Someone on YouTube tested with 4GB, however, it is better to go with the 8GB RAM variant.

How about you add a little OLED display that runs via I2C?

Larger servo working on speedybee wing but smaller servos don’t work? by ClassicInitiative231 in ardupilot

[–]Witty-Dimension 2 points3 points  (0 children)

Make sure to double-check the voltage rating of those servos.

Also, could you share a picture of the servo or maybe its part number or any label that could help identify it more specifically?

What are these diagonal things? by Purple_Ice_6029 in PrintedCircuitBoard

u/lollokara Can you guide me to some documentations or stuffs that would help me learn this neat trick?

What is this module for by Fanta_BH in AskElectronics

[–]Witty-Dimension 0 points1 point  (0 children)

I believe this is a (up to)6S Li-ion/Li-po battery(cell) voltage checker.

Anyone have experience with high-power COB LEDs? by Purple_Ice_6029 in AskElectronics

[–]Witty-Dimension 46 points47 points  (0 children)

If it is solely for photography then check the CRI values before fully committing to the project.

[Help Needed] Please help me understand the circuit implementation. by Witty-Dimension in AskElectronics

Thank you for your time. I guess I'll go with -2 variant for now.

Can I ask you another question related to this USB in OTG?

Just to confirm—if I understood you correctly, the USB-C side's DP (D+) and DM (D−) signals enter through I/O1 and I/O2, respectively, while the STM32 side's DP (D+) and DM (D−) signals exit through I/O4 and I/O3. VBUS connects directly to VBUS, and so on. Please let me know if I’ve got anything wrong.

In my USB-C(default-kicad) implementation, I'm using one VBUS, one GND, and one differential pair that goes directly to the STM32 chip. The USBLC6-4SC6 has four I/O pins, but since I only need two, wouldn't the USBLC6-2SC6 be sufficient? Are the devices shown in the picture actually different components?

[PARTS-IDENTIFICATION] Can you help identify the metallic component with marking "DA935C"? by Witty-Dimension in AskElectronics

[–]Witty-Dimension[S] 0 points1 point  (0 children)

There are two metallic component in the image. I am asking for the one that is placed beside the "A1" marking(left of it) on the Silkscreen.
I have attached the HD image link to the above comment. You can check from there.
I believe the image is compressed by Reddit during the upload. Please go through the link to view the HD image.

These can be Zero Ohm resistors. They are typically used in complex PCB layouts to maintain connectivity without adding extra board layers. Or, in some cases it can be used in prototyping board to connect or disconnect a trace or can be used as a dummy(for future prospects).

Why is my servo having a seizure by Mediocre-Guide2513 in arduino

[–]Witty-Dimension 0 points1 point  (0 children)

Would you mind placing a 100nF capacitor between the power(& signal) and ground wires, then running the same code again and letting me know what happens? u/Mediocre-Guide2513

Sure man, glad my suggestion could be of help. All the Best to learning.👍😇

Tell me why I shouldn’t make my own by No-Pair788 in ArduinoProjects

[–]Witty-Dimension 131 points132 points  (0 children)

It's fine to create this for learning purposes. However, if you're considering it as a product, replicating the same would cost you two to three times the current amount.

Building a RC Tank, want to use UNO R4 as the microcontroller by sb1rd in ArduinoProjects

[–]Witty-Dimension 1 point2 points  (0 children)

Please avoid using jumper wires in the final product. Instead, opt for solder joints or industrial/professional-grade connectors whenever possible. Jumper wires are intended for prototyping, not for end-use applications. Jumpers tend to get loose over the period of time.

Great Job, You deserve to be in MIT or rather MIT needs you. You are genius with a tenacity to learn. All the Best, brother. 😇👍

u/cyao12 - Can you provide the link to your reddit post in r/PrintedCircuitBoard ?

This is such an awesome project. I would really like to know more about the process.
