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:
- via the micro-USB connector
- via the CanSat power supply board
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:
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.
