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 thei r 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 target microcontroller and application circuitry are located on the daughter card. Some daughter cards, such
as the C8051F931 Daughter Card, are used as general-purpose development platforms for the target
microcontrollers and some are used to demonstrate a specific feature or application.
The C8051F931 Daughter Card includes a pair of GPIO controlled LEDs, a potentiometer, a switch connected to a
GPIO, a capacitive touch sense switch, an d a sm all pr ototyping are a which provid es access to all of the p ins 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. The C8051F931 Daughter Card also includes an A76 1.5 V alkaline
battery which can be used to power the board when not connected to the Toolstick Base Adapter. The C8051F931
will continue to operate from the single “button cell” battery until the supply voltage drops below 0.9 V.
