Breakout board for the V2 Smoothieboard which allows expansion to 6 axis. Also has a header intended to add a secondary breakout for retrofitting parallel port driven machines
6-Axis Breakout is an open-source printed circuit board by Ccecil, from the Ccecil/6-Axis-Breakout repository on GitHub. It is a 4-layer board of 80 × 80 mm with 103 parts on 90 nets, routed with 1,002 tracks and 148 vias.
It is built around the 74LCX07T, TPD4E1U06DCKR and BSS138PS. Its parts include 24 connectors, 22 resistors, 13 transistors, 8 capacitors and 3 ICs. It belongs with the interfaces and adapters and microcontroller boards boards of this library.
6 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)
