"The Arduino Portenta breakout board allows easy access to the 80-pin high-density connectors of the Portenta series.
This greatly simplifies prototyping including measurement or control of signals, making the board ideal for developing and designing custom hardware for the Portenta family (for example Portenta H7).
The breakout board offers you among other things:Power buttonSwitch for selecting the boot modeAccess to all signals of the high-density connectorsPower supply via terminalsPower supply backup via CR2032 batteryInterfacesUSB-AGbit EthernetMicroSD slotOpenMV camera portApplicationsPrototypingDevelopment"
