Propeller-Robot-ControlBoard #28230 + 2 x 12 volt VDC - motors

nomad · 2010-04-08 07:08

hi,
i want buy the PropellerRobotControlBoard
# 28230
with this board i want control
2 x 12volt VDC-Motors with a single
12volt Batterie with 3.7Ah.
aka for each motor with max 1.85Ampere.

Question (1): is this possible with this Board ???
(the Board have 2.8ampere each channel)

Question (2): on the Board-Doku.pdf
"28230-propellerrobotcontrolbrd-v1.0.pdf"
on page 5
quotation:

CAUTION: The input voltage (VIN) is also the motor voltage.
For this reason you should not use a wall adapter or battery higher
than the maximum voltage of the motors when enabling the motors
(power switch moved to the third (right) position, see below) or you
may damage or reduce the life of the motors.

is this important for me???
i think, when the input (from 12volt batterie)
output (to 2 x 12vollt VDC-Motors)
its ok ????
but my english is not so good

thanks for tips, hints and help
regards
nomad

The robot controller board can handle 12V. Just make sure that neither of your motors draw more than 2.8 As per channel.

I've tried 12V input with the board. Everything works fine.

I have just bought the same setup. Works great! I use 10 penlite batteries (AA 3900 mAh)
if you need any code to start from let me know. I just finished the basic drive setup.

hi Botdocter
excuse this second posting
if you have code-sniippets for the start please make a attachment
im working with 2 motors + 12VBatterie + this Board + the PropellerProfessionalDevelopmentBoard
1 x compass, 7 x Pings
thanks for your help and the code
regards nomad

The code is cleaned up and should work out of the box. Just remember to change the PING))) Pin to whatever pin your using
You don't have to change the motor pins since the connectors have default pins and are filled in allready.

:::::::Code is attached to this post :::::::::

Enjoy!

-> SetField( x_pos, y_pos - sectordist, 2 ) with
-> expected an instruction or variable
in your code i find nothing about this instructions???
have you some hints or tips???
thanks for the code and the pwm-object

You can remove those lines. They're from some other code im working on.
You will see that same sentence three times. Just remove them.
