Pcb covox amp
About the Pcb covox amp
Pcb covox amp is an open source PCB design by yeokm1, published on GitHub under the MIT license. It is a 2-layer board measuring 78 × 56 mm, with 39 components from 16 distinct parts.
Other key parts include the LM386. By type, the board carries 20 resistors, 12 capacitors, 2 connectors, 1 IC and 1 diode.
It belongs with the audio designs in this gallery.
From the project
A tiny sound card based on the Covox Speech Thing design which includes an LM386 amplifier.
Due to copyright problems in the music used, this video can only be viewed on a PC. It is blocked on mobile devices and other platforms.
The picture is of the Rev 2 version with the bug in the limited parallel port grounding. This has been corrected in the Rev 3 gerber but not fabricated.
As reported in this issue, there is a mistake in components R2 and C6. As I'm not currently using this project, I'll not be correcting this error.
