Dear Sir/ Madam,
About i.MX8M Mini EVK Base Board:
1. would you please help to explain the function for R301=47K, C303=0.01uF and C323=0.01uF?
2. Why C303 has DNP?
3. Why there is no 47K ohm next to C323?
Thanks!
Wenwen
Hi Wenwen,
>>1.would you please help to explain the function for R301=47K, C303=0.01uF and C323=0.01uF?
C303 & C323 are both filtering capacitor, which are used to filter high frequency signals attached on DC power.
For R301=47K, I didn't find the resistor in the schematic of i.MX8M Mini Base baord.
>>Why C303 has DNP?
No, it is not DNP.
>> Why there is no 47K ohm next to C323?
I don't know why you ask the question, where do you want to add 47K?
Have a nice day!
B.R,
Weidong
