2D laser mouse sensor ( ADNS 6010 ) measurements

Laser optical mouse is low cost solution for accurate computer cursor positioning today’s.
Concept of mouse position sensor data evaluation and possibility to determine position in two axes is not well-
known. This article explains laser optical mouse sensor principle and presents measurements on sensor
ADNS6010, especially precision, speed and reliability.

Nanotron Localization module

nanoLOC AVR Module

Small Form RF Module Integrating nanoLOC TRX Transceiver and ATmel AVR Microcontroller
This smart nanoLOC AVR Module is only 35 mm by 14 mm and less than 3 mm thick. Yet, within this small form factor it integrates all the required components for a complete RF module based on Nanotron’s innovative nanoLOC TRX Transceiver. This module uses the Atmel AVR ATmega644 microcontroller and includes a band pass filter, a balun, and an integrated 2.4 GHz chip antenna.

Due to the chip’s unique chirp pulse, adjustment of the antenna is not critical. This significantly simplifies the system’s installation and maintenance (“pick and place”). A sophisticated MAC controller with CSMA/CA and TDMA support is included, as is Forward Error Correction (FEC) and 128 bit hardware encryption. To minimize software and microcontroller requirements, nanoLOC also provides scrambling, automatic address matching, and packet retransmission.
