ST X-NUCLEO-LPM01A User Manual

Power supply connections of a target board UM2243
18/41 UM2243 Rev 2
Note: For measurements, jumper JP1 should be always in the ‘normal’, and not in the ‘test’
position. Otherwise it may impact the current measurements results.
Note: As shown in Figure 2: Hardware block diagram, inserting a jumper in the JP4 ‘decoup’
position adds a 2.2 µF decoupling capacitance on the power output voltage (VOUT). It is
recommended
to keep JP4 jumper inserted most of the time to avoid X-NUCLEO-LPM01A
dynamic measurement oscillation, especially when the target board has a decoupling
capacitance of less than 1 µF on its input power supply path.
