A200SMC -- A-200 Stepper Motor Controller The A-200 Stepper Motor Controller is based on the design of the A-100, and offers the power to handle larger, more powerful NEMA 23 stepper motors. The A-200 is used to control unipolar stepper motors up to 3A per phase. It has a 25-pin connector and connects to a PC through a parallel cable, or it can also be controller by a microcontroller or other device capable of ttl-level outputs. The software for the A200SMC controller, including in the standalone Windows program and the .dll, are included in the price of the A-200, which sells for only $70.00! The A-200 also has multiple diodes and optoisolator chips for reliable operation and to provide maximum protection for your PC. We also offer a number of motors that are ideal for use with the A-200. To encourage the use of these motors, you receive a $3 discount off the price of each motor purchased with a controller board. See our order form for more info. A-200 Specifications # of Motors Controlled 1 or 2 Computer Interface Parallel Port Max Motor Current 3A per channel Motor Connection 6 Position Terminal Blocks Power Jack .215" (5.5mm), Center Positive Board Dimensions 3.5"x1.9" # of Mounting Holes 3 As mentioned above, the A200SMC can be controller from any device capable of ttl-level outputs. To see how the devices communicate with the A-200 controller to cause the stepper motors to rotate, take a look at this page on the A100SMC and A200SMC parallel communications. Optional Accessories To complete your motion control system you can chose from these products that we also offer: (representative picture) PSUPPLY1 -- 12V, 1A power supply -- $5.00 PSUPPLY3 -- 5V, 2A power supply -- $20.00 PSUPPLY4 -- 6V, 1A power supply -- $5.00 PCABLE6 These parallel port cables have all 25 pins connected through for complete and accurate stepping.  They are 6' in length, and are recommended for use with both the A-100 and A-200 controllers. Cost: $5.00
