TB3 board TTL port problem
1. After the board is running normally, press the test button, the servo No. 1 can be rotated, and the second is not responding.
2. Replace the other two TT ports, the 1st can still be rotated, and the 2nd can't be rotated.
3. Replace the openCR board, both the No. 1 servo and the No. 2 servo can be rotated
Here are a few videos, all using the same servo
Thank you for the attached video.
