78M6613 User Manuel

78M6613 is the single-phase energy measurement chip designed by MAXIM. It has 22 bits built-in

delta-sigma ADC, 32 bits calculate engine, 8 bits 80515 kernel MPU, and can be widely used in

single-phase ammeter.

According to 78M6613, we manufacture the single-phase energy meter based on Arduino. You can use

PC serial communications software to communicate with this board and received its data by Arduino and

display it on LCD. 78m6613 has high voltage. Pay attention to it during operations. Arduino part,

onbard Uart to USB part are separated from 78M6613, therefore, they will not have high voltage. We

reserved the Wifi shield Io of Arduino. You can use Wifi shield at the same time which can enlarge the

scope of use.

This board uses LCM of 1602. LCD data ports D4-D7 are connected to IO D7-D4 on Arduino. The RS

port is connected to A5 on Arduino and is enable the port A4. Data received by serial can be directly

displayed on LCM through Arduino library. 78M6613 can use CLI mode, receiving serial commands, to

adjust internal information and data output method and etc. Default mode is output voltage, current,

power factor and fact periodically. As the connection way to 78m6613 of Arduino and FT232 is serial as

the same, we suggest unplug the sending pin P5 of FT232 when use Arduino. Similarly, when use USB

serial, unplug serial sending pins P9 and P10 of Arduino.

Note: The output data format of 78m6613 is : voltage value（mV）, current value（mA）, power value

（mW）, power factor, frequency（0.01Hz）.
