Resonare: open-source 120 W LCC-S resonant wireless charger, transmitter and receiver boards (KiCad 10, 4-layer)
P1 tx is an open-source printed circuit board by Deco025, from the Deco025/resonare repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 4-layer board of 82 × 60 mm with 92 parts on 73 nets, routed with 336 tracks and 211 vias.
It is built around the UCC27211D, INA240A2D and BSC070N10NS3G, with the SS110 and SMAJ28A among its other parts. Its parts include 43 capacitors, 20 resistors, 7 ICs, 4 diodes and 4 transistors. It belongs with the STM32 boards of this library.
120 W LCC-S 谐振式无线充电:发射板 + 接收板
Resonare (Latin: “to resound”) is an open-source 120 W wireless charger built on an LCC-S resonant topology. A 24 V transmitter drives a full bridge into an LCC compensation network; the receiver rectifies, steps down with a synchronous buck and charges a supercapacitor bank through an ideal-diode stage. Both boards are 4-layer KiCad 10 designs with complete fabrication outputs.

下单要点:
DRC 里保留了几条已接受的丝印告警:驱动器封装的 1 脚标记压在自举电容焊盘上 0.05–0.14 mm;接线端子外框到达板边。这两种情况板厂都会自动裁掉焊盘上和板外的丝印。

BenjaminMeyerEE/Digital-Synchronous-Buck-Converter
12 V to 6 V, 10 A synchronous buck converter with closed-loop digital control on an STM32G474RET6. Custom 4-layer board in KiCad.

Blaze-Pascal/EKA-PiF-MCU_PSU
2-phase synchronous digitally controlled buck converter (30V in, up to 10A out). Features a 4-layer custom KiCad PCB optimized for EMI.
It measures 82 × 60 mm and has 4 copper layers, 1.6 mm thick.
92 parts, built around the UCC27211D, INA240A2D, BSC070N10NS3G and SS110. 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 Deco025/resonare repository on GitHub, at the commit this page was made from: the board is p1_tx/p1_tx.kicad_pcb and its schematic p1/p1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
