The EEZ BB3+ represents the successor to the BB3 project, which would bring a series of modifications and improvements starting from the MCU/CPU slot for a replaceable main processor, support for an external high resolution monitor, a larger TFT display with a capacitive touchscreen panel. The upgraded peripheral DIB2 backplane offers faster communication thanks to the introduction of a USB 3.x hub and optional PCIe. The possibility of installing a half-width DIB module allows adding more functions in an even more compact enclosure with better cooling with a larger fan.
