I ordered a small amplifier board on ebay. It's just a PCB with components, making a ready to go low powered audio amplifier, complete with a volume control.
It has three screw terminal blocks to attach the Power, Input and Output. It also has a 1/8" jack.
But here is the problem. Those screw blocks are labelled in Chinese. Using the actual chinese alphabet. If it was another language, I could convert the words online, but I cant enter chinese characters.
Fortunately, the power one says 12v with a + on one side, so I know that is the 12v source. But I hav no clue which of the other two are input or output, nor what that 1/8" plug is for.
I bought this from a US seller. You would think he would include a piece of paper showing what is what. The entire amp is mostly just one IC chip. Both the input and output go right to this chip, and there are parts in the way of the chip to try to read the chip numbers. (which likely would not match anything anyhow). [not to mention I cant see well enough to read chips anymore].
What is most weird, there is a LED on the board which says "LED" and the caps have numbers next to them (in english).
I plan to contact the seller to ask for an email containing the schematic or a photo showing what is what.....
This is the first time I have ever run across a PCB labeled in chinese...
