In addition, to use the additional connections to the SPIRIT1 module and to use the on-

board EEPROM, use the options in Table 6.

Please refer to the schematics for details.

To use the optional connections, modify the firmware based on the STM32 resources used.

3.3

Current measurement

To monitor the power consumption of the entire SPIRIT1 X-NUCLEO-IDS01Ax board,

jumper J1 can be used. Connect an ammeter probe between pins 1 and 2 of the connector

for measurements.
