Source of the experiment - with a un0rick board

Probe model

• HP 21412A (seems like HP 21402A would work too). A good choice to try mechanical scanning. Simple piezo, simple motor.

Make sure that the liquid is present in the head.

Connections

• The motor (black/white pair) is driven by a DRV8834 at 5V. Setup is as follows:
  • STEP: 400us period square wave.
  • M1: HIGH
  • !SLEEP: HIGH
  • Connection to motor: A1/A2 or B1/B2
• Piezo: yellow coax
