| Oct 26, 2021 at 11:21 | comment | added | mrneedshelpalot | This is my first PCB design with IC's (I did PCB with pin headers). I will make polygon and I will use via GND holes.(is this what you wanna say ,sorry again I don't know very well about PCB design) | |

| Oct 26, 2021 at 11:10 | comment | added | DamienWontContributeToAITheft | You will be using the RP2040's single GND pad anyways. Grounding is a huge topic! But as a general rule make sure that the motor drivers have a direct path to the power connector and back, and keep the other chips away. | |

| Oct 26, 2021 at 10:31 | comment | added | mrneedshelpalot | Thank you, DamienD. This answers my questions. "As long as you don't have noisy motor drivers". I couldn't say it I didn't know motor driver can be problem. I will use D-808 Motor driver but I will use only signals pins. I will give power D-808 from another adapter ( Switch mode adapter.) Will it be a problem ? I am using hx711 IC too but It is working good with GND. | |
