# RB3 Gen 2 Dev Kit hardware overview
RB3 Gen 2 Dev Kit allows you to extend your design by utilizing compatible modules or chipsets.
## Hardware resources
RB3 Gen 2 Dev Kit is available with a system-on-module (SoM) that integrates a system-on-chip (SoC) mounted to an interposer. Connect the SoM and interposer to the main board to support peripheral interfaces and stackable mezzanine or carrier cards.
