Kamiquasi on DEV-11114 - Arduino Pro Mini 328 - 3.3V/8MHz
Yes, but keep i mind that you’ll want to connect to the RAW pad, not VCC. If you’d like to just plug in a USB cable and also communicate with it, check out the Pro Micro – 3.3V/8MHz

Yes, but keep in mind that these have a fairly high current draw, so if you add more than one you can quickly reach the maximum current draw allowed from your USB port. Check out some of the other...

Am I the first one to notice this… the JST polarity is the wrong way round!

About the voltage divider, doesn’t the RXO voltage depend on the current? The RX output of 2.5 V is correct only if the current is zero. Suppose there is a current as low as 0.16 mA (toward to the...

Yes, yes it is. It applies to one and applies triply so for 3 ;)

Is it possible to dynamically change the stepping resolution whilst the motor is running? It would be useful to be able to use a lower resolution at higher speeds so as to improve torque.

I want to set up a temperature monitor with an ethernet interface – for something that simple it seems almost criminal to use something like Raspberry Pi… But this board is actually more expensive –...

Yeah, these are not great components. As below, the screws don’t thread cleanly making for a sloppy fit. That said, they’re ridiculously cheap, so I’m not sure I should have expected better.

Can one of these be modified to be powered with batteries? I’m looking to power an A4 EL sheet but need it to be portable, powered by 8 AAs. Also, if i could mod, would one of these be enough to power...

Should be fine for the A4 sheet (note that you can’t easily ‘mix’ two inverters anyway, so if there were an issue, you’d have to find a more beefy one instead).If you already have a battery holder and...

Thank you so much for the great tutorial. I’ve done quite a few done with a skillet, and think it’s the best method for one-offs. You just know when to stop the heat.Aki

Diffused will give you a more even glow. If you are using these under the button pads though, it may dim the colors shining through a bit. I’d check the forums to see how it looks if anyone else has...

For the Arduino Uno it is center-positive (barrel/sleeve-negative). I suspect it depends on what your application is. Use a multimeter to be sure.
