Recommended GPS Active Antenna
It's recommended to use a GPS active external antenna with supply voltage of 3.3VDC and a current draw of 15mA maximum. The quality of the GPS active external antenna chosen is of paramount importance for the overall sensitivity of the GPS system. A GPS active external antenna should have ≥ 20dB gain and a noise figure ≤ 1.5dB, which applies to more than 90% of the antennas available in the market.

VDD( DC Power Input)
This is the main power supply for the Engine board. The power range is from 3.3V ±10%( the maximum and minimum voltage is 3.0V to 3.6V). Suitable decoupling must be provided by external decoupling circuitry.
GND
GND provides the ground for the Engine board. Connect all grounds.
VBAT
This is the battery backup supply that powers the SRAM and RTC when main power is removed. The input voltage level is from 1.8V ~ 3.3V. Without an external backup battery or on board battery, engine board will execute a cold start after every turn on. To achieve the faster start-up offered by a hot or warm start, either a backup battery must be connected or battery installed on board.
TX0
NMEA_TX, UART output, 3.3V LVTTL logic level. This is the main transmit channel and is used to output navigation. The default setup is NMEA Output, 9600bps, 8 data bits, no parity, 1 stop bit. The default sentences are GPGGA, GPGSA, GPRMC, GPGSV once per second.
RX0
NMEA_RX, UART input,3.3V LVTTL logic level. This is the main receiving channel.
It is generally recommend you to consider serial resistor between a certain CPU's TX and
SLE-1613 module’s RX in order to reduce possible noise interruption for noisy CPU's transmission. The resistor value should be decided by set testing in user application.
Based on our experience, 10KΩ resistor could be applicable for -40 to 80°C temperature condition.
RESET
This is the function to restart the system, If the pin is lied to low. Leave unconnected if not used.
ANT
The Module supports passive & active antennas. The line on the PCB from the antenna(or antenna connector)has to be a controlled line (Micro strip at 50ohm at 1575.42MHz).
The input provides also a bias supply( +3.3V typ.)
