- I2C interface (level translated to +3.3V or +5V)
interface (level translated to +3.3V)
- GPIO's (level translated
- Standard prototyping area with 0.1" x 0.1" matrix
embedded ATmega328 processor that can be user programmed. The
ATmega328 can be jumpered to run at 3.3V or 5V
- The ATmega328 is Arduino compatible
- The BeagleBoard
can communicate to the ATmega328 processor via its
second RS232 serial port
- The BeagleBoard can turn the power to the ATmega328 on or off
one of it's GPIO pins
Vollständige Englische Beschreibung:
The Trainer board is compatible with all
revisions of the
(both Rev B and Rev C BeagleBoards).
The Trainer provides an interface to the BeagleBoard's I²C port. The
I²C signals are level translated to either +3.3V or +5V (user selectable
with a jumper). The I²C signals are located next the the prototyping
The Trainer provides an interface the the BeagleBoard's SPI port and the
signals are level translated to +3.3V. The SPI signals are located
next to the prototyping area.
The Trainer provides an interface to several of the BeagleBoard's GPIO
signals. The GPIO
signals are level translated to +3.3V and are located next to the
/ Breakout Area
The Trainer provides a standard prototyping / breakout area with a
standard 0.1" x 0.1" matrix. The user can use this area to prototype
their design and interface it to either the BeagleBoard's level
translated signals or to the ATmega328's I/O pins.
An ATmega328 embedded processor is located on the Trainer board that is
user programmable. The ATmega328 is compatible with the Arduino and
the ATmega328's I/O signals are available next to the prototyping area.
The ATmega328 can be user jumpered to run at +3.3V or +5V. One of the
BeagleBoard's GPIO signals controls the ATmega328's power supply and
can turn on or off the power to the ATmega328. The ATmega328 has an
8.0 Mhz oscillator.
The Trainer provides a second RS-232 serial port that interfaces to the
ATmega328 processor. Commands can be transmitted back and forth between
the BeagleBoard and ATmega328 processor.
Board size = 3.0 inches x 3.1 inches (same size as the BeagleBoard).
Each Trainer board comes with the following:
- Four (4) board standoffs
- Four (4) board to
- Eight (8) screws
- 1 male expansion connector (2x14
male header - unshrouded) that
will need to be soldered into the BeagleBoard's expansion header.
1) The expansion header (J3) on the BeagleBoard does not come populated
with a connector. We supply one connector (2x14 male header) that has
to be soldered into the BeagleBoard's expansion header by the user.
