ADNK-3043-BRBT
Bluetooth Optical Mouse Designer's
Avago Technologies Broadcom have collaborated produce Bluetooth mouse reference design kit. mouse based Avago Technologies' ADNS3040 power mouse sensor, Broadcom's BCM92042MDX-B88 Bluetooth module. receiver dongle implemented with Broadcom BCM2045 Chip. This reference design provides power-efficient feature-rich solution neat package. Avago Technologies ADNS-3040 power navigation sensor, 18-pin staggered dual inline package (DIP), based SmartSpeed self-adjusting frame rate optimum surface- tracking performance. sensor measures changes position optically acquiring sequential surface images (frames) mathematically determining direction magnitude movement. high-performance, low-power architecture capable sensing high-speed mouse motion while prolonging battery life, performance areas essential demanding wireless applications. ADNS-3040 sensor, along with ADNS-3120-001 lens, ADNS-2220 clip HLMP-ED80 form complete compact mouse tracking system. There moving part, which means high reliability less maintenance user. addition, precision optical alignment required, facilitating high-volume assembly. Broadcom BCM92042MDX-B88 Bluetooth module small size, good performance less power consumption Bluetooth Module support Bluetooth solution. built BCM2042 Bluetooth single-chip Bluetooth compliant, standalone baseband processor with integrated 2.4-GHz transceiver. helps customer

developing their Bluetooth products short time less effort performance tuning. built-in switching regulator BCM2042 chip enables BCM92042MDX-B88 module provide power source which useful most ICs. more information about BCM92042MDX-B88 module BCM2042 chip, please refer datasheet. Bluetooth dongle included this reference design integrated with industry-leading WIDCOMM Bluetooth Software Broadcom Coorporation). Bluetooth dongles needed only laptops without built-in Bluetooth capability. There ways connecting mouse first connect provided USB-enabled Bluetooth dongle non-Bluetooth enabled PCs. Bluetooth-ready PCs, have plug
dongle mouse. Based 2.4GHz Bluetooth technology, data generated from displacement detection button status mouse encoded with pre-defined serial type protocol handled firmware BCM2042. stage, encoded data used GFSK modulation. captured data from receiver stage decoded with corresponding packet format used mouse applications. final data sent host through Bluetooth interface transport interface.
