BigBoi is a prototype MiniVan-compatible PCB designed by Trash Man to test big spacebar layouts. It was never sold as part of a group buy and only a handful of PCBs were made.
Drawing inspiration from TransitVan, BigBoi was created to support 9u and 9.75u spacebars as well as a prototype ortholinear layout in a standard MiniVan case. A traditional grid of 1u keys will not fit in a 12.75u-wide MiniVan case, leading to a compromise in the ortholinear layout where the 4 keys in the rightmost column are all 1.75u wide. The big spacebar layouts are designed to use 3D printed spacebars made in HuB profile. There are two sets of holes for PCB-mount 7u stabilizers for the large spacebars. The board uses USB C for connectivity with the port located in the upper-right corner to ensure compatibility with MiniVan cases. All switches on the board are in the south-facing orientation. There are no holes for in-switch LEDs and there no SMD LEDs on the board.

BigBoi supports three layouts that all use 9u or 9.75u spacebars. The non-ortho layouts are based on the MiniVan layout with modified bottom rows. A 7u spacebar can be installed on any of the layouts to create additional WKL layouts not shown below.
There has only been a single revision of the BigBoi PCB that was developed as a prototype. The PCB is covered in a green solder mask with white silkscreen. The front of the board is covered in a wavy design while the back includes the name of the board, revision number, and the text "Designed by Trash Man".
