製品概要

概要

The X-NUCLEO-LPM01A is a 1.8 V to 3.3 V programmable power supply source with advanced power consumption measurement capability.

It performs consumption averaging (static measurement up to 200 mA) as well as real-time analysis (dynamic measurement up to 50 mA with 100 kHz bandwidth).

The X-NUCLEO-LPM01A operates either in standalone mode (using its LCD, joystick and button to display static measurements), or in controlled mode connected to host PC via USB (using the STM32CubeMonitor-Power software tool with its comprehensive graphical user interface).

It can be used to supply and measure the consumption of STM32 Nucleo-32, Nucleo-64 or Nucleo-144 boards, using Arduino connectors. Alternatively, it supplies and measures the consumption of any target connected by wires via the basic connector.
