Is this compatible with Bluno Uno?

Is the documentation wrong - I found that:
D4 is motor 1 direction
D5 is motor 1 PWM
JaneYu Hi, Really sorry about it, You are right. We forgot to update the English wiki. Here's the correct one as you mentioned but it's in chinese. We will fix the English documentation soon. https://uploads.disquscdn.c...
Is the heat discipation & passive cooling enough? What are your experiences with this PowerSO casing? May it be able to deliver constantly 1.5A?
JaneYu It's definitely possible & useful, if you use it with another controller, for ex. with an RPi or NodeMCU.
Althouth I think, you, @dfrobot:disqus misunderstood @mohamaddaniel:disqus. He meant hardwiring the arduino; i.e. not directly attaching this board to is.
JaneYu i just build an arduino car control via bluetooth but it cannot reverse..only left,right and forward....why??
i am using 2A Motor Driver Shield L298P..
JaneYu The direction control of the motor driver shield is by pin 4 & 7, how do you use bluetooth to control your car?
Cherudim is right, this motor driver can't afford this kind of motor, including 12V ones ( it should work without any payload), recommend a high performance one: https://www.dfrobot.com/ind...
JaneYu No, it means the GPIO is not enough to supports this function. But could you share what do you want to do with 7 motors? And what is your request for the motor spec? 12V, 24V or more?
JaneYu Hi friends!
So I'm trying to run two 3v motors off the motor shield. When I run code that runs one motor, it runs fine. However when I try to run two motors off the shield, they struggle and cannot turn but are clearly trying to. I am using just a regular 9v battery to power the shield. Any ideas on what the problem could be? cheers
JaneYu As you can understand I'm not an expert here... so a module, a shield, whatever it is there's a way to connect it to Arduino and LCD????
JaneYu Hi Teo, Arduino shield could plug on the Arduino board directly, but module, you could use jumper wire to connect them. follow the wiki, you'll get it. And LCD are not a problem. The keypad shield has reserved some pins for the other function. just connect them with the motor, It isn't difficult, just combine their wiki. be patient!
Thanks for your advice, I've seen this motor driver 2x15A-Lite but how can I connect it with Arduino togheter LCD shield? I dont' see any pins
JaneYu This is a single board which you need to connect driver board with cable. It is not convenient, but your motor requires this kind of motor driver.
can this work with arduino due without having any problem?
JaneYu Sure!, this is an arduino expansion shield
HI, there are two jumper caps beside the power port, if you want to power motor + arduino together, you can connect in this way. But I need to say, if motor and MCU are using the same power resource, the motor noisy will affect MCU stability
JaneYu hi,i have a query as i was facing some problems during constructing a dual axis solar tracker, i am using 2 bipolar stepper motors,for that i was using 2 L298N drivers to a single arduino uno R3 board,what should i prefer,wheather using these drivers or using a shield would be better?
JaneYu Stepper motor one, you need to control the rotation angle, not the speed, stepper motor does better.
Since this shield uses 4 specific pins without any option to change which ones, how could you possibly use more than 1 DFRobot motor shield at a time?
JaneYu There are some jumper caps on the shield, you can connect other pins with these pins
This motor shield is using L298P, it is totally enough for 3 or 6V motors
JaneYu Hi guys, I just want to control 4 dc motors and 2 servo motors. so How many boards do I require?
JaneYu Hi. I'm newer in this job. So, I have question.
I have one DC motor with spec (24 VDc and 0.85 mA), one Arduino Uno and one DF Robot Motor Shield (2A).
Could DC Motor operated well with DF Robot Shield?
Could You give me advise about power supply for motor shield, arduino and DC motor? How the best arrangement for those?
Thank You.
JaneYu Hi, the peak current of this motor shield is 2A, It means the motor start current can't over 2A. It is better to check the motor spec "stall current" first. Or I'll recommend this one http://www.dfrobot.com/inde...
hi
i am using and arduino L298P shield for One motor. The program is correct. Everything is correct. But motors wont work.. It works only if i touch the PWM 12 pin (which is initialized as the output pin for my program) with my finger. Other wise the motor doesn't work.
I am using an arduino UNO r3 and a dc motor, with a 7.5V 1500MAH external supply... still the problem exists....
Can anyone please give me a solution for this??
JaneYu Hi, if everything goes well, it should work. so there must be something wrong. Do you have a multimeter? Could measure the voltage of 4 drive pins? Or you could contact with our dfrobot techsupport team directly [email protected]
Hi, sorry for the late reply, What is your PWM value, if the PWM value is too small, it will not enough to drive the motor, for turtle, it should be higher than 100 under 9V power supply.
JaneYu Is this shield compatible with Galileo Gen2? I bought them together they seem not to work. Any suggestions?
JaneYu Hi, I am sorry, we didn't test it with Galileo, but in theory, it should be OK. Do you have another Arduino board? like UNO? Could you test it whether the hardware is OK? And it is better to measure the voltage with motor driver. I remmebner there is a design flaw with Intel Edison power system, but I am not sure whether it also happens on Galileo.
