| - | The 3.3V Relay Shield Kit allows you to build a shield that controls a relay with the Oak. Switch up to 24V DC or 120/240V AC wirelessly. The version for Oak uses a compatible 3.3 volt coil. The screw terminal has positions for both NC (normally closed) and NO (normally open). | + | The 3.3V Relay Shield Kit allows you to build a shield that controls a relay with the Oak. Switch up to 24V DC or 120/240V AC wirelessly. The version for Oak uses a compatible 3 volt coil (max 3.9 V, 110mA coil current). The screw terminal has positions for both NC (normally closed) and NO (normally open). |
| This is an unassembled kit and requires basic soldering. This is designed for use with the Digistump Oak development board, which is not included. | This is an unassembled kit and requires basic soldering.

| **Tip:** Inserting the headers into a breadboard and then placing the board on top can make this process easier. Unfortunately, most breadboards are one column too narrow for this to work for both the 6-pin and 3-pin headers. What works is to insert the 6-pin header in the edge column, then an extra 2-pin or or 1-pin header in the end row as shown; these are temporarily used to support the board, as is the 3-pin header placed at the diagonal corner. After soldering the 6-pin header (do not solder the 2-pin header!), remove the shield from the breadboard, then partially insert the pins with the third pin of the 3-pin header resting on the center slot. Solder the 3-pin header. | **Tip:** Inserting the headers into a breadboard and then placing the board on top can make this process easier.
