Title: Problem with my custom BT815 circuit
Post by: FlorianG on May 25, 2020, 01:14:06 AM

Hello,

I made this circuit based on the 815 bt and it does not work,
I do not know if it is a design defect or asenblage but the code works with the VM816C50A and FT811.

Can you tell me if you see errors on my diagrams?
thank you in advance for your help.

Sorry to say so, but your schematic is nearly unreadable.
Using labels for GND would help and not drawing signals thru the symbols.

Hello,

Yes, unfortunately your schematic is quite hard to read, could you label the supply lines and ground?
Are the supplies on the board correct? Is there a voltage on VOUT1V2?

Best Regards,

GND connection on pin 33 looks suspicious at a glance. (no connection dot shown)

Thank you for your answer, the pin 33 is well connected to the GND.
Sorry for the readability problem, before I didn't use the label.

Hello,

What are the voltage supplies on the board sitting at? And is there a voltage on VOUT1V2?
