The Arduino I2C / SPI / Onewire shield is pretty much a board with pins which would allow you to connect these types of devices. The I2C already has the pins pulled up and the Onewire portion has the pin pulled up as well.

Overview

Demo:

Features:

• 90 degree pins means it's still stackable
• All pins are available even if there's another board on top
• I2C bus is pulled high
• Onewire bus is pulled high

The best part about this shield is that both the SPI and Onewire portions have jumpers which allow you to select which pins to connect the devices to. This allows other shields to be connect and lets you have the ability to change which pin the devices on this shield operate to allow great expandability.
