 # LaserProfilometer - Power Supply
-BP VUT FIT 2022 - Linear Laser Profilometer
 
-Adjustable power supply for laser diode 
+## BP VUT FIT 2022 - Linear Laser Profilometer
+
+## Power to diode can be adjusted by applying voltage to VSET (0V = 0mA on LASER, 3V = 70mA on LASER) or by sending PWM signal to VSET

+
+## !! Always have diode connected to LASER connector when applying voltage to VSET or VIN (5V) !!
+
+
+
+| Connector   | Max Value   |
+| ----------- | ----------- |
+| VSET (IN)   | 3V          |
+| LASER (OUT) | 70mA        |
+| VIN (IN)    | 5V          |
