Functional Overview
The YX-1010MKdesigned by Dragon basing on the MT3339 is a new generation of GPS receiving module. It’s up to 66 acquisition and 22 simultaneously tracking channel,ultra-high sensitive GPS receiving module. Based on new highly integrated MTK chips and meticulously integration key parts of Dragon. In the same chip specifications, this product has faster GPS signals ability to capture, lower power consumption, more strong anti-jamming performance and more wide working voltage range.
YX-1010MKmodule designed with industrial requirements, using stamps package, can adapt to wet high temperature, electromagnetic interference etc. odiously working environment. It is widely used in monitoring, positioning, mapping, navigation, security applications.

OPERATING DeSCRJPTion
TIMEMARK
This pin provides one pulse-per-second
output from the board, which is synchronized to GPS time. This is not available in Trickle Power mode. If do not use it, Just NC.
Wake Up
System power controller, when YX-1010MK Power ON, this pin will output 3.3Vdc.
RF_IN
This pin receives signal of GPS analog via external active antenna. It has to be a controlled impedance trace at 50ohm. Do not
have RF traces closed the other signal path and routing it on the top layer. Keep the RF traces as short as possible.
TX
This is the main transmits channel for outputting navigation and measurement data to user’s navigation software or user written software. Output is TTL level, 0V ~ 3.3V.
RX
This is the main channel for receiving
software commands from MTK demo software or from your proprietary software.
VBAT
This is the battery backup power input for the SRAM and RTC when main power is off. Without the external backup battery, YX-1010MK
will always execute a cold star after turning on. To achieve the faster start-up offered by a hot or warm start, a battery backup must be connected. The battery voltage should be between 2.5V and 3.6V.
VCC
This is the main power supply to the engine board. (3.1Vdc to 3.6Vdc)
SOFTWARE COMMAND
NMEA Output Command
NMEA 0183 Protocol
The NMEA protocol is an ASCII-based protocol, Records start with a $ and with carriage return/line feed. GPS specific messages all start with $GPxxx where xxx is a three-letter identifier of the message data that follows. NMEA messages have a checksum, which allows detection of corrupted data transfers.
The YX-1010MKsupports the following NMEA-0183 messages: GGA, GSA, RMC. The module default
NMEA-0183 output is set up GGA, GSA, GSV, RMC and default baud rate is set up 9600bps. Table 1: NMEA-0183 Output Messages
