Solution:

Description: This document shows the difference between the phased-out PCL-720 and the new PCL-720+. Solution: Actually the PCL-720 and PCL-720+ are compatible with each other. The only difference between these two versions is the breadboard area. The dimension of breadboard on PCL-720 is 30 ×18. The dimension of breadboard on PCL-720+ is 30 ×18 too, but two rows are occupied by a 5V line and a GND line. So the actual free space for the breadboard would be 30 ×16. (the furthest left row for +5V and the furthest right row for Ground) PCL-720 has been phased out for a period and PCL-720+ is an alternative for it.
