The GR-SBC-GR740 single-board computer (SBC) utilizes the GR740, a quad-core LEON4FT radiation-hardened microprocessor. Paired with 512 MiB of EDAC-protected SDRAM, it delivers exceptional performance in a compact form factor, making it the perfect choice to control small satellites and payloads. Furthermore, the board includes mounting holes to simplify its integration across diverse units.
