General Description
Delin Comm ES1108 is a complete GNSS module. The module can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS and QZSS or BEIDOU .It features ultra-low power consumption and small form factor. With the superior and performance even in urban canyon and dense foliage environment.
ES1108 is a super low-power upgraded GNSS module with a working power consumption of only 5MA, plus -165dbm tracking sensitivity extended positioning to cover every corner.The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones,Sports watches, handheld devices, IOT and other portable devices

1.2Power Supply
Regulated power for the ES1108 is required. The VCC Pin Need a stable DC voltage supply. Power supply ripple must be less than 30mV. The input voltage Vcc should be 2.8V~5.5V, Recommended power supply voltage is 3.3V . maximum current is 8.5 mA. Suitable decoupling must be provided by external decoupling circuitry.
1.3UART Ports
The module supports two full duplex serial channels UART. All serial connections are at 3V CMOS 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 115200bps, however, the user can change the default baud rate to any value from 4800 bps to 115kbps. UART port can be used for firmware upgrade, NMEA output and SONY proprietary commands input.
