GSM/GPRS/GPS Shield

Description

" SM/GPRS/GPS Shield, Phone Module, Arduino Shield Based on SIM908 Overview GSM/GPRS/GPS Shield is an Arduino shield based on the Quad-band GSM/GPRS/GPS module SIM908. Features General Arduino connectivity, connects to Arduino Board directly NOKIA speaker & mic, supports hands-free phone talk Onboard CP2102 for easily debugging through USB interfere Onboard 74HC125, for time-shared controlling GSM and GPS port through single serial port Earphone insert detection & call vibration Quad-band 850/900/1800/1900MHz GPRS multi-slot class 10 GPRS mobile station class B Compliant to GSM phase 2/2+ Class 4 (2 W @ 850/900 MHz) Class 1 (1 W @ 1800/1900 MHz) Control via AT commands (GSM 07.07, 07.05 and SIMCom enhanced AT Commands) SIM application toolkit Supply voltage range : GPRS: 3.2 ~ 4.8 V GPS: 3.0 ~ 4.5V Operation temperature : -40 °C to +85 °C SMS Point-to-point MO and MT SMS cell broadcast Text and PDU mode Audio Tricodec Half rate (HR) Full rate (FR) Enhanced Full rate (EFR) Hands-free operation Echo cancellation GPRS GPRS class 8/10: max. 85.6 kbps (downlink) PBCCH support Coding schemes CS 1, 2, 3, 4 PPP-stack CSD CSD up to 14.4 kbps USSD Non transparent mode GPS Receiver type 42-channel GPS L1 C/A code High-performance STE engine Sensitivity Tracking: -160 dBm Cold starts : -143 dBm Time-To-First-Fix Cold starts : 30s (typ.) Hot starts : 1s (typ.) Accuracy Horizontal position : <2.5m cep="" li=""> Power consumption (GSM engine in idle mode) Acquisition : 77mA Tracking : 76mA What's on Board Earphone jack : SIM908 2nd analog voice channel output GSM antenna connector : SMA interface Arduino expansion connector : for connecting with an Arduino board GSM antenna connector SIM908 control interface GPS antenna connector USB TO UART interface NOKIA original speaker : SIM908 1st analog voice channel output Arduino reset button SIM908 SIM908 network indicator : blinking slowly when network registration is successful Power indicator Mic : SIM908 1st analog voice channel input SIM card slot CP2102 UART Tx/Rx indicator Power switch 6V~9V DC power jack Vibration motor 74HC125 NCP2890 power amplifier : amplifies the SIM908 1st analog voice channel MIC29302 power chip SIM908 analog output positive jumper : open it when NCP2890 is enabled short it when NCP2890 is disabled SIM908 analog output negative jumper : open it when NCP2890 is enabled short it when NCP2890 is disabled NCP2890 enable jumper : short the EN and VBAT to enable short the EN and GND to disable Photos Dimension Package Contains GSM/GPRS/GPS Shield x 1 GSM Antenna × 1 GPS External Antenna (B) × 1 Speaker chamber × 1 Mounting screws × 2 9V power adapter × 1 USB type A plug to mini-B plug cable x 1 Downloads Development resources: demo codes, schematic, datasheets, etc. Click here to download "
