INTRODUCTION
AVR-H128-CAN is inexpensive way to develop and prototype circuits with
AT90CAN128 without need to deal with SMD soldering. All microcontroller pins
are available on extension header with 0.1" and power supply, oscillators, ICSP,
JTAG are wired, 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 with 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
working with static sensitive devices should be applied when working with this
board.
BOARD USE REQUIREMENTS
Cables:
The cable you will need depends on the programmer/debugger you use. If
you use AVR-JTAG or AVR-PG1 you will need RS232, if you use AVR-USB-JTAG
or AVR-ISP500/TINY/ISO you will need 1.8 m A-B USB cable, if you use AVR-
PG2, you will 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.
Software:
AVR C compiler.
