TOOLSTICK C8051F321 DAUGHTER CARD USER’S GUIDE
1. Handling Recommendations
To enable development, the ToolStick Base Adapter and daughter cards are distributed without any protective
plastics. To prevent damage to the devices and/or the host PC, please take into consideration the following
recommendations when using the ToolStick:
Never connect or disconnect a daug hter card to or fr om the ToolStick Base Adapter while the Base Ada pter
is connected to a PC.
Always connect and disconnect the ToolStick Base Adapter from the PC by holding the edges of the
boards.
Figure 1. Proper Method of Holding the ToolStick
Avoid directly touching any of the other components.
Figure 2. Improper Method of Holding the ToolStick
Manipulate mechanical devices on the daughter cards, such as potentiometers, with care to prevent the
Base Adapter or daughter card from accidentally dislodging from their sockets.

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 an LED, 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 component s.
