+/* This example was tested on C027-U20 and C027-G35 with the on board modem.
+
+ Additionally it was tested with a shield where the SARA-G350/U260/U270 RX/TX/PWRON
+ is connected to D0/D1/D4 and the GPS SCL/SDA is connected D15/D15. In this
+ configuration the following platforms were tested (it is likely that others
+ will work as well)
+ - U-BLOX: C027-G35, C027-U20, C027-C20 (for shield set define C027_FORCE_SHIELD)
+ - NXP: LPC1549v2, LPC4088qsb
+ - Freescale: FRDM-KL05Z, FRDM-KL25Z, FRDM-KL46Z, FRDM-K64F
+ - STM: NUCLEO-F401RE, NUCLEO-F030R8
+ mount resistors SB13/14 1k, SB62/63 0R
