WeIO is a versatile IoT (Internet of Things) development platform designed to simplify the creation and management of connected devices. It features a user-friendly web-based interface, supports multiple programming languages (such as Python and JavaScript), and offers built-in Wi-Fi connectivity for seamless integration into IoT ecosystems. With its focus on rapid prototyping and deployment, WeIO is an excellent choice for developers, hobbyists, and engineers looking to build smart devices and IoT applications.

• Smart home automation systems
• Environmental monitoring and data logging
• Wearable devices and health monitoring
• Industrial IoT applications
• Prototyping connected consumer electronics
• Educational projects and IoT learning platforms

1. Powering the WeIO Board:

   • Connect the board to a 5V USB power source or a compatible 3.3V power supply.
   • Ensure the power source provides sufficient current (~200 mA) for stable operation.

2. Connecting to Wi-Fi:

   • Access the WeIO web interface by connecting to the board's default Wi-Fi network.
   • Open a web browser and navigate to the default IP address (e.g., 192.168.1.1).
   • Configure the board to connect to your local Wi-Fi network.

3. Programming the Board:

   • Use the web-based IDE provided by WeIO to write and upload code.
   • Alternatively, you can use Python or JavaScript to program the board via the IDE.

4. Interfacing with Sensors and Actuators:

   • Use the GPIO pins to connect sensors (e.g., temperature, humidity) or actuators (e.g., motors, LEDs).
   • Refer to the pin configuration table to identify the appropriate pins for your application.

5. Deploying IoT Applications:

   • Use the built-in libraries and APIs to send data to cloud platforms or control devices remotely.
   • Leverage the board's support for HTTP, MQTT, or WebSocket protocols for communication.

• Voltage Levels: Ensure all connected peripherals operate at 3.3V logic levels to avoid damaging the board.
• Wi-Fi Signal Strength: Place the board in an area with a strong Wi-Fi signal for reliable connectivity.
• Heat Management: Avoid placing the board in enclosed spaces without ventilation, as it may generate heat during operation.
• Firmware Updates: Regularly check for firmware updates to ensure compatibility with the latest features and bug fixes.

Although WeIO is a standalone platform, it can communicate with an Arduino UNO via UART or I2C. Below is an example of using UART communication:

void setup() {
  Serial.begin(9600); // Initialize UART communication at 9600 baud
}

void loop() {
  Serial.println("Hello from Arduino!"); // Send a message to WeIO
  delay(1000); // Wait for 1 second
}

import serial
import time

arduino = serial.Serial('/dev/ttyUSB0', 9600, timeout=1) time.sleep(2) # Allow time for the connection to initialize

while True: # Read data from Arduino data = arduino.readline().decode('utf-8').strip() if data: print(f"Received from Arduino: {data}") # Print received message time.sleep(1) # Wait for 1 second

1. The board does not power on:

   • Ensure the USB cable or power supply is functioning correctly.
   • Verify that the power source provides sufficient current (at least 200 mA).

2. Unable to connect to the WeIO Wi-Fi network:

   • Check if the board is powered on and broadcasting its Wi-Fi SSID.
   • Reset the board to factory settings if the default Wi-Fi network is not visible.

3. Code does not execute as expected:

   • Verify that the correct pins are used for connecting peripherals.
   • Check for syntax errors or incorrect logic in the code.

4. Wi-Fi connection drops frequently:

   • Ensure the board is within range of the Wi-Fi router.
   • Reduce interference from other wireless devices operating on the same frequency.

• Can I use external libraries with WeIO?
  Yes, WeIO supports external Python and JavaScript libraries. You can upload them via the web-based IDE.

• What is the maximum range of the built-in Wi-Fi?
  The range depends on environmental factors but typically extends up to 30 meters indoors.

• Can I power the board using batteries?
  Yes, you can use a 3.3V battery pack or a 5V USB power bank to power the board.

• Is WeIO compatible with cloud platforms?
  Yes, WeIO supports integration with popular cloud platforms using HTTP, MQTT, or WebSocket protocols.
