The Raspberry Pi is a wonderful little computer, but one thing it isn’t very good at is controlling DC Servo Motors - these motors need very specific and repetitive…

Can I also connect other things like a ultra sonic sensor to this? And if not how can I connect things other than servos to this

Hi Keenan,

Welcome to the forum :slightly_smiling_face:

The HAT communicates with the Raspberry Pi via the I2C interface using the address 0x40. Since the I2C interface is a bus-style protocol, you should still be able to use every pin of the Pis 40 pin GPIO connector with no issues, provided you don’t have two things connected both using the same two I2C pins and address 0x40.

With the electrical connections open the issue then becomes how to physically plug in the other devices you want to use. There are two main options for that:

  1. Use stacking GPIO headers that stick through the HAT so you can still connect to the GPIO connector on top of the HAT.
  2. Solder headers to use the pins that are broken out to different through-hole points on the HAT as shown in the image below.
