TWELITE CUE (BLUE / RED) Datasheet

Version 1.1.1

TWELITE CUE integrates the TWELITE wireless microcontroller, 3-axis accelerometer, magnetic sensor, coin cell battery holder, and antenna into one package. It comes pre-installed with a dedicated CUE application (firmware), and starts operating immediately when a CR2032 coin cell is inserted. With low power consumption, it can operate continuously for years.

It is ideal for those who have ideas for using wireless tags but are not confident in hardware or software development, or who have limited development resources.

TWELITE CUE is a compact wireless tag with excellent transmission range and long battery life.

Precautions

Inserting the Coin Cell

Insert the CR2032 coin cell with the positive side facing the positive side of the holder. If the LED on the TWELITE CUE blinks three times, it is functioning properly.

Ensure correct battery orientation. Inserting it backwards may cause overheating and damage.

Due to its structure, the battery holder of TWELITE CUE is prone to detachment at the soldered area. Please follow the precautions below:

When removing the coin cell, it is recommended to gently press the battery holder from above to avoid stressing the soldered section.
When operating TWELITE CUE, use a dedicated case to hold down the battery holder from above.

Disposal

Dispose of this device in accordance with your local municipality’s ordinances and regulations. Please consult your local authorities for details.
