MakerFocus PWM Servo Motor Driver IIC Module 16 Channel PWM Outputs 12 Bit Resolution I2C Compatible with Raspberry Pi 4 3B+ 3B Zero/Zero W/Zero WH and Jetson Nano

MakerFocus PWM Servo Motor Driver IIC Module 16 Channel PWM Outputs 12 Bit Resolution I2C Compatible with Raspberry Pi 4 3B+ 3B Zero/Zero W/Zero WH and Jetson Nano

Q: Can I power this via wall power while it is hooked up to my jetson nano?

Hi, you need not to power it. It is installed on jetson nano. You could power jetson nano.

Q: I removed the 0r resistor as recommended and now my board doesn’t work, even if i power it externally via the vin. fixes?

What was the resolution of this? I want to remove the resistor to externally power the servos but dont want to break the board.

Q: Is there a power supply for the HAT that works from a wall outlet?

The User Manual is listed under the documentation URL posted: https://www.waveshare.com/wiki/Servo_Driver_HAT It says what the VIN DC power supply voltage range is. 6-12VDC

Q: Schematic says pi's 5v, servo 5v, and regulator 5v all connected together. servos draw power from pi! regulator 5v out and pi 5v contend! is this ok?

When I run my raspi 3 from a standard usb I often get a low voltage warning. To make up for this I spliced a usb cable onto a buck converter that steps down a higher voltage source to about 6V (I started the converter at 5V and slowly cranked it up until the low voltage message disappeared). With this I have run 4 servos with this board at once, however the usb touchscreen I use with the pi tends to go out.
