Pumpkin Motherboard Module 2 (MBM 2)
Pumpkin Space Systems
The Motherboard Module (MBM) is part of the CubeSat Kit™ nanosatellite architecture. This is flight hardware (blue). By adding a Pluggable Processor Module (PPM) to the MBM, you create a low-power, 8- or 16-bit MCU/DSC C&DH module for your CubeSat. An MBM + PPM occupies a standard 0.600" (15.24mm) tall module slot, typically at the base of a Pumpkin CubeSat Kit™ structure. The MBM routes the MCU/DSC's I/O pins to the 104-pin CubeSat Kit bus, and provides an RBF switch, an external +5Vdc power input, a USB device port, a battery-backed RTC subsystem, an SPI-interface SD Card, an extra power header, and +5V and GND for use by PC/104 connectors.
