The Motherboard Module 2 (MBM2) is part of the CubeSat Kit nanosatellite architecture and is Pumpkin's standard flight computer in the SUPERNOVA spacecraft product line. The MBM2 hosts the open-source BeagleBone Black (BBB) as a single CSK compatible module. The BBB is a 1 GHz ARM processor running Linux. A commercial-grade or better BBB is included with purchase of an MBM2.


The MBM2+BBB fully supports 4.5x UART, an I2C bus, 6x GPIO, USB host, USB device and 10/100Mbps Ethernet communications. Also included are RS-422 + LVTTL SPI/UART/GPIO PHY for transceiver interfaces.


The MBM2 provides the necessary circuitry to safely and automatically enable BBB access to the 104-pin CubeSat Kit bus, a maskable WDT subsystem, a battery-backed real-time clock (RTC) subsystem, a debug terminal connector, an SPI-interface SD Card and +5Vdc power system switching.


The MBM 2 + BBB occupies a standard 0.600" (15.24mm) tall module slot. A custom heatsink is provided and serves to secure the BBB to the MBM2.

Each MBM2 is supplied with a minimal build of Pumpkin's GUTS flight software (FSW) on its included BeagleBone Black (BBB). The software image provided on the BBB is intended primarily for testing and functional verification of the MBM2+BBB's various features. It contains a pre-configured Linux OS with the device tree configured to enable UART, SD card, real-time clock (RTC), GPIO and I2C functionality with the pin assignments of the 104-pin CSK bus connector as outlined in the MBM2 datasheet. The image also comes with the Pumpkin GUTS MCU service to facilitate querying and commanding Pumpkin SupMCU modules (e.g., the GPSRM1 or the BM2) over I2C. This allows some basic development of interfaces/applications that run on the MBM2+BBB. This software is a small subset of Pumpkin's GUTS FSW and is not meant to directly support mission operations.

MBM2+BBB users must provide their own FSW, either by installing a new image (e.g. Debian/KubOS/etc.) onto the included BBB or by using Pumpkin's GUTS FSW (available at extra cost). Pumpkin can provide the necessary device tree configuration and other basic Linux configuration variables for customers to integrate their own flight software.
This module is compatible with all CubeSats that conform to the CubeSat Kit Bus standard with its 104-pin connector. It is compatible with any version of Linux that has a device tree that is compatible with the BeagleBone Black (BBB).
