Overview
The Cerebot II board is a useful tool for
embedded control and robotics projects for
both students and hobbyists.
Its versatile design and programmable
microcontroller lets you access numerous
peripheral devices and program the board for
multiple uses. The board has many I/O
connectors and power supply options and
supports a number of programming options
including the free Atmel AVR
®
Studio 4, and
WinAVR.
The Cerebot II has a number of connections
for peripheral devices. It provides eight
connectors for attaching Digilent Pmod™
peripheral modules. Digilent peripheral
modules include H-bridges, analog-to-digital
and digital-to-analog converters, speaker
amplifier, switches, buttons, LEDs, as well as
converters for easy connection to RS232,
screw terminals, BNC jacks, servo motors, and
more.
Features include:
•
an ATmega64L microcontroller
•
eight hobby RC servo connectors
•
eight Pmod connectors for Digilent
peripheral module boards
•
an on-board voltage regulator
•
multiple flexible power supply jumper
options
•
support for the Digilent JTAG-3 Parallel
and JTAG-USB programming cables
•
support for the Atmel AVRISP in-
system programmer
•
support for the Atmel AVR JTAGICE
