This file is a user manual for Silicon Laboratories's product ToolStick CapTouchSense Daughter Card, which introduces the product's features, usage methods, and precautions.
The ToolStick CapTouchSenseDC daughter card provides a C8051F931 microcontroller, four LEDs, a mechanical switch, four capacitive touch switches, and an A76 1.5 V battery. It plugs into a ToolStick Base Adapter that supplies USB debug and UART communication to a Windows PC.
The guide covers handling recommendations, hardware setup, required Silicon Labs software (IDE, Keil tools, Configuration Wizard 2, and Terminal), demo applications such as a memory game, and how to use the board as a development platform with full pin access and optional external components.
