Thank you very much. Improved!

Is there a problem when powering the mobile battery from Micro USB with NyBoard and Raspberry Pi connected? If I power the Raspberry Pi from NyBoard and Micro USB at the same time, will the Raspberry Pi be damaged?

Thanks for your advice!

I understand. Nybble and Raspberry Pi are not connected, and I am planning to power the Raspberry Pi from a mobile battery. And I want to have a pi camera on my Raspberry Pi. In that case, how much weight can I put on Nybble's back?

I am thinking of powering the Raspberry Pi from a mobile battery. I want to put a 180g mobile battery on top of a Raspberry Pi. In this case, is it likely that a servo trouble will occur?

Thank you very much! I will think about it.

Thank you for your immediate response. Currently I have such a connection. Will it improve if I use a higher voltage (eg 9v) battery?

Thanks to your post suitable for solving my problem, My servomotor is working again. I appreciate your help. great!

Thank you for your kind reply. I seem to have misunderstood. When the servo connected to the 8th is connected to the 12th, the servo moved by running "m12 0". There seems to be a problem with the servo itself connected to the12th. I tried connecting the 2th servo to the 12th as a trial, but it didn't work. The 12th and 2th servos have heat, but the other servos do not have heat. Are these two servos broken? Is there a way to check if the servo is broken?

Thank you for your answer! I confirmed that the serial signal was read and output in the terminal. I seem to have misunderstood.

@Rongzhong Li Thanks for your advice. I'll try.

Thank you for your reply. I am sorry. The action is very cute for me. Is it difficult to get this jumping gait action done using my kitten?
