 MorganTL/SIMO_HW repository on GitHub, at the commit this page was made from: the board is SIMO_Non_inverted_Buck_Boost.kicad_pcb and its schematic SIMO_Non_inverted_Buck_Boost.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 MorganTL before reusing the design.
