Once this kit is completed you have a fully functional, two-channel audio amplifier, complete with a standby switch, volume control and indicator LEDs. The kit also includes a 6400BG heatsink for the STA540 to dissipate any damaging heat.<\/p>\n<p>In this kit, the STA540 is configured as a dual bridge amplifier capable of delivering up to 2x 38W (4O at 18V). Power supplied to the kit directly powers the STA540 and should be within 8 to 22V.<\/p>\n<p>This kit comes as a bag of parts, you\u2019ll need to solder everything to the PCB. All components are through-hole, so it shouldn\u2019t be too difficult; but this kit is a bit more complex than our other through-hole kits.<\/p>\n<p><strong>Kit Includes:<\/strong><\/p>\n<ul>\n<li>1 x STA540 Audio Amplifier Kit PCB<\/li>\n<li>1 x STA540 Dual\/Quad Power Amplifier<\/li>\n<li>1 x 6400BG Heatsink<\/li>\n<li>1 x LM358 Op Amp<\/li>\n<li>3 x LED &#8211; Basic Red<\/li>\n<li>1 x SPDT Mini Power Switch<\/li>\n<li>Resistors:\n<ol>    5 x 10K Ohm<\/ol>\n<ol>    3 x 1.0K Ohm<\/ol>\n<ol>    2 x 47k Ohm<\/ol>\n<ol>    2 x 100k Ohm<\/ol>\n<ol>    2 x 10k Giant Trimpot<\/ol>\n<\/li>\n<li>Capacitors:\n<ol>    1 x 0.1uF-50V-20%<\/ol>\n<ol>    1 x 100uF &#8211; 25V<\/ol>\n<ol>    4 x 0.47uF-25V<\/ol>\n<ol>    2 x 10pF &#8211; 200V &#8211; 5%<\/ol>\n<ol>    3 x 1uF &#8211; 50V &#8211; -20,+80%<\/ol>\n<ol>    1 x 1000uF\/25V<\/ol>\n<\/li>\n<li>5 x 2-Pin Screw Terminal &#8211; 3.5mm<\/li>\n<li>4 x Nylon Round Female Standoff<\/li>\n<li>5 x Phillips Screw with 4-40 Thread<\/li>\n<li>1 x #4-40 Hex Nut<\/li>\n<\/ul>\n<p><strong>Don Luc<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SparkFun: KIT-09612 Description: This is a stereo amplifier kit designed to make use of the STA540 power amplifier IC.
