README
README.md6 Axis Breakout
This is a breakout board designed to expand the V2 Smoothieboard in order to use up to 6 axis. It gives the breakouts for step/dir/en along with endstops for the axes and connections which are not on the mainboard. It uses 4 of the Gadgeteer headers to add these functions:
-Step/Dir/En for all 6 axes (bidirectional level shifted)
-Endstop min/max for ABC axes (buffered and identical to the XYZ Endstops on the mainboard)
-4 small FETs (2n7002) which are connected to HWPWM so they can be used for things like hobby servos, BLtouch, small devices, etc.
-UART0 breakout (bidirectional level shifted)
-EStop input (bidirectional level shifted)
-Vfet in for supplying a voltage other than 5v to run things like hobby servos. (Jumper selected and disabled by default. 5v default voltage to header)
-Header to breakout all functions to a daughterboard or large single harness. (i.e. Parallel port connector board for retrofitting existing machines)

Questions
How big is the 6-Axis Breakout PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 6-Axis Breakout use?
103 parts, built around the 74LCX07T, TPD4E1U06DCKR and BSS138PS. 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 6-Axis Breakout KiCad files?
From the Ccecil/6-Axis-Breakout repository on GitHub, at the commit this page was made from: the board is 6AxisBreakout/6AxisBreakout.kicad_pcb and its schematic 6AxisBreakout/6AxisBreakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6-Axis Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ccecil before reusing the design.
