UNO from aliexpress --> avrdude: stk500_recv(): programmer is not responding

[greazr]

Hello,

I purchased a Uno + wifi from a store on aliexpress, but cannot seem to get programs to upload. I see the error message: avrdude: stk500_recv(): programmer is not responding

I did download and install the CH341SER.ZIP driver. I can connect the board via USB and I hear the Windows connect sound. I see the port in device manaager.
I made sure I selected the correct board and port is seleceted in the IDE. But when uploading the program there is a long wait and then ->

Any ideas?

Uno + wifi

Check the settings of those little DIP switches on the board. I think they need to be in the right position in order to upload to these boards.

Be sure you select the correct bord in the tools menu.

DIP

Thank you man, No manual came with the board, but I set switches 3 and 4 to ON and now the program will upload.
