Firmware of the Nucleo expansion board for low power measurement

ソフトウェア入手 データブリーフのダウンロード



The STM32-LPM01-XN is STMicroelectronics firmware dedicated to the X-NUCLEO-LPM01A expansion board for the power consumption measurement of target boards.

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).

STM32-LPM01-XN operates the X-NUCLEO-LPM01A 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).

STM32-LPM01-XN enables to supply and measure the consumption of STM32 Nucleo-32, Nucleo-64 or Nucleo-144 boards, using Arduino™ connectors. Alternatively, it can be used to supply and measure the consumption of any target connected by wires via the basic connector of the X-NUCLEO-LPM01A.
