Hi, I have negative polarity on output from transformer (-200 V). So diode D2 is closed and on C13, C10 is no voltage. I Suppose that transformer's winding is reversed. Unfortunately I see no chance to repair it. Any idea?

Tamara, you have badly soldered DZ4 diode. See: "There is an error at PCB - Zener diode marked DZ4 should be mount in the way shown at schematic."

*Solved*

Backlight was shining if I shorted with wire pin 2(VDD) and 15(+backlight). Then I try connect another display with another expander and it works. I probably damaged expander during assembling.

My sensor works too.

But display backlight don't work. Anyone has the same problem? I use I2C expander.

Thanks for the part list...

What will be maximal current in inductors? I can choose inductor with load limit 0,285 A or 0,56 A. What do you recommend me to buy?

I have noticed that in the part list is I2C expander for LCD. Also there is note:

I2C Expander for LCD (slightly modified, mechanical compatibility only with type shown here)


I am not sure what expanders are compatible. For example this set of LCD and expander is OK?

I think there is no problem. All of us know before ordering that kits will be sent no earlier than March.
