Summary
1. Parts List
2. Configure the BS0710 Jumpers
First Use
This example makes use of the following components:
connection of the power supply to the BOE and the BS0710.
For tools, you will need (at least)
Items 6 (the ‘9 volt battery adapter) and 7 (small breadboard from Radio Shack) simplify the
1. 1 A-BS0710USB-TTT-GS dual axis stepper motor controller
2. 2 Parallax 12V 100 ohm unipolar stepper motors (for educational use only)
3. Parallax Board Of Education (BOE)
4. Parallax Basic Stamp, the BS2
5. A single 12 volt 1 amp (or more) regulated DC power supply. This may be either switching
6. A 9 volt battery adapter
7. In our case, we also added a small breadboard from Radio Shack to simplify our wiring of the
1. A wire cutter/stripper
2. A 2.0 mm jeweler’s flat-blade screwdriver (to connect wires to the BS0710 screw terminals)
The BS0710 has several jumpers that are used to control how the board is powered, how it
communicates with the outside world, and how it operates the motors.
For the purposes of this application, the jumpers should be:
A picture of the portion of the board shown with the jumpers correctly positioned follows:
(note that the JS jumper is positioned so that only one pin is connected to the jumper; this allows
you to not lose the jumper….)
or linear; it should also be grounded.
power from the power supply to both the BOE and the BS0710.
