Hi, Churilo,
I am currently using the board in your project - DDS single-channel three-signal generator based on AD9833. Now I have a problem with the board, when I connect the 5V port and gnd port to the bench power supply, it is short connected, and 630mA current flow from power to the gnd!! I tried to measure the impedance between 5V and gnd, it is very small, and I think the PCB power is short connected to the gnd. I also used a USB to TTL connect to the UART port, it has a same problem, and the board is over heated. Could you please help me, if this problem happen, where could be the short-connected point? I manufacture the board by your PCB layout and assemble the components with the BOM in the project folder by PCBWAY.
Many thanks for your helps,
All bests,
Jin
