Jól használható termék. Köszönöm!
Nice small oscillator. 4 frquency ranges. Hard to control dutycycle in th 2 higest ranges. Especially the higest, almost impossible. Wave form i higest range is far from sqare. Very usefull in lower ranges.

All products came in quick and sound...
Received after 50 days and seems in order. I need to check how it works
great seller will buy again
Everything has arrived as I expected. The delivery was very fast. Everything was very good - as described.
Easy to use, compact and useful. No need any external controller, just power supply. Can be used to control your H-bridges and drive your DC motors.
