"Big Blue" quad laser diode driver with H-bridge TEC controller and buck converter

Previous thread is too confusing, I decided to start another one :)

This is not a selfie, just a photo
Attachment 44157

This blue board includes:

4 channel highside analog LD driver with bias standby (SBS). Upto 3A/ch
2 channel buck dc-dc converter
1 channel H-bridge (bidirectional) TEC controller. Upto 6/10A @12V

as well as:
start delay, soft start, diodes, baseplate and pcb overheat control and many other features :)

The project is under improvement at the moment...

and how about some sort of output so this information could be displayed in a screen using an arduino?

such as temperature? It is not difficult, but it is not claimed for me )

yes temps, diode current, if somethings over heating etc...

I use NTC as temperature sensors, they are not too accurate for this.. Also, to accurately shows current, need to add a few sensors. For the rest, eg overheating, there are 3 LED's on the board :)

3 leds = very helpful when sealed inside a projector case

arduino = very helpful when projector case fixed on the traverse and folks dancing around :D
decision - to transmit data through wi-fi, he-he
