OddPCIe
About the OddPCIe PCB
OddPCIe is an open source PCB design by a-little-wifi, published on GitHub. It is a 4-layer board measuring 30.5 × 45.5 mm, with 15 components from 8 distinct parts.
Other key parts include the AP1117-33. By type, the board carries 7 capacitors, 3 connectors, 2 diodes, 2 resistors and 1 IC.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
PCIe breakout for Dell Latitude laptop optical drive modular bay
The optical drive (odd) SATA ports on a number of Dell Latitude laptops from 2011-2013 have a PCIe x1 lane hidden in them, meant for use with the AE3USB01 (DP/N P5MKF) USB 3.0 expansion module:
Note: The E6440, E6540 and M2800 don't seem to support hot-plug on this PCIe port, as they never actually shipped with anything using this port (the AE3USB01's bezel doesn't even line up with the case)
