OEM Bluetooth I/O Module OBI411

Key features

The Bluetooth I/O Module OBI411 implements wireless IO functionality and supports 16 digital IOs and 4 AD converters, which can be controlled via either IO signals or via a serial IO protocol, for example using an Android phone and application. With the Bluetooth stack embedded you can be up and running quickly as there is no need for a driver or stack in your host. The module is fully Bluetooth qualified and radio type approved for Europe, US and Canada. It also has the connectBlue standard interface for compatibility over time and radio technologies.
