### ⭐ Works until it doesn't

Both worked until pot was turned. Then quit working. Pot finally came apart. Do not waste your time.

### ⭐⭐⭐⭐⭐ Tiny
*by K***R on February 9, 2023*

Have used one of the two, with a 9V battery, 1/4 W speaker and a piezo mic - works great. Haven't tested the other. Pin hole spacing fits standard pin headers, so easy connections after soldering three 2-pin headers to the board.
