  • iOLab System Overview

    -  Wireless iOLab unit communicates with USB dongle using 2.4GHz ISM band.
    -  Powered by 2xAA batteries.
    -  TI-MSP430F5329 microcontroller, TI CC2543 radio.
    -  Dongle communicates with PC/Mac via simple virtual comport interface (i.e. no special USB programming required).
    -  Individual sensors synchronized and read out in various predefined configurations.
    -  Up to 4.8 kHz sensor sampling.
    -  One dongle can synchronously read data from two iOLab remotes.
    -  Wireless range up to 100 feet. RSSI included in data.  -  Size 30 mm x 75 mm x 130 mm, Weight: Remote 148 g (w/o batteries), Dongle 8g.
