Julian Y. ★★★★★

Hooked this up to a 9V battery for a quick bench test and the square wave was perfectly clean right out of the box. The wide power supply range is great since I can use whatever battery pack I have lying around.

Thomas K. ★★★★★

I needed a clean square wave for testing, and this little module delivers exactly that—the wide 4.5-12V input range means I can run it off leftover batteries. The NE555 timing is rock steady, and it fired up instantly on first power.

Zoe ★★★★★

Powered it with a 9V battery and got a clean square wave right away; the wide 4.5–12V range made it easy to test. The frequency knob is smooth enough for tuning, though it takes a second to get the exact setting you want. Solid little module for the price.
