SIM808 GPS GSM GPRS Module For Arduino connecting wire This module is built around

This module is built around NXP PN532

The D-input that meets the set-up and hold time requirements on theLOW-to-HIGH clock transition is stored in the flip-flop and appears at the Q output

Because it doesn't have to touch the object it's measuring

It fits the Arduino Nano form factor

this number is only expected to go high
