This evaluation board is on the 4 edges of the board, it features solder pads for all the interface ports provided by the laser driver. The solder pads can be used by clips or soldered with wires for connecting to external circuits. The power supply input is connected on the upper edge of the board. The incoming wires can be soldered on the pads, or clipped by alligator clips, or use the terminal block and tight the wires by the screws. In the upper middle of the board, there is an LED. When the controller works properly, it will be lit up. On the left side of the controller, there is a terminal block. It can be used for connecting wires going into the ports of the laser driver. On the lower side of the laser driver, there are 2 POTs (Potentiometers) for setting the lower and upper values of the set-point current. When the laser driver uses these POTs for setting the current values, push down the 2 switches below the POTs.
