Enfora Enabler III LPP 3.5.1 ADVANCED TIPS FOR AN RF FRIENDLY LAYOUT 3.5.1.1 GROUND PLANE To ensure the lowest possible EMI emissions and maximum thermal conductivity, it is recommended that all metal tabs on the GSM module shield must be soldered down onto a continuous ground plane that runs under the entire module. Ample ground vias should be provided to create a low impedance ground.
Enfora Enabler III LPP 3.5.1.2 THERMAL RELIEF Because the ground plane acts as a large heat sink, it can affect the solderability of components. A common method to reduce this effect is to use thermal relief around the pad in question.
Enfora Enabler III LPP GOOD RF thermal Figure 3 - Example of a GOOD RF Thermal Relief 3.5.1.3 ANTENNA AND RF SIGNAL TRACE The PCB trace that feeds the RF output port must be designed for a 50 ohm characteristic impedance, coplanar, or routed into internal layers to keep the top layer continuous around and underneath the Enabler module. Ample ground vias should be provided around the RF contacts, the RF trace and launch pad. If possible, keep I/O and power traces away from the RF port.
Enfora Enabler III LPP The RF cable going between the Enable module and the antenna is very lossy, therefore, the length of this cable should be kept as short as possible. 3.5.1.4 VBAT INPUT The Enabler Vbat input can have a relative high current draw that can fluctuate rapidly, especially when transmitting at max power and burst mode. The Vbat interface must be designed to provide the required instantaneous voltage and current with minimal voltage droop.

Enfora Enabler III LPP 5.3 CIRCUIT PROTECTION Other than very low level ESD protection within the module’s integrated circuits, the module does not have any protection against ESD events or other excursions that exceed the specified operating parameters. Generally, ESD protection (typically TVS/Transorb devices) should be added to all signals that leave the host board. This includes VBAT/VCC.
Enfora Enabler III LPP 5.4 CONTROL CONNECTOR SIGNAL DESCRIPTIONS AND FUNCTIONS Note: The following descriptions are intended to provide hardware-level definitions. In some cases, specific lines will have no firmware functionality implemented. Information for each hardware-specific feature will be noted in the appropriate section. 5.4.1 MODULE POWER (PINS 30, 31) The Enfora Enabler III LPP module uses a single voltage source of VCC=+3.3V to 4.5V.
Enfora Enabler III LPP 5.4.2 ON/OFF SIGNAL (PIN 4) The module may be set into a low power ‘off’ mode by pulling the pin low for a minimum of 3 seconds. This will shut down any active functions including GPS and GSM, and stop the MSP430 processor. This is the lowest power mode of the module, it can be ideally used when storing or shipping units and the controller is not to be enabled. Once the module is in the ‘off’ state, it can be turned ‘on’ by holding the pin low for a minimum of 3 seconds.
Enfora Enabler III LPP high. Once the transition from low to high is complete, the micro-controller will boot. The Reset signal is falling edge triggered, so the reset function is set immediately when the signal is pulled low. When using Reset, it will immediately lose the connection to the GSM network, this is not considered ideal. Typically during a normal shutdown, the module will issue a detach request to the network to indicate that it is being removed.
Enfora Enabler III LPP 5.4.8 SERIAL INTERFACES 5.4.8.1 MAIN SERIAL INTERFACE (PINS 17, 18) The pin naming for TX/RX is referenced as a DTE. The DTE device should match their input pins to the Enfora outputs and vice-versa. Module is on 2.2 V logic levels, so appropriate level translation needs to be accounted for.
Enfora Enabler III LPP The key features of the UART in the Enabler III LPP module mode are as follows: • • Baud rate 57600 Kbits/s Data format: Data bit: 8 bits Parity bit: none Stop bit: 1bit 5.4.9 HANDSET MICROPHONE INPUT (PINS 37, 38) The handset differential inputs MICIP and MICIN can be amplified by the differential handset microphone amplifier. This amplifier has a gain of 25.6 dB. Handset Mic Input Parameter/Conditions Maximum Input Range – Mic(+) to Mic(-) Inputs 3 dBm0 (Max.

Enfora Enabler III LPP 5.5 SUBSCRIBER IDENTITY MODULE (SIM) (PINS 42, 43, 44, 45, 46) The SIM, an integral part of any GSM terminal device, is a “smart card” that is programmed with subscriber information: • The user information consists of an International Mobile Subscriber Identity (IMSI) number, which is registered with the GSM provider, and an encryption Ki (pronounced "key"). This information consists of a MSP430 processor and memory installed on a plastic card.
Enfora Enabler III LPP The transorb must have a low junction capacitance (typically < 10 pf) such as the following part: Example: Manufacturer: On Semi Manufacturer PN: NSQA6V8AW5T2G Figure 7 - Remote SIM Interface Pin Name Pin Number Signal Direction Description SIM_VDD 45 O SIM VDD SIM_CLK 43 O Card Reference Clock SIM_RST 42 O Card Reset SIM_I/O 44 I/O Card I/O Data SIMDTC 46 I Card Detect The module provides the regulated supply voltage for the SIM-card and the circuitry to de
Enfora Enabler III LPP be configured to detect a SIM insertion when the SIMDTC is either pulled to ground or left floating. It can configured to detect either just a SIM removal or both removal and insertion. When the module detects a SIM removal, it will de-register from the network. When the module is configured to and detects a SIM insertion, it will reset the module and re-register on the network.
Enfora Enabler III LPP 5.6 ANTENNA The LPP0208 module has two RF antenna connections. One connection is for the GSM section of the module and the other for GPS. Please be sure to follow proper RF design practices when designing the antennas. 5.6.1 GSM A GSM antenna should be designed from proper RF design practices. 5.6.2 GPS The GPS_ANT is the RF connection from the GPS antenna; no external LNA is required. The LPP0208 can support both passive and active GPS antenna.
