How to Use RedBoard Artemis Nano: Examples, Pinouts, and Specs

The RedBoard Artemis Nano is a versatile, Arduino-compatible development board that integrates the powerful Artemis module from SparkFun. This compact board is designed for a wide range of applications, from wearable devices to IoT projects, thanks to its built-in Bluetooth Low Energy (BLE) and USB-C connectivity. Its small form factor makes it ideal for projects where space is at a premium.

1. Powering the Board: Connect the USB-C cable to the board and a power source (such as a computer or USB charger) to power the RedBoard Artemis Nano.
2. Connecting I/O Pins: Use jumper wires to connect the I/O pins to other components, such as sensors, actuators, or breadboards.
3. Programming the Board: Use the Arduino IDE or other compatible software to write and upload sketches to the board via the USB-C connection.

• Always ensure that the power supply is within the specified range to prevent damage.
• When connecting external components, make sure they are compatible with the board's operating voltage (3.3V).
• To avoid short circuits, double-check wiring before powering up the board.
• Use the onboard Qwiic connector for easy I2C communication with compatible devices.
• For BLE functionality, ensure that the appropriate libraries and board definitions are installed in your development environment.

• Board Not Recognized: Ensure that the USB-C cable is properly connected and that the correct drivers are installed on your computer.
• Sketch Upload Failure: Check the selected board and port in your development environment. Make sure the correct bootloader is used.
• I/O Pin Malfunction: Verify that the pin is configured correctly in your sketch and that there are no shorts or incorrect connections in your circuit.

• If the board is not recognized, try a different USB port or cable and restart your development environment.
• For upload issues, double-check the board settings and attempt to upload with the bootloader mode activated.
• If an I/O pin is not working as expected, test it with a simple sketch to rule out software issues.

Here's a simple example of how to blink an LED connected to pin D2 of the RedBoard Artemis Nano using the Arduino IDE:

// Define the LED pin
const int ledPin = 2;

void setup() {
  // Initialize the LED pin as an output
  pinMode(ledPin, OUTPUT);
}

void loop() {
  // Turn the LED on
  digitalWrite(ledPin, HIGH);
  // Wait for a second
  delay(1000);
  // Turn the LED off
  digitalWrite(ledPin, LOW);
  // Wait for a second
  delay(1000);
}

Remember to select the appropriate board from the Arduino IDE's board manager before uploading the sketch. This code will toggle the LED on and off, creating a blinking effect.
