Evaluation kit
Evaluation module ELS81-US module soldered onto a dedicated PCB that can be connected
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 application
engineering. A special adapter is required to connect the ELS81-US evalu-
ation module to the DSB75.
1. HTTP/SecureConnection over SSL version 3.0 and TLS versions 1.0, 1.1, and 1.2 are supported. For
