U33

U33 - part (control panel) to connect the kit with Boffin
In the application, go to the main menu (CONTROL - PROGRAMMING - MANUALS). Click on CONTROL and the control panel (OP) will appear.

The U33 driver has 5 outputs (D1, D2, D3, D4 and A) and these are controlled using the Boffin app. Outputs D1-D2 and D3-D4 are paired to each control the motor in both directions and can be used to set one of two output voltage levels, called H (higher - 5V) and L (lower - 3V). Output A is low power and cannot control most motors.

You can control the U33 driver via the Boffin app on your bluetooth device in two ways:

1. Control Panel (real-time remote control)
2. Boffin app PROGRAMMING (simple graphical control)

• A - connection output for low current use, 4V output level
