Product name: Rocker module (dual-axis button rocker) Product size: 34.0mm x 26.0mm x 32.0mm (length x width x height) The dual-axis button rocker sensor module is made of PS2 rocker potentiometer, with (X, Y) 2-axis analog output and (Z) 1-channel button digital output. With the sensor expansion board, you can create interactive projects such as remote controls. In addition, to more conveniently support standard interfaces such as expansion boards, this product is designed to lead out the circuits of the X, Y, and Z axes separately. Users can use a 3-pin dedicated cable to connect directly to the expansion board for use.
