STMicroelectronics STEVAL-IPE014V1

Overview

STEVAL-IPE014V1 from STMicroelectronics is a multiphase energy meter daughterboard built around the STPMS2 smart sensor IC, designed to interface with the STEVAL-IPE010V2 motherboard for complete 3-phase metering systems. It supports configurable wiring modes including 3-phase 4-wire RSTN, 3-phase 3-wire RST_, and 1-phase 2-wire _TN with tamper detection, and features four dedicated LED indicators for power status, no-load condition, tamper alert, and reverse current direction.

For engineers reviewing the STEVAL-IPE014V1 datasheet, STEVAL-IPE014V1 pinout, STEVAL-IPE014V1 application, or STEVAL-IPE014V1 equivalent, this board enables rapid validation of polyphase metrology architectures using ST's STPMS2-based signal conditioning and multiplexing, with embedded capacitive power supply and isolated current channel design.

Technical Context

The STEVAL-IPE014V1 implements per-phase analog front-end signal acquisition and time-division multiplexing, interfacing voltage and current inputs to the STPMS2's differential current (cip/cin) and voltage (vip/vin) channels. It uses the STPMS2's internal bandgap reference (VBG), clock synchronization (CLK/DAT/DATn), and mode selection pins (MS0–MS3) to configure measurement topology and system phase count.

Each daughterboard connects via edge-card interface (JP1–JP4) to the STEVAL-IPE010V2 motherboard, delivering digitized, synchronized sample streams to the STPMC1 energy calculation IC. Isolation is achieved through galvanically separated current sensing paths, and power is derived from an embedded capacitive supply referenced to VCC_b.

FAQ

Is STEVAL-IPE014V1 a standalone energy meter?

No. The STEVAL-IPE014V1 is a daughterboard requiring connection to the STEVAL-IPE010V2 motherboard to function. It provides per-phase analog signal conditioning and multiplexing but lacks energy computation logic, which resides in the STPMC1 on the motherboard.

What wiring configurations does it support out-of-the-box?

The board supports seven pre-configured topologies without hardware modification: 3-phase 4-wire RSTN (with tamper), 3-phase 3-wire RST_, 2-phase 3-wire _STN, 1-phase 2-wire _TN (with tamper), and others as listed in the data brief. Configuration is controlled via MS0–MS3 pins and firmware on the motherboard.

Does it include isolation for both voltage and current inputs?

Yes - the current channel is galvanically isolated using discrete components and layout separation. Voltage inputs are referenced to the board's common ground but are scaled and filtered for safe interface with the STPMS2's vip/vin pins; full system isolation depends on motherboard-level implementation.

Can multiple STEVAL-IPE014V1 boards be used with one STEVAL-IPE010V2?

Yes - the STEVAL-IPE010V2 motherboard is designed to host up to three STEVAL-IPE014V1 daughterboards, enabling full 3-phase metering. Each daughterboard connects via dedicated edge-card slots (J1–J3) and operates independently under shared clock and control signals.
