Product details
Overview
X-NUCLEO-LPM01A from STMicroelectronics is an ultra-low-power measurement expansion board for STM32 Nucleo development platforms, serving as a precision current-sensing interface between target MCU boards and STM32CubeMonitor-Power software. It supports dynamic current measurement from 100 nA to 50 mA with ~2% accuracy, enables real-time data subsampling at up to 100 kHz sampling rate, and delivers energy computation and ULPBench™ test execution for ULPMark™ scoring in battery-constrained IoT sensor nodes.
For engineers reviewing the X-NUCLEO-LPM01A datasheet, X-NUCLEO-LPM01A pinout, X-NUCLEO-LPM01A application, or X-NUCLEO-LPM01A equivalent, key selection considerations include its native integration with STM32CubeMonitor-Power, nA-range resolution capability, support for trigger-controlled acquisition, and compatibility with STM32L-series ultra-low-power MCUs via Arduino Uno V3 and ST Morpho headers.
Technical Context
The X-NUCLEO-LPM01A functions as a hardware-accelerated analog front-end that digitizes shunt-based current measurements and streams time-stamped samples to host PC software. It implements high-gain, low-noise signal conditioning optimized for sub-microamp detection, with configurable gain stages and internal ADC oversampling to maintain linearity across seven decades of current range.
It interfaces exclusively via I²C to the host Nucleo board's microcontroller, which acts as a bridge to USB virtual COM port-no standalone operation or embedded firmware is present on the LPM01A itself. All control (acquisition frequency, voltage scaling, trigger setup) and post-processing (energy integration, ULPMark™ calculation) occur within STM32CubeMonitor-Power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Range | 100 nA to 50 mA full-scale - enables validation of deep-sleep MCU states and active-mode burst consumption in LP IoT endpoints. |
| Measurement Accuracy | ±2% typical - sufficient for comparative ULPMark™ benchmarking and relative power optimization, not metrology-grade calibration. |
| Sampling Rate | Up to 100 kHz - captures fast transient events such as RF transmission spikes or peripheral wake-up surges without aliasing. |
| Interface | I²C (standard mode) - requires host MCU firmware to forward data to PC; no UART/USB endpoint on board. |
| Physical Interface | Arduino Uno V3 + ST Morpho headers - ensures mechanical and electrical compatibility with all STM32 Nucleo-64 and Nucleo-144 boards. |
| Power Supply | Derived from target Nucleo board (3.3 V or 5 V) - eliminates need for external supply or isolation during measurement sessions. |

FAQ
Is X-NUCLEO-LPM01A a standalone measurement instrument?
No. The X-NUCLEO-LPM01A has no onboard processor, display, or storage. It operates solely as an analog front-end accessory that requires connection to an STM32 Nucleo board and the STM32CubeMonitor-Power PC application to acquire, visualize, and analyze current data.
Does X-NUCLEO-LPM01A support direct USB connection to a PC?
No. It lacks a USB interface. Communication occurs over I²C to the host Nucleo board's MCU, which then relays data to the PC via its built-in ST-LINK/V2-1 USB-to-serial bridge - no additional USB cable or adapter is needed beyond the standard Nucleo USB connection.
Can X-NUCLEO-LPM01A measure voltage directly?
No. It measures current only, using a precision shunt resistor and signal conditioning circuitry. Supply voltage must be monitored separately - STM32CubeMonitor-Power displays voltage only when provided by compatible probes (e.g., STLINK-V3PWR) or configured via external ADC input on the host Nucleo board.
What firmware or drivers are required to use X-NUCLEO-LPM01A?
No user-installed firmware is required on the LPM01A. The host Nucleo board must run the default ST-LINK firmware (shipped preloaded). STM32CubeMonitor-Power includes all necessary USB CDC drivers for Windows, Linux, and macOS - no additional driver installation is needed beyond OS-native CDC support.
