OVERVIEW

Space computer module for ultra-small satellites

SC-OBC Module A1

The SC-OBC MODULE A1 board is optimized for use in CubeSats. We use technology cultivated by JAXA for reliable, safe use on the International Space Station. These boards use a Xilinx Artix-7 FPGA, allowing flexible configuration and multiple interface options. Not limited to CubeSats, our boards can also benefit other spacecraft and even terrestrial applications here on Earth.

USE CASES

During installation in our own satellite,

the SC-OBC Module A1 board was mounted to an interface board with a PC104 form factor.

A satellite equipped with the SC-OBC Module A1 installed on an interface board.
