SparkFun Beefcake Relay Control Kit (Ver. 2.0)

The SparkFun Beefcake Relay Control Kit (Ver. 2.0) is a powerful tool for your 5V system. This robust relay board can handle 10A on the NC contacts and 20A on the NO contacts at 220VAC. The kit includes all the components required to control high-power loads, with only minimal assembly needed.

The main component of the board is a sealed, SPDT 20A/10A Relay. The relay is regulated by 5V logic via a transistor, and an LED indicates when the relay is closed. This kit is provided as through-hole parts, offering an excellent opportunity for soldering practice. The inclusion of screw terminal connectors on both sides of the board ensures easy integration into your project.

The board features robust traces connecting the relay to the load pins. However, the 3-pin terminals have a maximum rating of 15A. For larger loads, direct soldering to the board is necessary. As with all high current and voltage applications, safety is paramount. Always use your judgement when determining the load to put on a board. In open airflow, the PCB can handle the full 20A for short periods, but heat can accumulate in an enclosed area.

Note: This board is designed for individuals with experience and a good understanding of electricity. If you're not comfortable with soldering or handling high voltage, consider the IoT Power Relay. This is fully enclosed, providing enhanced safety.

The SparkFun Beefcake Relay Control Kit (Ver. 2.0) has a number of features:

• Voltage Rating: 220VAC/28VDC
• VCC requirements: 4-6V, 150mA capable
• SPDT pins exposed (Form C)
• 14 AWG screw terminals for relay connections
• 10 AWG solder lugs for relay connections
• Included flyback diode
• Included Zener recovery diode (decreases turn-off time)
• Heavy 2 oz. (approx. 57g) copper on PCB
