This board is supplied with the Resonance Induction Coupler Kit 2. The one sold is slightly different than the one pictured. The picture is of the board provided with the Resonance Induction Coupler Kit 1 which includes a 9V connector and an additional black wire. We do not include the 9V connector or the extra black wire in this sale because the extra black wire is the same connection as the other black wire (the common ground). The 9V connector is parallel with the other red and black battery input wires on the left side of the board.
This gate driver board allows for an amplification of a weak signal from a frequency generator or similar signal. It can be used to drive mosfets as well.
