Re: Motor control : which accessories for the Raspberry PI

... continuous load which will handle most motors of that size. There is also the SN754410. It is pin-compatible with the L293D, but has a 1A rating. 'Piggyback' chips and heat-sinks are other ways to increase the power handling capacity. See the "I Need More Power" section of this post http://forums.adafruit.com/viewtopic.php?f=31&t=26873

need an answer about protoboards

... a protyping board for the raspberry pi specifically the product #1148 Because of the small space I am putting this project in, I am wanting to piggyback a board on top of it with spacers. I was wondering if the product #1214 holes lined up with the four holes on the product #1148. If not, do ...

Re: Real time clock cannot be set

Hello - I just wanted to piggyback on this posting as I am having the same problem. I am using a Mega R3. Instead of the data logger, I am using the RTC DS1307 and the microSD breakout board (https://www.adafruit.com/product/254z). My ...

Re: Waveshield TS922 Vs TS922IN

... draw as much current as the amp can deliver, but it won't hurt anything. 4) As the TLV2464 gives out 1/8 W to an 8 Ohm speaker ... does that mean piggybacked it gives 1/4W to an 8 Ohm Speaker Each op amp in the package can deliver 100mA, but the amps are doubled up to get a total of 200mA.

Re: Waveshield TS922 Vs TS922IN

Yeah, you should be able to piggyback those two chips. Their specs are mostly the same, and they're both known to work in the Wave Shield. Another option would be to send the output through one of our class-D amplifiers. They come in power ...

Waveshield TS922 Vs TS922IN

Ok... I have the Waveshield and wanted to increase the volume (about 50%) so I decided to piggyback a chip as recommended. I inadvertently ordered and TS922IN which is much smaller. But have now realised that I have the new TLV2462 Amp on the Waveshield , not the 922 ...

Connect Multiple Arduino Unos

... temp sensor UNO board to the main board that has the wifi that will then post the data to our cloud server.Hence, we want our sensor board UNO to piggyback the wifi UNO. We have both boards working independently now, but not sure how to "daisy chain" together

Re: limit amps to stepper motor?

... the motor can do will hurt the driver. One easy way to get more power is to wire multiple Darlingtons in parallel. On a circuit board you can piggyback one chip on top of another to double the power capacity, but that causes some problems with heat dissipation. If you're building the circuit ...

Re: Motor Shield V2 Unequal Steps

... think it's possible that I'm not getting enough current into the motors and do you have any suggestions on how to get more? Has anybody tried to piggyback a second TB6612FNG driver chip? Dave

Re: Motorshield, Stacked SN754410, and Steppers, Oh My!

At this point I would suspect either a problem with your piggyback assemblies, or the motors themselves are pulling too much current. Plug the chips back in, but disconnect the motors. Does the problem come back? I will try this tonight. Since we know ...

Re: Can I drive a Kysan 1124090 stepper with Motor Shield V2

... 2) Probably not. 3) A lower voltage would be safe, but as you suspect it would yield a lower torque. I don't know if anyone has tried to piggyback the chips on the V2 shield. In theory, it could work. Another option would be to use a constant-current "Chopper" drive: https://learn.adafruit.com/all-about-stepper-motors/matching-the-driver-to-the-stepper
