4 On-Board Peripherals
4.1 RESET and ON_OFF Push-Button
The EVA1035-H holds two push-buttons:
• nRST (RESET)
• ON_OFF
The nRST button is used to get a full reset of the GPS module. All parameters are
stored in non-volatile memory. After pushing this button the module starts again from
the beginning.
The ON_OFF button puts the A1035-H GPS receiver into Hibernate state if it is on
and wake up if it is in sleep state. During sleep state the receiver draws 20µA typically
and maintains RTC and SRAM.
Hibernate mode is supported by Firmware version 3.2.5 and later.
4.2 External Antenna Connector
The A1035-H supports two antenna inputs:
• The on-module antenna.
• The antenna connector “External Antenna” leads to pin 8 of the A1035-H GPS
receiver which supports active GPS antennas.
It can be switched between the two antenna inputs by using the ANT_SW pin of the
A1035-H connected to the DIP switch on board the EVA1035-H evaluation kit.
Setting the DIP switch to “OFF” means the on-module is activated.
Setting the DIP switch to “ON” means the External Antenna input is activated.
