1. VCC: Conecta este pin a una fuente de alimentación de 3.7-4.2V. El módulo SIM800L requiere una fuente de alimentación que pueda entregar hasta 2A durante las ráfagas de transmisión. No conectes este pin directamente a un pin de 5V del Arduino ya que podría dañar el módulo.
2. GND: Conecta este pin al pin de tierra (GND) en el Arduino.
3. TXD: Este es el pin de transmisión del SIM800L. Conéctalo al pin de recepción (RX) del Arduino, que es el pin digital 0.
4. RXD: Este es el pin de recepción del SIM800L. Conéctalo al pin de transmisión (TX) del Arduino, que es el pin digital 1.
5. RST (Reset): Este pin puede ser conectado a un pin digital en el Arduino (como el pin digital 7), permitiéndote resetear el módulo SIM800L programáticamente.

1. Accessing Flux: The first step is to navigate to the Flux.ai website and log in or sign up if you haven't already.
2. Starting Your First Project: Once logged in, you can start a new project by selecting the option to create a new schematic or PCB layout. This is your workspace where you will design your circuit or PCB.
3. Placing Components:
   • In the schematic editor, use the library of components to find the parts you need for your design.
   • Drag and drop these components onto your canvas.
4. Making Connections:
   • To connect components in your schematic, use the wire tool to draw connections between the appropriate pins of different components.
   • Pay attention to the net names to ensure that connections meant to carry the same signal are properly linked.
5. Assigning Footprints:
   • After completing your schematic, you'll need to assign physical footprints to your components for the PCB layout phase.
   • This step is crucial for ensuring that the physical dimensions and pin layouts match the components you plan to use.
6. Laying Out Your PCB:
   • Switch to the PCB layout view.
   • Arrange the components on your board, considering optimal placement for signal integrity, power distribution, and mechanical constraints.
   • Use the trace routing tools to connect the pins according to your schematic.
7. Running Checks:
   • Flux offers various tools to check your design for common errors or issues, such as unconnected nets or overlapping components.
   • Use these verification tools to refine your design.
8. Exporting Your Design:
   • Once you're satisfied with your design, you can export the necessary files for manufacturing, such as Gerber files for the PCB and a bill of materials (BOM) for the components.

• Help and Tutorials: In-depth tutorials about how to use Flux, including your first project and specific features[1].
• YouTube: Video example projects and tutorials all in Flux[2].
• Slack Community: Join the community for direct support from the Flux team and other users[3].

1. Choosing a GPS Module:
   • A commonly used GPS module is the NEO-6M or NEO-7M GPS module. These modules usually communicate over UART and are widely supported by various microcontroller platforms.
   • Ensure the GPS module operates at compatible logic levels with the SIM800L (typically 3.3V).
2. Wiring the GPS Module to the M5Stack Platform:
   • Power Connections: Connect the GPS module's VCC and GND pins to a 3.3V power source and ground, respectively. You can use the VBAT and GND pins for this purpose.
     • Connect GPS Module VCC to VBAT.
     • Connect GPS Module GND to any GND.
   • Serial Communication: Connect the GPS module's TX (transmit) pin to a suitable RX (receive) pin on the M5Stack platform and the RX pin to a TX pin. Assuming GPIO1($P:GPIO1$) and GPIO2($P:GPIO2$) or other available GPIO pins can be configured as UART RX and TX respectively,
     • Connect GPS Module TX to $P:GPIO1$ (or another suitable RX pin).
     • Connect GPS Module RX to $P:GPIO2$ (or another suitable TX pin).
3. Software Configuration:
   • Initialize UART: In your code, initialize a UART instance using the chosen RX and TX pins.
   • Read GPS Data: Write or use existing library code to read data from the GPS module. GPS modules typically send data in NMEA (National Marine Electronics Association) format, which you'll need to parse to extract information like latitude, longitude, time, etc.
4. Integration:
   • If you plan to send GPS data over GSM using the SIM800L, you'll need to format the read GPS data into a suitable format (e.g., a JSON string or a simple comma-separated string) and send it as an SMS or over a data connection using the AT commands supported by the SIM800L.

• GPIO1 and GPIO2 pins are available for use and compatible for UART communication. Adjust pin numbers based on actual availability and configuration in your project.
• The M5Stack Platform and the GPS module operate on compatible voltage levels. If not, level shifters might be required.
