PCB ready for first Prototype of Smoothieboard v2 Pro.

Looks amazing!
How much more expensive will the final assembled board be compared to smoothie1 in a similar configuration (without the edison)?
@David_Piwczyk This is the Smoothie 2 pro. The smoothie 2 will be about the same price as the smoothie 1. The smoothie 2 pro will be $200+.
Awesome Arthur, looking forward to this one…
4 Servo outputs, nice! No RS485 or CAN, right?
@Jonathan_Lussier No, will require a small adapter.
Will there be a version with no drivers?
@y_milord There will be a version with only 3 drivers. potentially we can do a version with no drivers at all if there is enough demand.
I’d be interested. The machine i’d like to use this has large NEMA 23’s with external drivers. Something like that would be a drop in replacement.
Oh man, you’re going to get busted for posting porn on google+.
Sooo…ARM Cortex M0 or M4? Also, I see “Intel Edison” printed on the board? What is that for? And “FPGA_JTAG”? Will the FPGA be for debugging only or is there something more interesting planned?
NXP LPC4337 (ARM Cortex-M4 which includes an ARM Cortex-M0 coprocessor). And the Edison is for running a host (i.e. Octoprint) locally on the controller.
Will you need 4A? The drivers spec’d on the previous announcement show 4A drivers. I don’t know if that changed.
OK, servos, Edison, many motors, many outputs, better alignment of aditional pins, screws with some space around. Definetly looks like perfect replacement of my semifryied Smothieboard ver.1 Thanks for this work and good luck with testing and finalizing.
RC servos, servomotors or both?
@Arthur_Wolf If you you are looking for beta testers. I’d like to throw my name in the ‘hat’ so to speak.
@Jeff_DeMaagd RC-style servos (3-pin). You can use “real” servodrivers/servomotors on the unused stepper driver circuits if they support the same protocol type.
it wasn’t until I looked at the underside of the PCB that I realised what it is you had done, There didn’t seem to be enough driver chips to run all seven Motors… However, Putting two extra drivers on the underside? yes, that’s clever, and rather well thought out. Though it does mean that one has to think carefully about location of the board now.
There is a Xilinx Spartan FPGA on the board! What is that used for?
