Siab tshaj li ntawm uno thiab Mega; Chaw nres nkoj dawb txuas, koj tuaj yeem xaiv Hardware Serial port (D0 / D1) los sis Software Serialport (D2 / D3) tswj nws.Qhov GPRS Shield yog teeb thiab tswj tau ntawm nws UART siv cov kev cai AT commands.
SIM900 tag nrho cov pins breakout. Tsis yog lub UART chaw nres nkoj thiab debug chaw nres nkoj yuav teeb, tab sis kuj tag nrho cov pins ntawm SIM900 yuav teeb layout rau 2.54 standard suab; Super capacitor zog mov rau RTC.
EFCom tsis yog siv lub khawm rau lub hwj chim xwb, tab sis kuj tseem siv tau cov hlua ntawm Arduino los mus pib dua thiab pib dua tus qauv siv SIM900.
Quad-Band 850/900/1800/1900 MHz Hoob 4 (2 W 850/900 MHz); Hoob 1 (1 W 1800 / 1900MHz); GPRS cov hoob kawm ntau tshaj 10/8; Chaw nres tsheb GPRS chaw nres tsheb B; Ua raws li GSM theem 2/2 +.
