Omnibus is a MiniVan-compatible PCB designed by Aeternus.
The first group buy for Omnibus PCBs ran in August 2021 for $40. Omnibus PCBs were available as addon items for the first Carpool and Pomelo group buys.

Omnibus is a drop-in replacement PCB for MiniVan cases that supports nearly every MiniVan bottom row layout ever created. It has an extensive list of features including:
- 25+ unique bottom row layouts
- Support for all tray mount Minivan cases
- Support for most top and bottom mount cases
- RGB underglow with 22 LEDs
- Optional split 1u backspace + rotary encoder in place of a 1.75u backspace key
- USB Type-C connector
- Snap-off USB connector and rear-mount JST connector for cases that use a USB daughterboard
- Snap-off PCB mount tabs for Trolley case support (remove for installation in MiniVan cases)
- QMK support
- Vial support for on-the-fly keymap configuration
PCB-mount stabilizers are supported for all spacebar positions, though some mounting points may interfere with the "gummy worm" mount for Trolley cases (an upcoming case for Omnibus created by Aeternus). There are no holes for user-installed per-key or RGB LEDs anywhere on the board. The board uses a USB-C connector to connect to the host. The port is located in the top-right to ensure compatibility with MiniVan cases. Tray-mount holes and the reset switch are positioned to maintain compatibility with tray-mount MiniVan cases.
Only the left JST connector supports USB connectivity.
Do not plug in cables to the USB port and a USB daughterboard at the same time.
The PCB includes pads for two JST headers. The first header located near the USB port supports connecting to a USB-C Unified Daughterboard for cases like Pomelo and MB-44. The second header is located in the middle of the PCB and supports an addressable RGB LED strip. A pair of pads located under the RGB header must be bridged with solder to enable the RGB underglow LEDs if an RGB strip is not installed.
¶ Layout
Omnibus supports a staggering number of layouts and it would be unrealstic to break them all down here. I'm not even going to include a screenshot of the KLE you should just go look at it yourself.
Omnibus uses standard stagger for the top 3 rows. Nearly all of the layout customizability comes from the multitude of bottom row options. In short, Omnibus supports:
- All MiniVan layouts (including JISVan)
- All Ketch layouts
- JetVan layout
- Minisub split space
- m3n3van r2 layout (only top-right encoder is supported by Omnibus)
- All MB44 layouts (minus bottom-left encoder)
- Many more unique layouts not listed here
¶ Revisions
¶ Rev 2.0
A handful of r2 boards were produced to confirm fit and functionality with MiniVan cases. They are green with white silk screen artwork. R2 PCBs do not support all bottom row layouts and mounting options. It is unlikely these will ever be found in the wild.
¶ Rev 3.0
R3 PCBs were only seen in renders. There were issues with stabilizer cutout placements for some layouts.
¶ Rev 4.0
R4 PCBs were available during two dedicated group buys as well as the Pomelo case group buy. The boards are green with white silk screen artwork. This revision supports all layouts shown in the KLE linked above.
