SparkFun Audio Amplifier Kit - STA540

The Sparkfun Audio Amplifier Kit - STA540 is a comprehensive package that allows you to build a fully functional, two-channel audio amplifier. The kit is centred around the STA540 power amplifier IC and includes a 6400BG heatsink to efficiently dissipate any heat generated during operation. The amplifier kit also features a standby switch, volume control and indicator LEDs for ease of use.

The STA540 in this kit is set up as a dual bridge amplifier, capable of delivering up to 2x 38W (4Ω at 18V). The power supplied to the kit directly powers the STA540 and should be within 8 to 22V. The kit arrives as a bag of parts, all of which need to be soldered to the PCB. However, all components are through-hole, making the process less complex than it might seem.

The Sparkfun Audio Amplifier Kit - STA540 can be used in a variety of applications. It's perfect for hobbyists and DIY enthusiasts looking to build their own audio equipment or for educational purposes, teaching electronics and soldering techniques. The product also offers a unique opportunity to understand and experience the workings of a dual bridge amplifier.

The kit includes the STA540 Audio Amplifier Kit PCB, STA540 Dual/Quad Power Amplifier, 6400BG Heatsink, LM358 Op Amp, three Basic Red LEDs, an SPDT Mini Power Switch, a variety of resistors and capacitors, 2-Pin Screw Terminals, Nylon Round Female Standoffs, Phillips Screws with 4-40 Thread, and a #4-40 Hex Nut.

The product also comes with a schematic, Eagle Files, assembly instructions and GitHub resources for your convenience and ease of assembly. With the Sparkfun Audio Amplifier Kit - STA540, you get a comprehensive package that offers both a learning opportunity and a practical application.
