The ToolStick-F321DC kit contains the following items:
ToolStick C8051F321 Daughter Card
A ToolStick daughter card requires a ToolStick Base Adapter to communicate with the PC. ToolStick Base Adapters
can be purchased at www.silabs.com/toolstick.

3. ToolStick Overview

The purpose of the ToolStick is to provide a development and demonstration platform for Silicon Laboratories
microcontrollers and to demonstrate the Silicon Laboratories software tools, including the Integrated Development
Environment (IDE).
The ToolStick development platform consists of two components: the ToolStick Base Adapter and a daughter card.
The ToolStick Base Adapter provides a USB debug interface and data communications path between a Windows
PC and a target microcontroller.
The C8051F321 Daughter Card includes a pair of LEDs, a potentiometer, a micro USB connector, a switch
connected to a GPIO, and a small prototyping area which provides access to all of the pins of the device. This
prototyping area can be used to connect additional hardware to the microcontroller and use the daughter card as a
development platform.
Figure 3 shows the ToolStick C8051F321 Daughter Card and identifies the various components.
