X-NUCLEO-LPM01A STMicroelectronics

X-NUCLEO-LPM01A STM32 Nucleo expansion board for power consumption measurement Data brief Features STM32L496VGT6 microcontroller featuring Arm Cortex -M4 core at 80 MHz / 100 DMIPS and three 12-bit ADC at 5 Msps Programmable voltage source from 1.8 V to 3.3 V Static current measurement from 1 nA to 200 mA Dynamic measurements: 100 kHz bandwidth, 3.2 Msps sampling rate Current from 100 nA to 50 mA Power measurement from 180 nW to 165 mW Energy measurement computation by power measurement time integration Execution of EEMBC ULPMark tests Mode standalone: Monochrome LCD, 2 lines of 16 characters with backlight Picture is not contractual. 4-direction joystick with selection button Enter and Reset push-buttons advanced power consumption measurement capability. Mode controlled: Connection to a PC through USB FS It performs consumption averaging (static micro-B receptacle measurement up to 200 mA) as well as real-time analysis (dynamic measurement up to 50 mA with Command line (virtual COM port) or 100 kHz bandwidth). STM32CubeMonitor-Power PC tool. The X-NUCLEO-LPM01A operates either in 4 status LEDs standalone mode (using its LCD, joystick and Target board connectors: button to display static measurements), or in Arduino Uno and Nano connectors controlled mode connected to host PC via USB Basic connector (white): 4 wires (using the STM32CubeMonitor-Power software tool with its comprehensive graphical user Flexible input power-supply options: interface). USB micro-B (VBUS) It can be used to supply and measure the External power connector (7 V to 10 V) consumption of STM32 Nucleo-32, Nucleo-64 or Arduino Uno and Nano connectors (pin Nucleo-144 boards, using Arduino connectors. 5V) Alternatively, it supplies and measures the consumption of any target connected by wires via Description the basic connector. The X-NUCLEO-LPM01A is a 1.8 V to 3.3 V programmable power supply source with March 2018 DB3347 Rev 2 1/4 For further information contact your local STMicroelectronics sales office. www.st.comGeneral information X-NUCLEO-LPM01A General information The X-NUCLEO-LPM01A expansion board firmware runs on the STM32L496VGT6 Arm -based device. System requirements Windows OS (7, 8 and 10), Linux 64-bit or macOS USB Type-A to Micro-B cable Embedded software The X-NUCLEO-LPM01A expansion board firmware is preloaded. The latest firmware version (reference code: STM32-LPM01-XN) can be downloaded from the www.st.com/stm32softwaretools web page. The firmware controls the board and provides a plug-and-play solution for current measurement. It can be used in two main modes: Standalone mode: power-supply the board by USB cable or external +5V source, then follow the instructions on LCD screen. Controlled by host mode: refer to Section : PC software tool. For more information on embedded software and FW upgrade procedure, refer to user manual UM2269. PC software tool The X-NUCLEO-LPM01A expansion board can be controlled by a computer through USB. Computer driver for USB virtual COM port (VCP) is required: STM32 Virtual COM Port Driver (reference code: STSW-STM32102) can be downloaded from www.st.com. The board can be controlled: Via a COM port terminal with commands. Type command help for list of commands available. For more information on commands, please refer to user manual UM2269. Via a graphical user interface using the STM32CubeMonitor-Power software tool (reference code: STM32CubeMonPwr) available at www.st.com/stm32softwaretools.
