Hardware Reference Guide
The Qualcomm® Robotics RB1 and Qualcomm® Robotics RB2 Development kits expand upon the 96Boards Consumer Edition (CE) Specification. They offer flexible options for development and commercialization. The development boards offer prototyping, off-the-shelf SOM solutions to speed commercialization, and flexibility for chip-on-board designs.
The Qualcomm Robotics RB1 and Qualcomm Robotics RB2 development kits consist of the Qualcomm® QRB2210 and Qualcomm® QRB4210 SOMs respectively. The SOMs are soldered down onto the interposer board and mounted on the robotics main board, which houses many peripheral interfaces and a robust expansion interface that supports the addition of multiple stackable mezzanine cards for added functionality.
