The control board will provide 5 V power to an attached Raspberry Pi by default. See [[Pololu-Romi-32U4-Carte-Alimentation|section alimentation]] for more details about how power is shared and can be controlled between the two boards.

== ID EEPROM ==
The Romi 32U4 Control Board includes a 32-kilobit (4096-byte) EEPROM that connects to the Raspberry Pi’s ID_SD and ID_SC pins. The EEPROM ships with its contents blank, but you can program it as an ID EEPROM in the format specified by the [https://github.com/raspberrypi/hats spécifications Raspberry Pi HAT] (''RaspberryPi.org, anglais''), using the utilities provided there. When suitably programmed, the EEPROM can help the Raspberry Pi identify and configure itself to work with the Romi 32U4 Control Board.
Write protection for the EEPROM can be enabled by using solder to bridge the surface-mount jumper labeled “WP” next to the EEPROM chip. (The EEPROM is not write-protected by default.)
