Variable Voltage Breadboard Power Module

This is a continuation, or let's say a respin/feature changing mod on an existing project. My existing breadboard power module has the usual 3.3v and 5.0v options on the rails. This works well in most cases, but sometimes I need other voltages... This is an attempt to address that. giving access to 3.3v 5.0v 7.2v 9.0v and also a straight through VInput directly from the bench power supply, all with the change of a jumper or two... Based on the LM317G this module can source up to 1500mA per rail. It is however a bit bulky at this stage, as I chose to go with variable resistors to adjust the voltage levels once at setup... that may be changed to something more elegant in the future. The PCB was manufactured to true to my design, and seem to be of the usual high quality that I have come to expect from PCBWay. Thank you
