Works as advertised. Frequency is easily adjustable and goes from about 25kHz to 35kHz,which is a bit narrower than advertised, but perfect for my needs. Wave shape is not perfect square, but is decent and will drive the power Mosfet(s) without issues. It has complimentary transistors that drive the low and high legs of the bridge, so It should be able to drive considerable power into mosfet/igbt transistors. Recommended.
very fast received I recommend seller
