Question about reset RC and boot network

[n47h4n]

Hi,

In Espressif documentations (ESP32-S2, S3, C3) it is adviced to use a RC network made of 10k resistor to VCC and 1uF capacitor to GND.
But in most schematics a 0.1uF capacitor is used.
My question is what value one must use?

Same for "boot" pin. 1k resistor and 10pF capacitor. Is that good?

Thanks for your responses.

For the reset, it depends on your power setup (slow rising power needs a larger capacitor) as well as the way you program the board: if you use the two-transistor auto-download mode circuit, some PCs/OSses need a slower reset requiring a larger capacitor. If you use internal USB for programming and have a fast-rising power supply (e.g. USB with a LDO with not too much decoupling capacitance), an 0.1uF + 10K will suffice.

No idea what that 10pF is good for (especially as the switch probably has a parasitic capacitance in the same order of magnitude), where do you see that?

@ESP_Sprite thanks

About the 10pF capacitor, I saw it on this schematic https://files.seeedstudio.com/wiki/XIAO ... C3-SCH.pdf
I think you are right. It must be there to avoid parasitic bounces on the button.
