| The Skylab SKM56 Series with embedded GPS antenna enables high performance navigation in the most stringent applications and solid fix even in harsh GPS visibility environments. |
The module requires a power supply VCC and a backup supply VBAT voltage for non-volatile RTC & RAM blocks. There is no on-board backup battery, which the need for external backup voltage source. It enables the SKM56 module to recover from power failure with either a hot start or a warm start. |
| The module interfaces to the customer＊s application via one serial port, which uses CMOS voltage levels.If RS232 signal levels are required, customer need to use a CMOS-to-RS232 level converter. |
