Evaluation board for radio module Erinome-II
2 Functional description
The evaluation board offers the user the possibility to put the compatible GNSS module into
operation and to evaluate its features. Furthermore, it represents our reference design for the
integration of the compatible GNSS module in an application board.
The evaluation board can be connected to an USB port of a PC. For the connection to a mi-
crocontroller system the development board is equipped with a multi-pin connector which gives
access to all necessary pins of the GNSS module. Jumpers allow the module to be discon-
nected from components such as the USB interface which are not required.
In the version with the Thyone-I RF interface (part number 2614029237011), the radio module
Thyone-I (on the evaluation board) and the corresponding USB radio stick (available in the
evaluation kit) can be used to communicate with the GNSS module through RF link, instead
of USB cable. In this setup, batteries can be used to supply the evaluation board, making it
completely standalone.

3.4 Switches and Buttons
3.4.1 RESET GNSS button
Internally the active low reset input of the Erinome-II is connected via a RC combination with
the power supply to ensure a proper startup of the module. /RESET pin is connected to this
button which provides the possibility for hard reset. Please refer to the module specific manual
for detailed information.
3.4.2 ON/OFF Switch
ON/OFF Switch is connected to the GNSS module’s ON_OFF pin. This gives the user the
possibility to switch between the operating modes. Please refer to the module specific manual
for detailed information.
Before connecting the evaluation board to the PC the ON/OFF switch should
be in OFF position (Hibernate mode), only after USB initialisation the ON/OFF
switch should be switch to ON position (Full power mode)
