The 5K LE by QPAD uses a Laser sensor from Avago, specifically the ADNS-9800, providing a DPI/CPI range of 200 - 8200 cpi. This results in a tracking speed of 3,8 m/s, 150 ips, and a maximum acceleration of 30G. It uses a USB connection with a 2m braided cable.
The heart of the QPAD 5K LE is a brand new next generation gaming-grade laser sensor from Avago - the A9800. This sensor offers previously unmatched accuracy and tracking abilities, with a minimum of ripple, that often plague other mice on high DPI-settings. The 9800 is capable of delivering a resolution ranging from 200 to a stunning 8200 CPI/DPI, with a sample rate of 12 000 fps. This has previously only been possible though firmware extrapolation, or lens magnification, with catastrophic results in terms of accuracy and precision. The QPAD 5K LE offers true 8200 CPI, and will deliver absolute performance and precision, every time, all the time!
