  • Devantech 8-Channel, 1A Optically Isolated USB Relay Module
    excelent
    Review by David
    Product is working better than expected. One part that was returned was promptly replaced.

  • Devantech CMPS03 Magnetic Compass Module
    Devantech Magnetic Compass Module CMPS03
    Review by OFK_Tech
    These devices measure the earth’s magnetic field in 2 axis and can give orientation. Calibration is a big challenge on FRC robot projects.
    Ferrous metals and magnets in parts of robot will affect the compass. You need to calibrate them against these affects with a desirable margin of errors.
    -The compass has 2 axis. If there is any tilt the reading will be way off.
    -This compass does not output an analog voltage.
    -The rise and fall time is fast
    -The ADC in the robot controller works fast enough
    -Byte values can be read over an I2C bus.

  • Devantech 8-Channel, 1A Optically Isolated USB Relay Module
    As good as it gets!
    Review by GiGa
    Does perform exactly as expected, good quality components.

    To integrate it in our design we required RoHS certificate and 3D dimensions, response from Devantech support was very fast and complete.

Build Your Own 4bit Digital Compass

Posted on August 14, 2006

By William Cox & filled under Electronics.

Here’s a nifty project I found off of Hackaday – how to build your own 16 point (4bit) digital compass. Instead of using the popular 3bit Dinsmore compass the author decided to build his own. The author attached a magnet to a reflective encoding disk. Using four infrared photoreflectors he was able to read the [...]

New Ultrasonic Sensor for Hobbyists

Posted on February 24, 2006

By William Cox & filled under RobotShop.

Look out Devantech, there’s a new kid on the proverbial block, the robotics-block, that is. While the ultrasonic sensor line from Devantech has turned into a staple for many hobby robots, it looks like there might be another viable contender. Check out the Ultrasonic Range Finder from Maxbotix, which is listed for $24. A FAQ [...]

A Review of the OOPic 2

Posted on May 29, 2005

By William Cox & filled under Reviews.

This is a review of Savage Innovation’s new microcontroller, the OOPic 2 By now, all the regular readers here at The GoRobotics Network are probably aware of the OOPic processors. This little beauty is loaded with great features (and a great price) that make it quite attractive to robot builders. If you aren’t familiar with [...]

Hi jedy,

Welcome to the RobotShop forum..!

The Devantech MD03 (RB-Dev-04) motor controller has an input Voltage of 5-24VDC.
Our Datasheet on the website is wrong, we will be correcting this and thanks for letting us know of that.

We added the manufacturer datasheet as attachment for you here.

... wire that you are using (from Digikey) would connect the StarGazer module to the motor controller on your robot--an Arduino motor controller or Devantech, etc, if you are using those brands. I have not yet completed this step, so I can't advise you (yet) on this StarGazer-to-motor-controller ...

Voltage is 3.3V and serial set to 9600, 8 data (not actually specified in doc, but necessary to get 0-255 as a 1 byte result),no parity, 2 stop bits.
Serial is at 3.3V drive level.
Compass seems to work in pwm mode, so its alive.
Maybe need to ask Devantech?
