Special Features

Antenna

SAIC (Single Antenna Interference Cancellation) / DARP (Downlink 
Advanced Receiver Performance)
Rx Diversity (receiver type 3i - 64-QAM) / MIMO

GPIO

10 I/O pins of the application interface programmable as GPIO.
GPIOs can be configured as low current indicator (LCI).
GPIOs can be configured for antenna diagnosis.
GPIO1 can be configured as dead reckoning synchronization signal.
Programming is done via AT commands.

ADC inputs

Analog-to-Digital Converter with three unbalanced analog inputs for 
(external) antenna diagnosis.

Evaluation kit

Evaluation module

ALS3-US R3 module soldered onto a dedicated PCB that can be con-
nected to an adapter in order to be mounted onto the DSB75.

DSB75 

DSB75 Development Support Board designed to test and type approve 
Gemalto M2M modules and provide a sample configuration for applica-
tion engineering. A special adapter is required to connect the ALS3-US 
R3 evaluation module to the DSB75.
