About
The Motherboard Module 2 (MBM2) is a CubeSat Kit (CSK)-compatible host for the COTS BeagleBone Black (BBB) Rev C single-board computer and compatible variants. When installed onto an MBM2, the BBB interfaces to the CSK electrical bus via standardized signals. It includes additional features like a Real-Time Clock (RTC) with battery backup and a full-size SD Card operating in SPI mode. This MBM2+BBB combination can serve as the on-board computer (OBC) for a wide range of small satellites and similar equipment. The BBB comes pre-installed with a custom Linux-based image, including Pumpkin’s FSW SupMCU service, drivers for BBB and MBM2 peripherals, Python, and Perl. It supports multiple +5V power sources (auto-selected), BBB Ethernet, USB host & device ports, and various I/O on the CSK Bus Connector and other connectors. The module features power-on fully protected I/O, on-board reset circuitry, independent latchup protection, and a 6-layer gold-plated blue-soldermask PCB with a ground plane for enhanced signal integrity. Hardware revision F was initially released on 20200712.
