@copilot recommend a replacement for J1.

3mo

I see that the current part for

J1

is a USB Type-C connector, MPN: TYPE-C-31-M-12. While I don't have access to a live database to give you specific alternatives, I can suggest considering connectors with similar specifications from other manufacturers. Here are some general guidelines and manufacturers to consider:

Check the footprint compatibility: Ensure the replacement has a compatible mounting style and footprint.

Current and Voltage Ratings: Make sure the replacement can handle similar or better electrical specifications.

Manufacturers to Consider:
- Amphenol
- TE Connectivity
- Molex
- Hirose Electric
- JST

Specifications:
- Look for a USB Type-C connector supporting similar or better data rates and power delivery.
- Ensure mechanical fitment matches your board design.

You may want to browse distributor websites like Digi-Key, Mouser, or LCSC for specific part numbers and availability. If you tell me more about your specific requirements, I can help narrow down the options further!

10mo

copilot

For programming the ESP32-C3-MINI-1 module in your project, you'll typically need to connect several important pins to your programmer or USB-to-Serial converter. Based on standard practices for programming ESP32 modules, the key pins involved in programming are:

IO0 (GPIO0): This pin is used to enter the bootloader mode. It needs to be pulled LOW during reset for the module to enter programming mode.

RXD0 and TXD0: These are the UART pins you'll use for serial communication. RXD0 on your ESP32 module should be connected to TX on your USB-to-Serial converter, and TXD0 to RX.

EN (Enable): Sometimes called RST (Reset), this pin is used to reset the module. Typically, it's connected to a momentary button or can be controlled by the programmer to reset the ESP32 as part of the programming process.

GND (Ground): A common ground between the ESP32 module and your USB-to-Serial adapter or programmer is necessary.

3V3 (3.3V Power): The ESP32 operates at 3.3V, so ensure that it's powered accordingly during programming.

Given these requirements, please proceed with the following connections:

Connect U1:IO0 to your programmer's GPIO to pull it LOW during reset (to enter programming mode).

Connect U1:RXD0 to the TX pin of your USB-to-Serial converter.

Connect U1:TXD0 to the RX pin of your USB-to-Serial converter.

Connect at least one U1:GND pin to your converter's GND pin.

Connect U1:3V3 to a 3.3V supply on your converter or to an external 3.3V power source as required.

Make sure your ESP32 module is properly powered (3.3V) and all devices share a common ground to ensure successful programming. If you're using a USB-to-Serial adapter, double-check the voltage levels to ensure it operates at 3.3V logic to match the ESP32's levels.

Hey, I’m Copilot, your AI design assistant. I can help you brainstorm ideas, debug problems, research components, and even make wiring connections for you. Ask me questions like:

@copilot I'm designing a PCB for a medical device that measures heart rate and temperature. Can you give me the list of components I will need?

@copilot How would I connect these parts to make the LED flash at 1kHz?

@copilot can you choose 4 digital pins on the ATMega328P-AU that I have here to use as GPIO given that I am already using some pins for reset, the external clock, UART, and I2C.

Chat with me by tagging @copilot on comments or in the chat.

isnt io9 floating when you dont press the button?

4mo

copilot

Yes, it appears that IO9 would be floating when the button isn't pressed. To avoid this floating state, you need a pull-up or pull-down resistor. Given that IO9 is typically used for boot strapping (boot mode selection), it is a good practice to use a pull-up resistor.

In your configuration, IO9 is connected as follows:

Connections

ESP_BOOT: $(P1)$ to U1: $(IO9)$

SW1: $(\sim3)$ to ESP_BOOT: $(P1)$

SW1: $(\sim1)$ to ESP_BOOT: $(P1)$

To prevent IO9 from floating, you can add a pull-up resistor (typically 10kΩ) to 3.3V:

Suggested Connection

Connect a 10kΩ resistor between IO9 and the 3.3V net (Net 11):
- R11 (10kΩ resistor): Connect $(P1)$ to 3V3: $(P1)$ and $(P2)$ to U1: $(IO9)$

You can update the schematic as follows:

Add a new resistor R11 between IO9 and the 3.3V net.

Let me know if you need any further adjustments or details!

what linear regulators are between the 5V pin and the ESP32 chip?

what linear regulators are between the 5V pin and the ESP32 chip?

3mo

copilot

In your schematic, there is no linear regulator between the 5V pin and the ESP32-C3-MINI-1 chip. Instead, you have a switching regulator:

Switching Regulator

IC1: TPS62130RGTR

The TPS62130RGTR is a step-down switching regulator that converts the input from the 5V supply to a lower regulated output voltage (typically 3.3V) for powering the ESP32 module.

Connections

IC1:$PVIN$ and $AVIN$ are connected to the 5V net.

IC1:$VOS$ outputs to the 3.3V net, which powers the U1 chip through U1:$3V3$.

The setup uses the TPS62130RGTR to efficiently convert 5V to 3.3V, reducing power loss compared to a linear regulator.

If you have any additional questions or need further elaboration, feel free to ask!

babok23

So if my ESP32 was to fail, I was powering it off the 5V pin not the USB input this is for an ESP32-C3-DEVKITM-1 for context. Would it be most likely that the TPS62130RGTR failed as something inside the chip has short circuited whenever we plug it in the chip get really hot and that is all the signs of a short circuit

3mo

copilot

If your ESP32-C3-DEVKITM-1 module is getting excessively hot when powered from the 5V pin and not via USB, there could indeed be a few potential causes:

Possible Causes

Faulty TPS62130RGTR: If the TPS62130RGTR has failed and is shorted internally, it could draw excessive current and get very hot.

Short Circuit on the 3.3V Rail: If there is a short circuit downstream (e.g., on the 3.3V rail exposed to other components), this could draw excessive current through the TPS62130RGTR.

Fault in the ESP32 Module: A fault within the ESP32 chip itself could cause excessive current draw if an internal short has developed.

Incorrect Power Wiring: If the wiring or net connections are incorrect, it might lead to excessive current flow.

Diagnostic Steps

Check for Shorts: Use a multimeter to check if there is a short circuit between the 3.3V and GND rails.

Inspect Component Connections: Visually inspect solder joints and traces for any obvious shorts or solder bridges.

Measure Voltages: Measure the voltage output of the TPS62130RGTR to see if it is within the expected range (roughly $3.3V$).

Thermal Inspection: Carefully determine which components are heating up and in what order. Heat can often indicate the source of the fault.

Isolation Test: If possible, isolate the ESP32 module and power the TPS62130RGTR without it to see if the overheating persists.

If the TPS62130RGTR is indeed the component failing, replacing it might resolve the issue. However, the source of the short must first be identified to prevent recurrence.

If you're still unsure or need further analysis, sharing additional details or test results can help narrow down the cause. Let me know how you'd like to proceed!
