how should I connect the shield pin?

@copilot how should I connect the shield pin?

The shield pin of the USB-C receptacle (J1) should be connected to the ground of your circuit. You can connect J1:SHIELD to the ground net (Net 4) in your project. This helps with electromagnetic interference (EMI) protection and ensures a reliable connection.

what else do I need for the oscillator?

nico

@copilot what else do I need for the oscillator?

copilot

To properly connect the 12 MHz crystal oscillator (Y1) to the RP2040 (U1), you'll need two additional passive components: load capacitors. These capacitors are connected between each of the oscillator pins (P1 and P2) and ground. The recommended load capacitance can be found in the crystal oscillator's datasheet.

Here is what you should do:

Check the datasheet of the ABM3-12.000MHZ-D2Y-T crystal oscillator to find the recommended load capacitance.

Calculate the required load capacitor values using the formula: C_load_capacitor = (C_recommended_load - C_stray) / 2 where C_stray is the stray capacitance, which is typically between 2-5 pF.

Add two capacitors with the calculated values close to the crystal oscillator pins and connect them between the oscillator pins (P1, P2) and the ground.

Connect the crystal oscillator to the RP2040 microcontroller by connecting Y1:P1 to U1:XIN and Y1:P2 to U1:XOUT.

Remember to also connect the power and ground pins of the microcontroller to their respective power rails.

nico

How do I connect C1 and C2?

copilot

C1 and C2 are non-polarized capacitors, which means they can be connected in any orientation. To connect these capacitors to the circuit, follow these steps:

Determine the purpose of each capacitor in the circuit (e.g., decoupling, filtering, load capacitors for the crystal, etc.).

Identify the points in the circuit where the capacitors need to be connected based on their purpose.

For example, if C1 and C2 are intended to be used as decoupling capacitors for the RP2040 microcontroller (U1) and the AMS1117-3.3 voltage regulator (U2), you would connect them as follows:

Connect one end of C1 to the VDD pin of U1 (RP2040) and the other end to the nearest ground.

Connect one end of C2 to the VO pin of U2 (AMS1117-3.3) and the other end to the nearest ground.

Remember to select appropriate capacitor values based on the requirements of each component (check the datasheets for recommendations).

@copilot how do I connect this flash memory to the RP2040? I want to make sure I can boot from it.

copilot

To connect the W25Q128FVPIQ TR flash memory (U3) to the RP2040 microcontroller (U1) and enable booting from it, follow these steps:

Connect the SPI pins:
- Connect U3 ~CS (Chip Select) to U1 QSPI_CSN (Quad SPI Chip Select)
- Connect U3 CLK (Clock) to U1 QSPI_SCLK (Quad SPI Clock)
- Connect U3 D0 (Data 0) to U1 QSPI_SD0 (Quad SPI Data 0)
- Connect U3 D1 (Data 1) to U1 QSPI_SD1 (Quad SPI Data 1)
- Connect U3 WP (Write Protect) to U1 QSPI_SD2 (Quad SPI Data 2)
- Connect U3 HOLD (Hold) to U1 QSPI_SD3 (Quad SPI Data 3)

Connect power and ground:
- Connect U3 VCC to a 3.3V supply (you can use the output of U2, which is connected to U1 IOVDD)
- Connect U3 GND to the ground net (Net 3 in your project)

Add decoupling capacitors close to the VCC and GND pins of the flash memory. A 100nF capacitor is recommended. Connect the capacitor between VCC and GND.

After you've made these connections, the RP2040 should be able to boot from the connected flash memory. Make sure to program the flash with the appropriate bootloader and firmware for your application.

What about the EP (exposed pad) pin?

copilot

The EP (Exposed Pad) pin on the W25Q128FVPIQ TR flash memory is a thermal pad that helps dissipate heat generated by the chip during operation. To improve thermal performance, connect the EP pad to the ground plane on your PCB. This can be done by adding multiple vias under the pad to connect it to the ground plane. Make sure to follow the manufacturer's recommendations for pad size, number, and placement of vias in the PCB layout.

how do I connect the testen pin?

@copilot how do I connect the testen pin?

copilot

The TESTEN pin is used for enabling the test mode on the RP2040 microcontroller. In most cases, you don't need to use this pin. To keep the RP2040 in normal operation mode, you should connect the TESTEN pin to the ground (GND). This ensures that the test mode is disabled during regular use.

how do I connect the CC1 and CC2 pins? Do I need any pull resistors?

nico

@copilot how do I connect the CC1 and CC2 pins? Do I need any pull resistors?

copilot

Yes, you need pull-up resistors to properly configure the CC1 and CC2 pins of the USB-C receptacle (J1). These pins are used for detecting the cable orientation and establishing the power role. To connect them, follow these steps:

Add two 5.1kΩ resistors (you can use 0603 SMD package for consistency with other components in the project).

Connect one end of each resistor to the CC1 and CC2 pins of J1, respectively.

Connect the other end of both resistors to the 3.3V power supply (U2 VO).

This configuration will allow the USB-C connector to operate correctly in USB 2.0 mode and establish the proper power role for the device.

what decoupling capacitors do I need for the RP2040?

nico

@copilot what decoupling capacitors do I need for the RP2040?

copilot

For the RP2040, you should use decoupling capacitors to stabilize the power supply lines. According to the RP2040 datasheet, you should use the following decoupling capacitors:

A 1μF capacitor connected between VREG_VIN and GND.

A 1μF capacitor connected between VREG_VOUT and GND.

A 100nF capacitor connected between IOVDD and GND for each IOVDD pin (there are 5 IOVDD pins).

A 100nF capacitor connected between DVDD and GND.

A 100nF capacitor connected between ADC_AVDD and GND.

A 4.7μF capacitor connected between USB_VDD and GND (if using USB).

Place the decoupling capacitors as close as possible to the corresponding pins of the RP2040 to ensure optimal performance.

nico

@copilot, you mentioned two resistors needed for the USB data lines, what resistors do I need and how do I connect them?

copilot

Apologies for the confusion earlier. To properly terminate USB data lines, you'll need two 22 ohm resistors for USB 2.0 high-speed devices. You should connect them in series with the D+ and D- lines, between the microcontroller (U1) and the USB-C receptacle (J1).

Here's how to connect the resistors:

Add two 22 ohm resistors to your schematic (e.g., R1 and R2).

Connect R1 between J1's D+ pin and U1's USB_DP pin.

Connect R2 between J1's D- pin and U1's USB_DM pin.

These resistors help to match the impedance of the USB data lines and reduce reflections, improving signal integrity for high-speed data transmission.

To determine if the current setup can power the RP2040, I need to know how the components are connected in the circuit. Please provide information on the connections between the RP2040 (U1), AMS1117-3.3 (U2), and any other related components.

nico

how should I connect it to the Rp2040?

copilot

To power the RP2040 using the AMS1117-3.3 voltage regulator, you can follow these steps:

Connect the input voltage to the AMS1117-3.3:
- Connect the positive terminal of your power source (e.g., battery or power supply) to the "VI" pin (pin 1) of the AMS1117-3.3 (U2).
- Connect the negative terminal of your power source to the "GND" pin (pin 2) of the AMS1117-3.3 (U2).

Connect the output of the AMS1117-3.3 to the RP2040:
- Connect the "VO" pin (pin 4) of the AMS1117-3.3 (U2) to the "IOVDD" (3.3V) pin(s) of the RP2040 (U1).
- Connect the "GND" pin (pin 2) of the AMS1117-3.3 (U2) to the "GND" pin(s) of the RP2040 (U1).

Connect other required pins of the RP2040:
- Connect a 12 MHz crystal oscillator (Y1) between the "XIN" and "XOUT" pins of the RP2040 (U1) to provide a clock source.
- Connect the "RUN" pin to the "GND" through a 10kΩ resistor to enable the RP2040 (U1).

Make sure the input voltage provided to the AMS1117-3.3 is within its specified operating range (4.75V to 12V). The AMS1117-3.3 will output a regulated 3.3V, which is suitable for powering the RP2040.

how do I wire DVDD and ADC\_AVDD?

nico

@copilot how do I wire DVDD and ADC_AVDD?

copilot

To wire DVDD and ADC_AVDD on the RP2040 microcontroller (U1), follow these steps:

Connect DVDD (U1:DVDD) to a decoupling capacitor (C5) and then to the 3.3V power supply. Connect C5:P1 to U1:DVDD and C5:P2 to the 3.3V power supply (Net 1).

Connect ADC_AVDD (U1:ADC_AVDD) to a decoupling capacitor (C6) and then to the 3.3V power supply. Connect C6:P1 to U1:ADC_AVDD and C6:P2 to the 3.3V power supply (Net 1).

how do I connect the reset button to RUN pin?

nico

@copilot how do I connect the reset button to RUN pin?

copilot

To connect a reset button to the RUN pin of the RP2040 (U1), follow these steps:

Add a normally open (NO) tactile pushbutton to your schematic.

Connect one terminal of the pushbutton to the RUN pin (U1:RUN) of the RP2040.

Connect the other terminal of the pushbutton to the ground (GND) net.

When the button is pressed, it will pull the RUN pin to GND, causing a reset.

nico

Do I need a pull up resistor?

copilot

Yes, it's a good practice to add a pull-up resistor to the RUN pin of the RP2040 to ensure a stable voltage level when the reset button is not being pressed. Here's how to add a pull-up resistor:

Add a 10kΩ resistor (or any value between 4.7kΩ and 100kΩ) to your schematic.

Connect one terminal of the resistor to the RUN pin (U1:RUN) of the RP2040.

Connect the other terminal of the resistor to the 3.3V supply (U2:VO) or the IOVDD net.

This pull-up resistor will keep the RUN pin at a high level (3.3V) during normal operation and prevent false resets due to noise or voltage fluctuations. When the reset button is pressed, the RUN pin will be pulled to GND, causing a reset.
