We support USB for all of our non-USB boards, with our USBToTTL USB to TTL serial converter. This product allows you to have a panel or box-mounted USB connection that can then be routed to any of our RS232 or TTL-Serial based motor controller boards.
We also offer an RS232ToTTL RS232 to TTL serial converter that can be used at any time that an RS232 connection is needed to any TTL-Serial compliant device (such as most of our USB motor controllers).

"Voltage Mode" Non-Current Regulating Products
For these products, current output to the stepper motor(s) is controlled by the voltage of the user-provided power supply, combined with the winding resistance of your motors. Please review the calculating motor current faq in order to determine the current and voltage requirements for your motor before selecting a controller.
All of these products are good for simple low-speed operation of multiple stepper motors.
The following table summarizes the capabilities of the currently released non-current regulating motor controller products. Please click on the product name for more information about that product.
| Product | TTL-Serial Support | On-board RS232 | On-board USB | Unipolar | Bipolar | Maximum Number of Motors | Current/Winding with 2 motors | Double Current Current/Winding with 1 motor, using GenStepper firmware | Motor Voltages |
| SS0705CR | x | x | x | 2 | up to 0.5 Amp | up to 1.0 Amp | 5-26 | ||
| SS1010-USB | x | x | x | 2 | up to 1.0 Amp | not supported | 5-26 | ||
| SS0905USB | x | x | x | 2 | up to 0.5 Amp | up to 1.0 Amp | 5-26 | ||
| BS1010-USB | x | x | x | x | 2 | up to 1.0 Amp | up to 2.0 Amp | 5-34 |
These products allow you to specify the target winding current to use during motion operations. They all use a "chopper"-based current regulating technique in order to regulate the winding current, and are excellent choices for high speed motion control. Please review the calculating motor current for current controlled products in order to determine the current and voltage requirements for your motor before selecting a controller.

Step-And-Direction Controllers
We now offer the SD4DX series of step-and-direction controllers, each of which being capable of direction the actions of up to 4 external step-and-direction motor driver boards (such as those produced by Applied Motion and Gecko). Please click here for more information about that product.
Generic Digital I/O Control
Many of our boards can be factory reprogrammed to be generic digital I/O products as opposed to being stepper motor controllers.
The SerRoute firmware changes our SimStep and BiStep series of boards into TTL-Serial routers, which also provide for generic encoder support (reading of up to 8 encoders), serial routing (for example, up to 9 'child' boards may be connected to one 'parent' SS0705USB board), as well as generic I/O control. Please click here for more information about the SerRoute firmware.
Serial Communications mini-boards
We offer 3 mini-board solutions to generic serial communications. Any of the three may be used with each other to create special purpose systems (such as ultra-long-range USB communications or USB to RS232 converters), and they may be used with any product (such as most of our motor controllers) that support TTL-Serial operations.| Product | Description |
| USBToTTL | Allows USB communication with any TTL-Serial compatible device |
| RS232ToTTL | Allows RS232 communication with any TTL-Serial compatible device |
| RS422ToTTL | Allows very long communication paths between TTL-Serial compatible devices |
