IPEC-1 ESP32E ATM90E32 DAC IoT Power Energy Controller Board

Description

IPEC, IoT Power Energy Controller and Monitor, is a 3 phase (or 3 x 1 phase), High-performance Mains Electricity Power Energy Monitor SDK board, designed for Home Automation.

• This product is the version of the board with an Espressif ESP32E (Internal PCB Antenna), an ATM90E32 Energy Monitor and a MCP4728 DAC 
• A Separate IPEX Expansion Board is available, which allows both DAC and ADC Connections.

Antenna

As shown in the above table, IPEC board Antenna options include:

• ESP32E – Internal Wi-Fi/BT antenna (on the ESP32)
• ESP32UE – External Antenna (via U.FL).

The external antenna option will extend the Wi-Fi range if required, or where the IPEC board is housed in a metal enclosure.  On the external antenna boards, use is made of the U.FL connector on the ESP32-WROOM-32UE-N4.  An example of the folded external antenna is shown the photos.

Board Feature Overview

Further details can be found on this expanded comparison chart.

• Current Clamp Inputs
  • IPEC has three main CT Clamp inputs, for Current Measurement Options:
    • 3 x Single phases (such as Mains In, Solar Inverter, Power Circuit etc.)
    • Full Three Phase (3φ. Voltage on each phase is 120 degrees phase shifted, relative to each of the other phases)
    • Split Phase (Dual Phase A and B. Such as USA 2 x 120V)
  • The board has three, or four, standard 3.5mm sockets fitted, so the CT clamp can just plug in.
  • Solder pads are also provided on each current clamp input, where the 3.5mm connection is not available.
  • Burden resistor can be optionally enabled via a solder pad (Not needed for Standard Measurements)
  • Example of CT clamp are the  popular split-core YHDC SCT-013-000 (using a standard 3.5mm mono jack plug).
• Voltage Inputs
  • IPEC has three voltage inputs for safely monitoring mains voltages.  This achieved using a voltage derived from a SELV / Wall AC/AC Power Supply.
  • Voltage Inputs. You can use a single voltage, or multiple voltages input.
  • Three solder pads are provided, with a common ground.
  • Solder Options
• DAC 
  • On-board MCP4728 DAC
  • 12bit – 4 Channels
  • Modulated PWM Output
• Expansion Port
  • I2C and Two channels DAC or PWM Output
  • IPEX Expansion Board Interface
  • JST 6W SH Header
• Board Power
  • IPEM has an on-board SMPS DC Power Supply, which is derived from the AC Power Input,   via an AC terminal block / solder pad, for normal operation.
    • This achieved using a SELV, Wall AC/AC Power Supply.  The supply needs to be 8 to 12 V AC RMS – Ideally 12V.
    • Examples of a suitable Low Voltage 4 to 12V AC power supplies are bell transformers such as the TR7, Byron Din Rail, or DATA01A Transformer.  These may vary in different countries but local sourcing should be straight forward.
• Flashing and Code
  • The IPEM board has a complete Wemos D1 ESP32 Mini compatible interface.
    • Allows ease of interfacing such as from Arduino IDE and Platform IO.
  • The USB input (via Micro USB), can also power the board when developing code.
    • The board can safely have both USB power and AC Power at the same time.
• EEPROM
  • On-board 24C64 EEPROM
    • 64-Kbit (8K x 8 bits)
    • Easy storing of parameters, Logs etc.
    • Accessible using standard I2C EEPROM library
• OLED Display
  • Should you wish to add a display to the IPEM board, a four pin header is provided.
  • Power pins are configurable for pin 1 and 2.

Board Configuration

Solder configuration pads are provided on the bottom of the PCB.
