Power Supply Regulated power for the DL-1818N-GCMRisrequired. The VCCPinNeed a stable DCvoltagesupply. Power supply ripple must be less than 30mV.The input voltage Vcc should be 2.8V~4.3V, Recommended power supply voltage is 3.3V, maximum current is 20mA. Suitable decoupling must be provided by external decoupling circuitry. 1.3. UART Ports The module supports two full duplex serial channels UART.All serial connections are at 3VCMOS logic levels, if need different voltage levels, use appropriate level shifters. The baud rate of both serial ports are fully programmable, the data format is however fixed: X, N, 8, 1, i.e. X baud rate, no parity, eight data bits and one stop bit, no other data formats are supported, LSB is sent first. The modules default baud rate is set up 9600bps, however, the user can changethe default baud rate to any value from 4800 bps to115kbps. UARTport can be used for firmware upgrade, NMEAoutput and PMTK proprietary commands input.
