Proto-DB (#28310): Prototyping Daughterboard
General Description
The Proto-DB provides the means to build your own circuits that interface with the MoBoStamp-pe and/or
the MoBoProp motherboards.
Features
Plug-compatible with Parallax motherboards.
•
Ground plane for quiet operation.
•
70 uncommitted plated through-holes on a 0.1" grid for your components.
•
14 grounded through-holes.
•
7 plated through-holes each in two uncommitted voltage busses.
•
11 connecting pads for daughterboard connector supply lines and signals.
•
Application Ideas
Robotic Controls.
•
Custom Sensors.
•
Data Acquisition Circuitry.
•
Industrial Control I/O.
•
Pushbuttons and LEDs.
•
What's Included
What You Need to Provide
Components and wires.
•
Filter and bypass capacitors.
•
Parallax motherboard or DB-Expander.
•
Connector(s) to the outside world.
•
Your imagination!
•
Assembly
The Proto-DB comes in kit form with the circuit board and motherboard connector separate. If you are
using the Proto-DB with a Parallax motherboard, you will need to solder the connector to the board.
