copilot

The typical operating voltage range for the

\text{SIM800L}

(designator U3) is between 3.4V and 4.4V, with an optimal voltage of 4.0V. It's essential to ensure that VCC (pin 2) on the

\text{SIM800L}

module is provided with a stable voltage within this range to ensure proper operation.

Sure thing! Let's address the changes needed in the project to switch from Seeed Studio XIAO RP2040 to

XIAO \text{nRF52840 BLE Sense}

Changes to Schematic:

Update the microcontroller U2 to the new Seeed XIAO nRF52840 BLE Sense. Pin mappings will need adjustment in the schematic to match the new microcontroller pins.

Connections:

Here's how you can map the connections from the original microcontroller to the new one. Make sure all your connections align with the new pinout of the Seeed XIAO nRF52840 BLE Sense.

Power and Ground
- Connect U2:12 (3V3) to your 3.3V power source.
- Connect U2:13 (GND) to your ground.

OLED Display
- You might need to connect the OLED display via I2C:
  - Connect U2:5 $P0.04\_SDA\_A4\_D4$ to $OLED:SDA$ .
  - Connect U2:6 $P0.05\_SCL\_A5\_D5$ to $OLED:SCL$ .

UART WiFi Module:
- Connect U2:7 $P1.11\_TX\_D6$ to $UART \text{WiFi Module:RX}$ .
- Connect U2:8 $D7\_RX\_P1.12$ to $UART \text{WiFi Module:TX}$ .

UART SIM800L Cellular Module:
- Connect U2:7 $P1.11\_TX\_D6$ to $SIM800L:RX$ .
- Connect U2:8 $D7\_RX\_P1.12$ to $SIM800L:TX$ .

Normally Open Float Switch:
- This could be connected to any of the GPIOs; for instance:
- Connect one end of the float switch to a GPIO pin such as U2:1 $P0.02\_A0\_D0$ .
- Connect the other end to GND.

Verification:

Ensure that all other connections are correctly mapped to the new microcontroller's pins.

Double-check the power supply and ground connections to maintain the integrity of the circuit.

Summary of Connections:

Power: Connect U2:12 (3V3) to $PowerNet1:P1$ .

Ground: Connect U2:13 (GND) to GND.

OLED Display: Connect U2:5 $P0.04\_SDA\_A4\_D4$ to $OLED:SDA$ and U2:6 $P0.05\_SCL\_A5\_D5$ to $OLED:SCL$ .

UART WiFi Module: Connect U2:7 $P1.11\_TX\_D6$ to $UART \text{WiFi Module:RX}$ and U2:8 $D7\_RX\_P1.12$ to $UART \text{WiFi Module:TX}$ .

UART SIM800L: Connect U2:7 $P1.11\_TX\_D6$ to $SIM800L:RX$ and U2:8 $D7\_RX\_P1.12$ to $SIM800L:TX$ .

Float Switch: Connect U2:1 $P0.02\_A0\_D0$ to one end of Float Switch; Connect other end to GND.

Would you like to proceed with this or do you have any other components you'd like to adjust?

This project is a vessel monitoring system built using Seeed Studio Xiao Sense, Xiao Expansion Board with OLED, a UART WiFi module, a normally open float switch, and a UART SIM800L cellular module. The system displays a 30-second countdown on the OLED screen, calibrates the IMU sensor, converts to Euler angles, and stores these values for comparison with future readings. It also sets up the WiFi module as an access point to configure the vessel's name, contact numbers, and angle thresholds for list and trim notifications. Reports are sent at specified times via the cellular module. @copilot

Great! Let’s break down your system and outline the necessary connections given the components you’ve listed. Here are some connections and assumptions based on your project requirements:

Components and Connections

Seeed Studio Xiao Sense RP2040 (U1 - $102010428$ )
- This board includes an IMU sensor and is essential for the IMU calibration and angle conversion.

Xiao Expansion Board with OLED
- Provides OLED display and additional connectors for peripherals.

UART WiFi Module
- Will be configured as an access point for configuration.

Normally Open Float Switch
- Detects the presence of water.

UART SIM800L Cellular Module
- Used for sending reports via cellular network.

Design Assumptions and Connections Power and Ground

Connect $U1:5V$ to $PowerNet1:P1$ to provide 5V to the Xiao power pin.

Connect $U1:GND$ to GND (Ensure this GND is tied to the ground plane of the circuit).

OLED Display on Xiao Expansion Board

Assuming it’s directly interfaced with Seeed Studio Xiao Sense RP2040, you won't need to do additional connections here.

UART WiFi Module Connections

Assuming it uses standard UART interface for communication:
- Connect $U1:P0\_TX\_D6$ to WiFi module:RX
- Connect $U1:D7\_CSn\_P1\_RX$ to WiFi module:TX
- Ensure the WiFi module's power and ground are properly connected.

Float Switch

Connect Float Switch: Signal Line to an available GPIO pin on $U1$ (e.g., $U1:P26\_A0\_D0$ )

Connect other Float Switch: Vcc Line to the appropriate voltage (e.g., 3V3 or 5V depending on your switch specifications).

Ground the float switch if necessary.

SIM800L Module Connections

Assuming it also uses standard UART:
- Connect $U1:P0\_TX\_D6$ to SIM800L:RX
- Connect $U1:D7\_CSn\_P1\_RX$ to SIM800L:TX
- Ensure the SIM800L module's power and ground are properly connected.

Next Steps in Design

IMU Sensor Connection:
- The IMU sensor is embedded in the Xiao Sense RP2040. You will access and calibrate it through the Xiao Sense’s firmware and libraries.

WiFi Access Point Configuration:
- Program the WiFi module to operate in an access point mode and handle the necessary initial configurations for the vessel’s name, contact numbers, and angle thresholds.

Cellular Module Communication:
- Implement code to send periodic reports via the SIM800L module using AT commands or relevant libraries.

Example Initial Schematic Connections

Power and Ground
- Connect $U1:5V$ to $PowerNet1:P1$ .
- Connect $U1:GND$ to GND.

WiFi Module
- Connect $U1:P0\_TX\_D6$ to WiFi RX.
- Connect WiFi TX to $U1:D7\_CSn\_P1\_RX$ .

Float Switch
- Connect Float Switch signal line to $U1:P26\_A0\_D0$ .
- Connect Float Switch Vcc line to the desired voltage level.

SIM800L Cellular Module
- Connect $U1:P0\_TX\_D6$ to SIM800L:RX.
- Connect SIM800L:TX to $U1:D7\_CSn\_P1\_RX$ .

Additional Considerations

Ensure the proper libraries are in use for the RP2040 board, specifically for the IMU sensor, OLED display, WiFi configuration, and SIM800L communication.

Feel free to ask if you need more specific details regarding configurations or alternative component choices. Happy designing!
