Skiff is a Roadkit-compatible PCB designed by Trash Man. It is the second PCB he has designed to support the new port scanning method for key matrix press detection. The group buy for Skiff ran in Ocrober 2020 with PCBs selling for $25 each.
¶ Design

| LEDs | 4x RGB Indicators |
| Connection | Integrated USB-C |
| Controller | ATmega32u4 |
The PCB has the same dimensions as previous Roadkit PCBs, including mounting hole pattern and USB port location, to ensure compatibility with Roadkit cases. It also includes four new mounting holes in a square pattern. The board is covered in a green solder mask with white silkscreen. The front of the board features an image of a flat-bottomed skiff boat with oars (from which the board derives its name) on the bottom two thirds. The words "The Skiff PCB" are written in bold font in the top left. No pictures or renders of the back of the board have been shown.
Skiff uses a USB-C port for its connection to the host computer. All switches are oriented in the south-facing position, although there are no through-hole pads for in-switch LEDs for any of the switch locations. There are 4 surface-mount RGB LEDs located between the switches in the two rightmost columns.
Although it is designed for Roadkit compatibility, Skiff does not support all Roadkit layouts. The 2x vertical 2u keys on the right side of the numpad layout have been removed. Presumably this was due to the SMD LEDs between the switches interfering with hole placements for PCB-mount stabilizers.
Due to the south-facing orientation of the switches in Skiff, the two top-center switches may contact the anfhor legs on the USB-C connector. This can cause the switches to tilt outward toward the sides of the case. Unfortunately this can only be rectified through destructive methods such as clipping the anchor legs on the USB connector flush with the PCB or cutting small holes in the bottom of the two affected switches to prevent interference.
¶ Layout
Skiff supports two layouts:
- Macropad - 16x 1u keys in a 4x4 grid
- Numpad - a 2u horizontal key replaces the 2x 1u keys in the bottom left
¶ Revisions
There has only been 1 revision of the Skiff PCB.
