Contents

The CanSat processor platform provides easy access to data processing and storage. It holds a Gumstix Overo® Computer-on-Module (COM) board.

Power

The COM board can be powered with 5 V:

When using the micro-USB connector power supply:

  • the jumper close to the the COM board should be shorted
  • the jumper on the power supply board should be open on both sides (5 V from batteries or from mini-USB)

Connectors

A breakout board with the following pins on a standard connector has been created:

Gumstix Breakout IOs
Name Direction Level [V] Description
USB5 out 5 Power delivered by the USB connector, not used on the breakout board
AUXL / AUXR in Audio input
HSOLF / HSORF out Analog output
N_RESET in Gumstix reset, connect to GND through button
TXD1 in 3.3 Serial Data In
RXD1 out 3.3 Serial Data Out
GPIO168 in 3.3 General Purpose Input
GPIO67 out 3.3 General Purpose Output
GND Common
VCC33 in 3.3 Power Supply

The USB5 power is connected to the top connector's 5 V pin. On the power board, the 3.3 V is generated for all boards. This is the source of the VCC33 pin which powers the COM board.
