Overview
Skis is an open-source printed circuit board by kraakenstuff, from the kraakenstuff/Skis repository on GitHub. It is a 2-layer board of 29.2 × 109.2 mm with 96 parts on 76 nets, routed with 866 tracks and 115 vias.
It is built around the LM13700M, BS170FTA and MMBT3904, with the MMBT3906 among its other parts. Its parts include 38 resistors, 18 capacitors, 11 connectors, 10 transistors and 4 diodes.

README
README.mdSkis
This is smd version of Bastl Skis v1. Main differences are:
- It has skis (two sliders) vs. no skis in Bastl version
- 6HP vs. 5HP, for obvious, OCD reasons
- Range switch vs. range backside jumper (although this switch works as a jumper - instead of going from freq0 to freq1, and then from freq1 to freq2 in the second position, it goes from freq0 to freq1, and then from freq0 to freq2)
- Version 2 of Bastl Skis has decay CV input, and this one doesn't have it
- Version 1 of Bastl Skis was THT and had two sandwiched boards, and this one is SMT in one board.
Status: tested and working.

Questions
How big is the Skis PCB?
It measures 29.2 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Skis use?
96 parts, built around the LM13700M, BS170FTA, MMBT3904 and MMBT3906. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Skis KiCad files?
From the kraakenstuff/Skis repository on GitHub, at the commit this page was made from: the board is Skis.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skis design in my own project?
Its repository states no licence, so its author keeps all rights: ask kraakenstuff before reusing the design.
