About the PowerMux-TPS2121 PCB

PowerMux-TPS2121 is an open source PCB design by AnotherMike-exe, published on GitHub under the MIT license. It is a 4-layer board measuring 15 × 20 mm, with 13 components from 10 distinct parts.

Other key parts include the TPS2121RUXR. By type, the board carries 7 resistors, 5 capacitors and 1 IC.

From the project

Reusable KiCad 10 PCB layout blocks: module reference boards, design block fragments and host setup docs

Reusable PCB layout blocks for Plum Solutions boards. Nine schematic design blocks exist. Each one gets a matching layout so a host project can drop in the parts, the routing and the copper pours already proven on a reference board.

The fragment lives outside this repository, in the shared library on the Plum volume. See docs/ARCHITECTURE.md.

PoE-PD-Si3402-Class1 is retired. PoE always arrives on an Ethernet cable, so a PoE block with no jack was never a drop-in part.
