Here’s an overview of the selected items and their roles in your schematic:
Table
| Component(s)/Net | Type | Value / Properties | Function |
|---|---|---|---|
| C1, C2, C3, C4, C5, C6, C7, C25 | Decoupling capacitors (8×) | 100 nF, SMD 0402 (Yageo CC0402KRX7R7BB104) | Placed close to power pins of U1/U2/etc., these capacitors filter high-frequency noise and stabilize the local +3.3 V rail. |
| C8 | Bulk decoupling capacitor | 1 µF, SMD 0402 (Yageo CC0402KRX5R6BB105) | Provides additional charge reservoir on the +3.3 V rail to handle larger transient currents and improve low-frequency stability. |
| 3V3 | Power Net Portal | 3.3 V supply | Distributes the 3.3 V power rail from the regulator to all powered components on the board. |
| MICROCONTROLLER | Text Note | “C11 should be close to pin 45 of RP2040” | Schematic annotation reminding you to place the decoupling capacitor C11 as close as possible to the RP2040’s VDD pin for optimal performance. |
- The eight 100 nF capacitors (C1, C2, C3, C4, C5, C6, C7, C25) handle high-frequency decoupling, suppressing fast transients on the +3.3 V rail.
- The 1 µF capacitor (C8) provides bulk filtering for slower transients.
- The +3V3 net portal marks and connects the board’s main 3.3 V supply.
- The “MICROCONTROLLER” note is a placement guideline to ensure effective decoupling of the RP2040.
