Pinout description:

There are 12 total pins on the small SIM800L two parallel rows of six headers.

GND: Ground   VCC:  Supply Voltage

RST: Reset pin for SIM800L

RXD: Serial communication (Receiver Pin)

TXD: Serial communication  (Transfer Pin)

NET: Antenna

RING: Low state while receiving call

DTR: Sleep mode

MICP: Microphone +   MICN: Microphone –

SPKP: Speaker +        SKPN: Speaker –






Its advisable to use diodes 1N4007 in series , as shown below to drop down supply volt below 4.7v


DC-DC BUCK converters based on LM2596 can also be used for power source.
