Hi
C4, C7, and C8 are filter capacitors, usually 0.1uF, 10uf.
Which Res you want to know?
Thank you for your reply!
I would like to know to add J1 plug-in, besides C4,C7,C8, do I need to solder other components? if yes, please tell me which ones and values.
And could you please provide me with the model number of the J1 connector?
thanks!
Engineer will give you response tomorrow.
Thank you for your patience in advance.
Hi Zhou,
The two unsoldered chips are about the I2C. One chip provides the voltage of the pull-up resistor to the IIC, and the other chip acts as the IIC level shift.
If you don't use it, you can ignore it.
You can take another look at the schematic and user guide of the EVM.
