    These relay boards are very good value for money, well-rated for most applications and easy to connect. Just one word of warning - the output screw- terminals are prone to stripping - DO NOT OVER-TIGHTEN. These boards are used on the outputs of my Christmas light display controller (Geekcreit Mega 2560).

    since the product is not well protected during transport, some connection pins were slightly bent. This could be restored rather easily. Note that the input has to be 0 -5V level. at 3,3V, not enough current passes trough the opto-couplers. Connection with a 3,3V signal level is possible but Vcc has to be 5V and not 3,3V

    The board offers 8 ports for isolated SPDT load switching rated at 10A each. LED and relays can be sourced seperately. Coils are logic controlled with isolation as well.

    All channels tested positive. Appearance is not the best (it does not look like if you have an original Arduino board for example). But this is not an issue. I assume the quality is good because it works well. Let's see how reliable it will be.

    Excellent value for price. (I would prefer a version with direct drive and without LEDs so energy consumption is less.)
