Hi Community,
Just wanted to confirm a value of resistor. Referring to power shield v210 .brb and .sch files available on github.
R17, R18, R19 & R20 is showing a resistance value of “4K7”. I am not very affluent in hardware, just wanted to confirm if this is 4.7K of 47K Ohm resistor. (Package # is 0402)
Thanks
4.7k
We usually use the k
as the decimal and denomination
But to be sure, let me check.
Update: I checked against the datasheet and yes 4.7k!

4k7 = 4700Ohm
Because engineers are efficient creatures
For brevity, the notation omits to always specify the unit (ohm or farad) explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors,[nb 1] the case used (uppercase letters are typically used for resistors, lowercase letters for capacitors),[nb 2] a part's appearance, and the context. The notation also avoids using a decimal separator and replaces it by a letter associated with the prefix symbol for the particular valu...

And the award for the most embarrassing post ever on Particle goes to …
Actually i was checking the sparkfun library as well … that kind of made me ask and re-confirm
Thanks @Moors7 & @kennethlimcp
Trust me, i knew it through asking last time
