About the PicoQuorum key, proposal C: USB-C receptacle PCB
PicoQuorum key, proposal C: USB-C receptacle is an open source PCB design by jmcpheron, published on GitHub under the MIT license. It is a 2-layer board measuring 16 × 36 mm, with 7 components from 5 distinct parts.
Other key parts include the ATECC608C-SSHDA-B and USBLC6-2SC6. By type, the board carries 2 ICs, 2 capacitors, 2 resistors and 1 connector.
From the project
These are KiCad renders of the ordered board, in the colours ordered: blue mask, white silkscreen and silver lead-free HASL pads. KiCad has no 3D model of the HCTL receptacle, so the connector shown is a GCT USB4105, a 16-pin receptacle of the same size and pad layout. The render
These are KiCad renders of the ordered board, in the colours ordered: blue mask, white silkscreen and silver lead-free HASL pads. KiCad has no 3D model of the HCTL receptacle, so the connector shown is a GCT USB4105, a 16-pin receptacle of the same size and pad layout. The renders come from a scratch copy of the board; the files below are untouched.
3D models for CAD: 3d/key-c-P2.step is the assembled board, and 3d/key-c-P2-board-only.step is the bare board. They import into Onshape as-is. Both come from the same scratch copy, with the same GCT stand-in connector at J1's origin. The origin…
