Well, i do know there exists an R3 that has a clone just like it and i find plenty of videos for it.. but not for this one, i actually need this one to not have a spaghetti project, wires everywhere and all of that stuff.. i also couldn't make out what brand made it so i can't find which pins lead where.. i don't have it yet, but i need to know before i burn anything..
This clone has a very specific vendor (Micromaroc). If you bought this board from them, you can write them and ask for the pinout specs.
Otherwise, maybe this page will give you some tips:
I think they may be inputs for the A/D but as @Brazilino suggested contact the manufacture for the correct description and let us know.
The "S" pin name and the arrangement of 5V and GND suggests a convenient place to plug in a servo but the power requirements of that many servos would be problematic.
Hi @novahmakesthings. From looking at the manufacturer's website at the link @Brazilino provided, I think it is clear that these are the Arduino Pins A0 - A5.
Note that these aren't extra analog pins. They are electrically identical to the A0 - A5 pins on the black female header. They are simply laid out in a manner that may allow more convenient connections to those pins in the use case where you need 5 V, ground, and an analog pin and have a 3x1 female dupont connector on a cable that can plug right in to the column of three pins on those male headers.
well, i'm just unsure of the blue "S", because the number exactly matches that of the analog pins.. but on another hand, i don't wanna fry anything
It was just a guess since there was no documentation for your actual board linked. Take your DMM and trace out the continuity to the A0-A5 pins to be certain. The "S" label probably just stands for "signal".
omg thank you so much, seems to be the exact model! i'll also ask just to make sure.
that's what i guessed! thanks for the info!
Make a simple check.
Feed 3.3V at A0-pin by a jumper. Measure the voltage at A0(?)-pin of the blue color header to see that it is also 3.3V. However, the legend 'S' is confusing -- if it would an anlog pin, then 'A' would be justified.
Note that the "analog" pins can also be used as normal digital pins. ADC is only an additional capability on top of the standard GPIO capability of the pins. This is similar to how some pins have an additional UART, SPI, or I2C capability.
For the speculated use case of plugging a standard hobby servo's dupont connector onto these headers, the blue pins will indeed be used as a "signal".
