Cellular Connectivity¶

Connections¶

The Blues device must be connected with its own 24v power supply.

The Opta connects to the Blues expansion with a standard AUX connector (it’s at easy as connecting two LEGO pieces), and the Opta uses that connection to communicate with the expansion’s Notecard via I2C.

Arduino Opta Configuration¶

The Arduino Opta must be configured to communicate via the Blues device. This is done by selecting the correct option in the 'Configuration Mode'.

External Antenna¶

Must be a multi-band antenna with a Male SMA connector. Connect to 'MAIN' connector.
