I have to do it, there are two Power supply + And one power supply -, you butcher into 3 separate PCB.

the CCS requires ~5V to operate correctly.

The recommended minimum supply voltage is: regulated output voltage +7V

Quanghao,

I have a complete LV shunt pcb from you sometime ago, but can't find the schematic for it even I search your forum and or your shop. It says V 1.0 on the broad but there is no Leds marked on the broad. Would you please take a look and advise where I could find the schematic so I could go on with my project - The Lightspeed attenuator.
Thanks

Albert

BTW you can email me if you want.

Q1 IRF9520, Q2 BC560, Q3 K170, Q4 BC550, Q5 K170, Q6 D45H8. You can also check with the picture attached.
Thanks
