Silicon Labs 12-pad Capacitive Touch Evaluation Board for CPT112S

CPT112S TouchXpress Capacitive Touch Evaluation Kit. The Silicon Labs CPT112S TouchXpress Evaluation Board has 12 capacitive touch sensitive pads with an optional 4 channel touch slider together with a buzzer to confirm touch. The CPT range is designed to make the switching from traditional buttons to capacitive touch buttons as simple as possible. The board can be connected to a host processor using the expansion header or breakout pins or connect to a PC using USB. This Evaluation Board is pre-loaded with software demos and interfaces with all EFM8™ and EFM32™ families of MCUs. Although capacitive sense requires complex technology these devices are not complicated to use or adapt to your needs. Using Silicon Labs Simplicity Studio you can easily configure the device to your requirements. It also provides real time profiling to aid rapid development. Integrate the CPT112S capacitive sense buttons and slider by interfacing into an I²C interface. Silicon Labs CPT devices continuously monitor the touch pads enabling the main processor to remain in sleep mode for longer to reduce overall power consumption. Low-power usage and a small form factor make them ideal for modern, portable designs. Available in 20-pin QFN packages and just 3 x 3 mm. A 7 capacitive sense pad version without a slider is also available from RS: Silicon Labs CPT007B Capacitive Touch Evaluation Kit (RS ; 914-0031 914-0031 )
