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.
GPIO2 can be configured as 700MHz antenna switch control signal.
GPIOs can be configured as remote host wakeup lines.
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 R4 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
R4 evaluation module to the DSB75.
