The Colorado TK1 SOM is a small form factor board similar to the Jetson TK1. The main differences lie in the pinmux, and in that the PCIe controller is set to use in 4lanes+1lane, rather than 2+2. The pinmux header here was generated from a spreadsheet provided by Colorado Engineering using the tegra-pinmux scripts. The spreadsheet was converted from v09 to v11 by me.
