MODULE HARDWARE
POWERING THE ADE9153A SHIELD
The EV-ADE9153ASHIELDZ is powered from 5 V coming from
Arduino. By default, the 5 V SPI jumper is connected and the board
can be directly connected to Arduino Uno. To use Arduino Zero or
any 3.3 V microcontroller unit (MCU), disconnect the 5 V SPI
jumper and connect a 3 V SPI jumper to ensure that the correct
voltage is applied on the Arduino pins.

ARDUINO UNO AND ARDUINO ZERO
The ADE9153A shield has Arduino R3 headers directly compatible
with Arduino Uno and Arduino Zero. The Arduino pins used
by the ADE9153A shield are described in Table 1.

ESP8266 WIFI SYSTEM ON CHIP (SOC)
The shield can also be used with the ESP8266 WiFi SOC. The
on-board header makes the shield compatible with the ESP8266
ESP-12E Node MCU. To use the ESP8266, perform the following
actions (note that these actions do not need to be performed in
order):
Populate the 15-pin headers, SV1 and SV2.
Disconnect the 5 V SPI jumper and connect a 3 V SPI
jumper to ensure that the correct voltage is applied, as
shown in Figure 2.
Populate 0 Ω resistors on R49, R51, R67, and R68 to establish
the SPI connection. Populate R14 to establish the
RESET
connection
The ESP8266 pins used by the EV-ADE9153ASHIELDZ are
described in Table 2.

CURRENT SENSORS
The EV-ADE9153ASHIELDZ has an on-board, 1 mΩ shunt
resistor. The nominal current through the shunt is 5 A rms and
the maximum allowed current is 10 A rms with a programmable
gain amplifier (PGA) gain value of 16.
VOLTAGE SENSORS
The EV-ADE9153ASHIELDZ has on-board resistor dividers to
attenuate the incoming input voltage. The attenuation factor is
1001. Do not exceed a 240 V rms nominal line to neutral voltage.
