ST X-NUCLEO-LPM01A - Power Source from the 5 V Pin of the Arduino uno or Arduino Nano Connectors; X-NUCLEO-LPM01 A Power Consumption; Figure 8. JP3 (Power from Arduino Setting); Figure 9. CN4 and CN13 +5 V Pin Assignment

Supplying power to the X-NUCLEO-LPM01A UM2243
16/41 UM2243 Rev 2
7.4 Power source from the 5 V pin of the Arduino Uno or Arduino
Nano connectors
A jumper should be inserted in the 'ARD' position of JP3 as shown in Figure 9: CN4 and
CN13 +5V pin assignment. The X-NUCLEO-LPM01A is supplied by a 5 V DC source from
either the Arduino Uno connector (CN4) or the Arduino Nano connector (CN13). See
Figure 3: X-NUCLEO-LPM01A layout top view for the CN4 and CN13 placements.

7.5 X-NUCLEO-LPM01A power consumption
• 140 mA max (700 mW with 5 V power source); static or dynamic mode during
acquisition, no target board load.
• 340 mA max (1700 mW with 5 V power source); static measurement mode during
acqu
isition, target board at full load (200 mA)
• 190 mA max (950 mW with 5 V power source); static measurement mode during
acqu
isition, target board at full load (50 mA)
Note: Current consumptions are the same regardless power supply
input source (USB, Ext Pwr,
Arduino 5 V pin).
