Arduino GPRS Module Me ka PCB Antenna
Model: SIM800L GPRS
Palapala Hoʻohana

ʻIkepili huna

1 ʻO ka wehewehe ʻana o nā pine:

2 Pinout:

3 ʻO Arduino Sample Code:

4 Palapala / Punawai

4.1 Nā kuhikuhi

5 Nā leka pili

ʻO ka wehewehe ʻana o nā pine:

Ka inoa o nā pine wehewehe
5v Power interface E hoʻoikaika i ka module
Hoʻopili iā DC5v
GND
VDD TTL UART interface ʻO ka TTL UART serial interface, hiki iā ʻoe ke hoʻohui i ka MCU e like me 51MCU a i ʻole ARM, a i ʻole MSP430 pololei. Hoʻohana ʻia ka pine o VDD e hoʻohālikelike i ka voltage o ka TTL.
