PBX-MX
From PROBOTIX :: wiki
The PBX-MX is the worlds first ever, breakout board that can be configured for parallel or USB control. The PBX-MX can be used as an isolated parallel port breakout board for use with software such as LinuxCNC or Mach3. Includes an on-board Arduino compatible microcontroller that can be used for monitoring and diagnostics. By changing a couple of solder jumpers and flashing the Arduino, the board becomes a GRBL compatible USB controller for the open source GRBL G-code interpreter.
The PBX-MX features an on-board switching power supply module that can accept up to 76VDC input and outputs a clean 2A@5VDC power rail.
The PBX-MX has 6 of our PBX-Headers for connecting to motor drivers, as well as an additional 10-pin header for limit/home/e-stop connections.
The PBX-MX also sports a 2-pin JST type connector for connecting a cooling fan. This connector outputs the same voltage as Vin.
