Some Examples

Digital Circuit With One Supply Rail

If you're building a digital circuit with a single supply rail (typically 3.3V or 5V), make the following connections

• Bridge jumpers TIE+ and TIE-.
• Bridge jumpers JG5 or JG6.
• Install a 2 position 5MM screw terminal. As seen above
  • The red wire is the supply voltage.
  • The black wire is ground.

When you install components, they can pick up the supply voltage on either + rail, and ground on the - rails or at the center ground trace.

Analog Circuit With Bipolar Rails

For an analog circuit with a bipolar power supply, configure the jumpers as follows

• Bridge jumpers TIE+ and TIE-.
• Install a 3 position 5MM screw terminal. As seen above
  • The red wire is the + supply voltage.
  • The blue wire is the - supply voltage.
  • The black wire is ground.

Components can pick up the positive supply voltage on either + rail, the negative supply voltage on either - rail, and ground on the center trace.

Multiple Boards

If you're building a larger circuit using more than one of these boards, they can share a power supply. The most common configuration is known as "star power distribution." The power supply forms the center of the system, and each board is connected directly to it.

Or, redrawn for simplicity.

This configuration makes a direct connection between the supply and each board.
