Arduino GPRS Module Nrog PCB kav hlau txais xov
Qauv: SIM800L GPRS
Cov neeg siv phau ntawv
Kev piav qhia ntawm pins:
Lub npe pins Description
5v Fais fab interface Fais fab lub module
Txuas rau DC5v
GND
VDD TTL UART interface Lub TTL UART serial interface, koj tuaj yeem txuas MCU zoo li 51MCU lossis ARM, lossis MSP430 ncaj qha. Tus pin ntawm VDD yog siv los ua kom haum rau voltage TTL.
SIM_TXD
SIM_RXD
GND yog tias tus pin no tsis siv, qhib qhib
RST RST lub module, yog tias tus pin no tsis siv, qhib
