MODULE HARDWARE
POWERING THE ADE9000 SHIELD
The EV-ADE9000SHIELDZ requires 3.3 V and 5 V. It is
powered from the 3.3 V power pin and 5 V power pin from
Arduino or ESP8266.
ARDUINO ZERO
The ADE9000 shield has Arduino R3 headers directly
compatible with Arduino Uno and Arduino Zero. Using the
EV-ADE9000SHIELDZ with Arduino Zero or equivalent is
recommended. The Arduino pins used by the ADE9000 shield
are given in Table 1.

GPIO 3 IRQ1 Input (interrupt)
GPIO 6 CF4/DREADY/EVENT Input (interrupt)
GPIO 7 CF3/ZX Input (interrupt)
3.3 V Not applicable Power
5 V Not applicable Power
ESP8266 WIFI MODULE
The shield can also be used with the ESP8266 WiFi module. The
on-board header makes the shield compatible with ESP8266
ESP-12E NodeMCU. To use ESP8266, do the following:
• Solder 15-pin headers (SV1 and SV2)
• Populate 0 Ω resistors on R49, R51, R67, and R68 located
on the bottom of the board to establish an SPI connection.
• Optionally, supply external 5 V at J9 if the computer USB
does not provide enough current during debugging.
The ESP8266 pins used by the EV-ADE9000SHIELDZ are given
in Table 2.

CURRENT SENSORS
The EV-ADE9000SHIELDZ is designed to work directly with
current output current transformers (C Ts). Connect the CT
leads to the SL1, SL2, SL3, and SL4 terminal blocks.
Current Output CTs
The EV-ADE9000SHIELDZ has on-board burden resistors in
differential configuration to allow direct connection with
current output CTs. With a typical 2500:1 CT, the maximum
recommended current is 86 A rms. Refer to the ADE9000
Technical Reference Manual to modify burden resistors for
different current ranges.
Voltage Output CTs
To use voltage output CTs, remove burden Resistors R1, R2, R3,
R4, R10, R11, R19, and R20. The maximum recommended CT
output voltage is ±0.353 V rms.
Rogowski Coils
To use Rogowski coils with EV-ADE9000SHIELDZ, do the
following:
• Remove burden Resistors R1, R2, R3, R4, R10, R11, R19,
and R20.
• Replace 0 Ω Resistors R5, R6, R14, R15, R21, R22, R23, and
R24 with 100 Ω resistors.
• Populate C15, C16, C17, C18, C21, C22, C26, and C28 with
22 nF ceramic C0G grade capacitors.
• In the ADE9000API.h file, do the following:
• Set the INTEN and ININTEN bits in the CONFIG0
register.
• Set DICOEFF to 0xFFFFE000.
• If the Rogowski output signal is too low, increase the
PGA gain.
VOLTAGE SENSORS
The EV-ADE9000SHIELDZ has on-board resistor dividers to
attenuate the incoming input voltage. The attenuation factor is
801. Do not exceed the 240 V rms nominal line to neutral
voltage in the 3-phase, 4-wire (3P4W) wye configuration. In
3-wire delta configuration, when Phase B is used as the reference,
do not exceed 250 V rms line to line voltage. There are 4 mm
banana jacks on board to connect the voltage inputs. Use TPI
A079 or equivalent leads with alligator clips to connect the
voltage inputs.
