15W Stereo Amplifier Case
thingiverse
This is a project to build a 15W audio amplifier board that can be found on eBay, AliExpress, and other online marketplaces such as https://www.aliexpress.com/store/product/Hot-Sale-1pc-TDA7297-Version-B-2-15W-Digital-For-Audio-Amplifier-Board-Dual-Channel-AC/1959068_32666077241.html?spm=2114.12010615.0.0.7a894502EdjFEn . I use this amplifier for an Asus Tinker Board. You will also need a mini toggle switch, a barrel power jack, and a 1/8" stereo jack, along with some 22 gauge wire. The hole for the power jack is 8.25 mm, while the hole for the audio jack is 6.25 mm. The board is held in place by one 8 mm M3 screw on the front. Since the screws in the back are hard to reach, using 20 mm M3 screws helps, and then with tweezers it's possible to put the nut on top of the screw. The heads of the screws are located on the bottom of the case. The main webpage for this project is http://www.ctheroux.com/15w-stereo-amplifier-case/.
