How to Use Adafruit Terminal Breakout FeatherWing: Examples, Pinouts, and Specs

The Adafruit Terminal Breakout FeatherWing is an essential accessory for developers and hobbyists who use Adafruit Feather boards. This add-on board simplifies the process of connecting wires to a Feather board by providing screw terminal blocks. It is ideal for quick prototyping and development projects where a sturdy and reusable connection is necessary. The Terminal Breakout FeatherWing is compatible with the entire Feather line and is particularly useful in applications where frequent re-wiring is required, such as in educational settings, rapid prototyping, or test fixtures.

• Compatibility: Designed to work with all Feather boards
• Terminal Blocks: Screw terminals for all Feather pins
• Dimensions: 50.8mm x 22.9mm x 1.6mm / 2.0" x 0.9" x 0.06"
• Weight: 5.2g / 0.2oz

1. Align the Terminal Breakout FeatherWing with the headers on your Feather board.
2. Carefully press down to mate the connectors. Ensure all pins are aligned correctly.
3. Use a soldering iron to solder the headers to the Feather board for a permanent connection.
4. Once soldered, you can use the screw terminals to easily connect and disconnect wires.

• Wire Gauge: Ensure the wires used are compatible with the screw terminal block specifications.
• Secure Connections: Always tighten the screws on the terminal blocks to prevent loose connections.
• Power Ratings: Do not exceed the recommended voltage and current ratings of the Feather board.
• Short Circuits: Be cautious to avoid creating short circuits when connecting wires to the terminal blocks.

// Example code to demonstrate how to use the Terminal Breakout FeatherWing
// with an Arduino UNO. This example will blink an LED connected to pin 13.

void setup() {
  pinMode(13, OUTPUT); // Initialize pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for a second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for a second
}

• Loose Connections: If your circuit is not working as expected, check all terminal screws to ensure they are tightened properly.
• Incorrect Wiring: Double-check the wiring against the circuit diagram to ensure all connections are correct.
• Soldering Quality: Poor soldering can lead to unreliable connections. Inspect solder joints for cold solder or bridges.

Q: Can I use the Terminal Breakout FeatherWing with any Feather board? A: Yes, the Terminal Breakout FeatherWing is designed to be compatible with all Feather boards.

Q: Do I need to solder the Terminal Breakout FeatherWing to the Feather board? A: Yes, for a secure and reliable connection, soldering is recommended.

Q: How much current can the terminal blocks handle? A: The current handling capability will depend on the specifications of the Feather board used. Always refer to the Feather board's documentation for power ratings.

Q: Can I use the Terminal Breakout FeatherWing for high-frequency applications? A: The Terminal Breakout FeatherWing is suitable for most prototyping applications, but for high-frequency signals, ensure that the wiring and connections are appropriate for the frequency range.
