mikesmitty/power-manifold3Six-port USB-C power supply: up to 100 W per port from one 24 V supply, with per-port control, priority-based power sharing and Home Assistant support. 100% local, no cloud required.
Controller is an open-source printed circuit board by mikesmitty, from the mikesmitty/power-manifold repository on GitHub, published under the MIT licence. It is a 4-layer board of 101.2 × 28 mm with 103 parts on 107 nets, routed with 720 tracks and 178 vias.
It is built around the RP2350A, W25Q128JVSIQ and W6100 (L/Q), with the AP7361C-33E, BM03B-SRSS-TB(LF)(SN) and X322525MRB4SI among its other parts. Its parts include 40 capacitors, 35 resistors, 11 connectors, 5 ICs and 3 switches. It belongs with the power and home automation and IoT boards and the RP2350 boards of this library.
A six-port USB-C® power supply: USB Power Delivery 3.2, up to 100 W per port from one 24 V supply, with per-port control, priority-based power sharing and Home Assistant support. This repository holds the hardware (KiCad), the firmware and the documentation site.

It measures 101.2 × 28 mm and has 4 copper layers, 1.61 mm thick.
103 parts, built around the RP2350A, W25Q128JVSIQ, W6100 (L/Q) and AP7361C-33E. 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 mikesmitty/power-manifold repository on GitHub, at the commit this page was made from: the board is hardware/controller/controller.kicad_pcb and its schematic hardware/backplane-backer/backplane-backer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
