Which datasheet example would you like me to follow?
- The RP2040’s reference design (power decoupling, reset pull-up, flash wiring, VBUS sense, etc.)
- The W25Q32JV flash example circuit
- The USB-C connector reference (CC pull-downs, VCONN, dead-battery path)
Or let me know if it’s another section—and I can assume you want the RP2040 reference design if that works.

I can add the five 100 nF capacitors to implement the RP2040 decoupling. They are:
- CL10B104KB8NNNC (0603, 100 nF, X7R, 50 V)
Shall I apply this change?
