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.
