My company needs a new PCB designed to drive a stepper motor. We use an RS485 network, and the controller/driver has to be (very) small.
Drive 1 (one) 4 wire stepper motor at +/- 2A per phase
Have input for 1 (one) limit switch
Have outputs for 2 (two) solenoid valves
Communicate with host controller via RS485
Receive position commands from network and go to/maintain position with no further instruction
Must have single ended pressure sensor on board
Must fit on PCB no larger than [url removed, login to view] diameter (dual sided acceptable)
Must have at least three stand off positions
Functional prototype for testing (need not be on 2.5 inch diameter PCB)
All Gerber files
Bill of materials
