INTRODUCTION
AVR-H128-CAN is inexpensive ay to develop and prototype circuits ith
AT90CAN128 ithout need to deal ith SMD soldering. All microcontroller pins
are available on extension header ith 0.1" and po er supply, oscillators, ICSP,
JTAG are ired, so all you need to do is to connect your additional components to
the AVR ports, as the step is 0.1" these headers perfectly fit the prototype sea of pad
boards ith 0.1" step.

ELECTROSTATIC WARNING
The AVR-H128-CAN board is shipped in protective anti-static packaging. The
board must not be subject to high electrostatic potentials. General practice for
orking ith static sensitive devices should be applied hen orking ith this
board.
BOARD USE REQUIREMENTS
Cables: The cable you ill need depends on the programmer/debugger you use. If
you use AVR-JTAG or AVR-PG1 you ill need RS232, if you use AVR-USB-JTAG
or AVR-ISP500/TINY/ISO you ill need 1.8 m A-B USB cable, if you use AVR-
PG2, you ill need LPT cable.
Hardware: One of OLIMEX Programmers/Debuggers – AVR-JTAG, AVR-USB-
JTAG, AVR-ISP500, AVR-ISP500-TINY, AVR-ISP500-ISO, AVR-PG1, AVR-PG2.
