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

[Bbe]

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

This is not a selfie, just a photo


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?

[Bbe]

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

[andy_con]

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

[Bbe]

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

[Bbe]

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