40700 (pronounced "forty-kay-seven-hundred") is a 14u-wide 40% keyboard that supports full-size modifiers.
A handful of prototype boards were produced in mid-2019 with 3D printed cases and white FR4 plates.
A new group buy was organized in April 2021 for a small run of 10 boards.
40700 is a revised version of TtocyobItna that adds a centered 7u spacebar and a modified bottom row layout to remove the corner blockers on the case. A symmetrical 1.25/1/1.25 modifier layout flanks both sides of the spacebar. The case uses a gasket mount to secure the switch plate.

The prototype 40700 PCB supports a single, fixed layout as described above.

The new PCB produced for the group buy adds several new switch positions. The 1.5 and 1u keys in the top-right corner can now be swapped. An extra footprint was added for a stepped Caps Lock key. Additionally, a rotary encoder can be installed in the 1u position in the very top-right corner.
Both PCB revisions have all switches oriented in the south-facing position. PCB-mount stabilizer holes are included for the three stabilized keys (left Shift, Enter, Spacebar) on both boards. There are no per-key through-hole or surface mount LED locations and no pads for indicator LEDs.
The board is covered in a red solder mask with no notable silkscreen details on either side. A reset switch is located on the underside of the board under the Backspace switch position.
A new PCB was produced for the group buy. It is white with black silkscreen. Several new switch positions were added for stepped Caps Lock and swapping the 1.5/1u keys in the top right corner. The 1u position in the very top-right supports a rotary encoder.
The front of the board includes the text "40700 by the mother f****** trash man".
A 3D printed case was designed to fit the PCB but the files to print the case have not been not made publicly available. White FR4 plates were produced alongside the PCBs. Examples of the case can be seen above.
The Round 1 case is a two-piece, gasket mount design made of milled acrylic. Cases included either brass or carbon fiber switch plates.
