When I try to upload code to my board using my new FTDI shiping by aliexpess for the first time, I get an avrdude error:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xa3
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0xa3
After that, I tried uploading a simple code to an Arduino Nano, but the same error appears. I've tried several circuits, but without success.
Please provide a detailed description of your board.
Please provide a list (or schematic diagram if you prefer) of all the connections you made between the FTDI and your board.
Since the primary subject of your post seems to be about the other board, let's focus exclusively on that for now. After that is solved we can circle back to the Nano.
Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting can result in a suspension from the forum.
In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.
