00005    
00006    Additionally it was tested with a shield where the SARA-G350/U260/U270 RX/TX/PWRON 
00007    is connected to D0/D1/D4 and the GPS SCL/SDA is connected D15/D15. In this 
00008    configuration the following platforms were tested (it is likely that others 
00009    will work as well)
00010    - U-BLOX:    C027-G35, C027-U20, C027-C20 (for shield set define C027_FORCE_SHIELD)
00011    - NXP:       LPC1549v2, LPC4088qsb
00012    - Freescale: FRDM-KL05Z, FRDM-KL25Z, FRDM-KL46Z, FRDM-K64F
