Interfaces
Module interface
Surface mount device with solderable connection pads (SMT application
interface).
Land grid array (LGA) technology ensures high solder joint reliability and
provides the possibility to use an optional module mounting socket.
2 serial interfaces
ASC0:
•
8-wire modem interface with status and control lines, unbalanced, asyn-
chronous
•
Adjustable baud rates: 1,200bps to 230,400bps
•
Autobauding: 1,200bps to 230
,400
bps
•
Supports RTS0/CTS0 hardware handshake and software XON/XOFF
flow control.
•
Multiplex ability according to GSM 07.10 Multiplexer Protocol.
ASC1:
•
4-wire, unbalanced asynchronous interface
•
Adjustable baud rates: 1,200bps to 230,400bps
•
Supports RTS1/CTS1 hardware handshake and software XON/XOFF
flow control
Audio
1 analog interface (with microphone feeding)
UICC interface
Supported SIM/USIM cards: 3V, 1.8V
External SIM card reader has to be connected via interface connector (note
that card reader is not part of BGS2-E/BGS2-W)
GPIO interface
GPIO interface with 10 GPIO lines. The GPIO interface is shared with an
I2C interface, LED signalling and PWM functionality.
Antenna
