he power is supplied to EVB via Type-B, and then power to GNSS module via a Linear voltage regulator
(LDO). GNSS module outputs the signals from communication interface on EVB via USB-to-UART Bridge
Chip (CP2102N). There are an antenna interface and a control button on EVB. All functions of the module
are available, including debugging.
