Re: Dual A3697 Stepper Motor Driver Shield (HCARDU0103)

The issue I'm having is that with 12v plugged into the motor board everything works for so long, ie the motors ramp up and down in speed, and then reverse. I have noticed that the driver chips get incredibly hot after ten or so seconds, and then one or both motors run erratically. This sounds like ...

Re: 7" Colour TFT display with driver board (HCMODU0096)

If you turn the controller board over you will see the pinnout for the connector in silkscreen on the underside. This is as follows: IR-VCC GND IR POWER MENU +++++ ------ SOURCE LED-G LED-R If you need to change the input you just need to connect the SOURCE pin to the GND pin using a wire or a switc...

Re: Advice on soldering

There is a lot of soldering to be done for the 8x8x8 cube kit but I certainly would expect you to be getting trough several tips. If you're using very fine tips it wouldn't be unusual to wear a tip out but not several. Does your soldering iron have an adjustable temperature? If so you'll want to set...

No, we don't stock that board I'm afraid.

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Sorry for the confusion. If you take a look at the push buttons you will notice that 2 of the legs protrude out of one side of the switch and the other two out of the opposite side. This makes the switch slightly wider which means it can only be inserted into the PCB in one of two possible orientati...

Re: 7" Colour TFT display with driver board (HCMODU0096)

what is the connector type ? is mini jst 1.25mm, mini jst 1.0mm or mini jst 2.54mm ? I believe it's some sort of FFC type connector with a pitch of 0.5mm Just to point out if your using the screen with your own custom board please be careful with the ribbon cable where it enters the screen as it's ...

Re: 0.9" 128 x 32 Serial I2C uOLED Display (HCMODU0118 & 119)

I've been able to replicate the problem and have uploaded an updated version of the library. I don't have access to a display to test it with at the moment but hopefully it has fixed the issue. You can download the new version (V0.5) from the software section of the forum here: https://forum.hobbyco...

Re: EDTracker Bundle (HCKITS0021, 21B, 21E, 21F, 21G, 21H & 21I)

Thanks for checking. The sketch should continually output readings from the MPU9250. From your results it looks like it's either a problem with the MPU9250 itself, or the connection form the Pro Micro to it. I doubt the problem is with the Pro Micro. I know you have already double checked the connec...

Sorry to hear this and thanks for your very thorough post. As you seem to be familiar with using the Arduino IDE could you possibly give the example sketch in the first post of this thread a try: http://forum.hobbycomponents.com/viewtopic.php?f=73&t=1956 Just cut and paste it to the IDE and upload i...
