This board is a combination of the PWM Driver Board, DC Motor Driver Board, Temperature Sensor Board, RS485 comms, and an Arduino! All on one board. It has screw terminals for easy hookup, as well as a power jack for power and an IDC header for the rotary encoder. Its an all-in-one solution for controlling an extruder.

Some highlights:

* Onboard atmega168 - program it just like an Arduino because it is an Arduino.
* 3 x MOSFET drivers for controlling up to 14A @ 12V. Perfect for heaters, fans, solenoids, etc.
* 2 x H-Bridges capable of up to 2A each. Control 2 motors, or control one stepper motor.
* A temperature sensor circuit for reading the standard 100K thermistor.
* RS485 connection for noise-free communications with the motherboard.
* IDC header for connecting a Magnetic Rotary Encoder.
* Polarized ICSP header for simple, easy programming.
* It mounts directly to the Pinch Wheel Extruder!
* It is plug and play with the RepRap Motherboard.

In the POV's archives you include two libaries: tools.inc an user.inc that they aren't included in the download. How can i get them?


So, why are the schematics and pcb only in the format for a proprietary software package? Both gEDA and KiCad are fully open source and more capable than the crippled free-Eagle. And unless I missed it, there isn't even a postscript file for the schematics? grump
