I found a solution, I have to set it up first, then the servo can work.
Thank you for your response.

I want to use M5BURNER to burn the firmware but it is unsuccessful.
After I press the BURN button and set the WIFI information, the burning process is not started.

了解，是有人說可以，讓我在這兒發問題，然後他就會給我一個範例！

雖然8servo Hat是為stick設計的，但是有沒有可能用M5Stack core連接它，並且使用UIFlow的積木來操緃？

我使用M5STACK連接RFID模塊，好像只能讀取卡號及地址1和地址2，其他的好像不行！

@ajb2k3 said in About Hat 8servos:

you dont have power to the servos. is the power switch in the correct position?

Yes,the power is switch in the correct position.
I am sure that it is not a power problem.

@ajb2k3 said in About Hat 8servos:

When the program is executed, the pressure on the servo horn is rotatable.

I record a mp4 video. The RGB worked but Servo not.
