1 Introduction A5135-H is an antenna module with SiRFstarV™ Flash based chip and an on-board patch antenna (15mm x 15mm x 4mm). It is a new version of our existing A2035-H & A2235-H with new GNSS support. To support an easier migration for existing cus- tomers, we kept the same pin assignment.
1.3 RoHS and Lead-Free Information Lantronix’s products marked with the lead-free symbol either on the module or the packaging comply with the "Directive 2002/95/EC of the European Parliament and the Council on the Restriction of Use of certain Hazardous Substances in Electrical and Electronic Equipment"...
1: Introduction 1.4 Label The A5135-H label (size: 12.0x 4.0 mm²) contains the following information: Figure 1: A5135-H label The label is placed on the side of the GNSS antenna. The data matrix code holds the product type, part number, software release, hardware release, factory code, year &...
2 Ordering Information 2.1 GNSS Receiver A5135-H The order number is built as follows: A5135-Hxxxx A5135-H is the model name. The “xxxx” refers to the current part number on the module. 2.2 Packing The A5135-H GNSS modules come in a tape and reel package suitable for pick and place machines.

3 Quick Start To allow an easy and quick start with the A5135-H module, this chapter provides a short overview on the important steps to be taken to receive NMEA messages with position information on a serial port (UART). NOTE 1: The A5135-H needs an external pull-up resistor to be configured for UART operation.
Figure 6: RS232 level shifter for minimum configurations Remarks: • Place C1 to C5 (here: 0.1µF) close to MAX3232. For capacity values see datasheet of actual component used. • Use 3.3V level shifter (MAX3232 or equivalent). GNSS Receiver Module A5135-H User Guide...
SiRFstarV ROM chip set. 3.5 Self-start configuration In order to minimize the GPIO required for operating A5135-H, WAKEUP (pin 4) and ON_OFF (pin 19) can be tied together for entering the self-start mode such that no ON_OFF pulse requires.

GPIO2 None Leave open None Leave open None Leave open TM_GPIO5 Output Time Mark (1PPS signal) on the A5135-H is NOT for timing applications. None Leave open None Leave open ON_OFF Input Power control input. High-level input initiates system transitions from OFF to ON,...
This is a stress rating only. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. GNSS Receiver Module A5135-H User Guide...
7 Mounting This chapter describes the suggested mounting process for the A5135-H GNSS re- ceiver modules. In a RoHS, compliant product with a RoHS compliant process it is recommended to use chemical tin as the counter-part to the module’s pins. This will guarantee highest resistance against shocks.
Time 25°C to peak temperature 8 minutes max. Table 8: Reflow soldering profile A5135-H As results of soldering may vary among different soldering systems and types of sol- der and depend on additional factors like density and types of components on board, the values above should be considered as a starting point for further optimization.
50 Ω PCB strip line is required. the strip line needs a good reference ground. Figure 14: Antenna connector strip line A5135-H To achieve the impedance of 50 Ω, the width of the strip line needs to be calculated. It depends on the thickness or height of the PCB layer (both parameters are shown in following drawing).

If no messages then a new toggling should be applied. 10.2 Proper Shutdown A controlled and orderly shutdown while the A5135-H is running in full power mode can be initiated by • Pull the ON_OFF pin to low, •...
GPS+GLONASS satellites. While the current date and time is transmitted in NMEA sentences (UTC), an exact and accu- rate timing signal is provided via the 1PPS pin of the A5135-H GPS+GLONASS re- ceiver.
11 Evaluation Kit EVA5135-H For demonstration and easy evaluation of GPS+GLONASS performance Lantronix offers an evaluation kit (including one GPS+GLONASS A5135-H module). It contains a USB interface with according drivers to connect easily to a PC. The USB interface is an extension of the serial port 0, therefore sending NMEA sentences and accepting commands.
