Imodyuli ye-GPRS yeArduino ene-Antenna yePCB
Umzekelo: SIM800L GPRS
Incwadi yokusebenzisa
Inkcazo yezikhonkwane:
Igama lezikhonkwane Inkcazo
I-5v interface yamandla Amandla kwimodyuli
QHAGAMSHELANA NE-DC5v
GND
Ujongano lwe-VDD TTL UART Ujongano lwe-serial ye-TTL UART, ungaqhagamshela i-MCU njenge-51MCU okanye i-ARM, okanye i-MSP430 ngokuthe ngqo. Iphini ye-VDD isetyenziselwa ukuhambelana nomthamotage ye TTL.
SIM_TXD
SIM_RXD
GND ukuba eli phini alisetyenziswa, hlala livuliwe
RST RST umnqongo, ukuba le pin ayisetyenziswanga, gcina ivuliwe
