SIM900 ntawm SIMCOM Quad-band GSM GPRS Shield Development Board + Kav hlau txais xov
Cov Lus Qhia Txog
Lub GPRS Shield yog tsim los ntawm SIM900 module ntawm SIMCOM thiab tau tshaj cov Arduino thiab nws cov clones. GPRS Shield qhia koj ib txoj kev sib txuas lus siv GSM xov tooj ntawm tes. Lub shield tso cai rau koj mus cuag SMS, MMS, GPRS thiab Suab ntawm UART los ntawm xa AT commands (GSM 07.07, 07.05 thiab SIMCOM enhanced AT Commands). Lub shield kuj muaj 12 GPIOs, 2 PWM thiab ib qho ADC ntawm SIM900 module (Lawv yog cov 2V8 logic) tam sim no onboard.
Nta:
Quad-Band 850/900/1800/1900 MHz - yuav ua haujlwm hauv GSM networks hauv txhua lub teb chaws thoob qab ntuj.
