@copilot create a high level mermaid block diagram of this project. Include key component's manufacturer part number in each block whenever possible.

Sure, I can help create a high-level block diagram using Mermaid syntax. Based on your components, here's a block diagram that includes each key component and its manufacturer part number.

Let's verify that all reset and enable pins in the project have the necessary pull-up or pull-down resistors. Here are the relevant components:
  1. ESP32-WROOM-32 ($U1$)
    • Reset Pin (EN): This pin should have an RC delay circuit.
  2. TPA3144D2PWP ($IC1$)
    • Shutdown Pin (~SD): This pin should usually have an external pull-up resistor.
    • Fault Pin (~FAULT): This pin should usually have an external pull-up resistor.
External Pull-up/Pull-down Resistor Requirements:
  1. ESP32-WROOM-32 (U1: EN)
    • Recommended RC delay circuit: Resistor (10kΩ) and Capacitor (1µF).
  2. TPA3144D2PWP (IC1: ~SD and ~FAULT)
    • Shutdown Pin (~SD) requires a pull-up resistor (let's assume a typical value of 10kΩ if not specified).
    • Fault Pin (~FAULT) requires a pull-up resistor (let's assume a typical value of 10kΩ if not specified).
Action Items:
  1. Add a 10kΩ pull-up resistor to the ~SD pin of IC1.
    • Connect a 10kΩ resistor between $IC1:~SD$ and a 3.3V power supply.
  2. Add a 10kΩ pull-up resistor to the ~FAULT pin of IC1.
    • Connect a 10kΩ resistor between $IC1:~FAULT$ and a 3.3V power supply.
  3. Implement the RC delay circuit for the EN pin of U1 (ESP32-WROOM-32).
    • Connect a 10kΩ resistor and a 1µF capacitor in series between $U1:EN$ and GND.
    • Ensure that the junction between the resistor and capacitor connects to $U1:EN$.
Specific Connection Steps:
  1. Pull-up for ~SD Pin on IC1:
    • Connect R1:1 (10kΩ resistor) to $IC1:~SD$.
    • Connect R1:2 to 3.3V.
  2. Pull-up for ~FAULT Pin on IC1:
    • Connect R2:1 (10kΩ resistor) to $IC1:~FAULT$.
    • Connect R2:2 to 3.3V.
  3. RC Delay for EN Pin on U1:
    • Connect R3:1 (10kΩ resistor) to $U1:EN$.
    • Connect R3:2 to the junction between C1:1 (1µF capacitor) and C1:2.
    • Connect C1:2 to GND.
If you prefer different resistor or capacitor values, please let me know.
