4 Mandatory points for the final tests and tuning
The design of the main board (which the module is connected to) must provide an access to following signals
when the final product will be completely integrated.
The module's firmware can be upgrade over serial or USB links. To proceed, SAGEM recommends that
products based on SAGEM modules provide a direct access to the module serial link or USB through an
external connector or any mechanism allowing the upgrade of the module without opening the whole product.
